Upgrade jailbroken iPhone to iOS 6 and preserve baseband with redsn0w

Update February 20th

With iOS6.1.2 now available the window to upgrade jailbroken devices to iOS 6.1 is now closed, iOS 6.1.2 is currently not jailbreakable with redsn0w (but it is with evasion!)- this post will be updated when the next version of redsn0w is released to jailbreak iOS 6.1.2

In the meantime this information below will only work if you have your SHSH blobs saved locally or on Cydia.

If you don’t rely on an iPhone unlock with ultrasn0w then you can update and  jailbreak ios 6.0 – 6.1.2  with evasion – guide here

The latest version of redsn0w allows iPhone 3GS and iPhone4 to be jailbroken to iOS6.

The jailbreak is a mixture of tethered and unthered boots at this stage:

  • iPhone 3GS Old Boot Rom – untethered
  • iPhone 3GS New Boot Rom – tethered
  • iPhone 4 – tethered
  • iPod Touch 4th Gen – tethered
  • iPhone 4S
  • iPhone 5
  • iPod Touch 5th Gen
  • iPad 2 & 3
  • iPad 1 – max iOS 5.1.1 

If you don’t care about the baseband and are already working with an unlocked IMEI, follow this quicker jailbreak guide.

If you are looking to downgrade to an earlier iOS version such as from iOS 6 to iOS 5.x or  downgrade between iOS 5.1.1 or 5.1 or 5.0.1 and your SHSH blobs are on Cydia you can use the same restore procedure in the guide to restore to that iOS the only difference is that you need to specify the correct iOS IPSW that you want to downgrade to.

You can download those IPSWs from here. And if you need that baseband preserved just remember to click on the preserve baseband when prompted.

How to upgrade a previously jailbroken iPhone to iOS 6 and preserve the baseband.

The process of getting this job done requires a number of steps (but are easily done), which are downloading the official iOS 6 firmware from Apple, upgrading iTunes to the latest version, getting the latest redsn0w software from the dev team. If you are new to this it can well be intimidating with loads of jargon but take your time and go through the information below. This process has been tested and successfully installed/Jailbroken on a iPhone 3GS old boot rom device that has been previously jailbroken.

Please note at this point ‘ultrasn0w‘ is not ready for iOS6 eventhough Cydia is, so if you rely on your baseband being unlocked by ultrasnow you need to wait 2 days before it is released.. But if you still want your baseband preserved but don’t rely on ultrasn0w then you are good to go. You also can bypass ultrasn0w and just pay out the original carrier to unlock the phone by using an online service  like cutyoursim.com

Previously users had to create their own custom IPSW files, but the latest redsnow avoids this. This will not work on iPhone 4s and iPad2/iPad2 known as A5 devices.

Get the iphone into DFU Mode

8 ) with the device connected and turned off – when you click next  you go through the DFU mode process

DFU Mode Steps

- the dfu mode process requires fingers on certain buttons  for certain amount of time – don’t worry if you stuff it up, you’ll be told you did and you can try again.

dfu mode failed

- Stop go back and try again if you fail miserably

9)  - Otherwise redsn0w will prepare a restore image and restore to your device maintaining your baseband and verify the restore

Now your iPhone has iOS6 with a preserved baseband – now to Activate and restore from iTunes, go through the screens on the iPhone reboot and activate the device from the questions asked.

Restore from iTunes

11 ) Launch iTunes – click your device and restore from backup

ios6-jailbreak-restore-itunes

ios6-jailbreak-restore-itunes

After the restore, the iPhone reboots and asks for Location Services and iCloud services account details, in the background let iTunes sync the device and copy apps, music, books, movies – this can take a long time….

To Jailbreak

1) To jailbreak and install Cydia: -  launch redsn0w again

ios6-jailbreak-install-cydia

ios6-jailbreak-install-cydia

2) Click on install Cydia

ios6-jailbreak-install-cydia-check

ios6-jailbreak-install-cydia-check

3) You then have to enter the PwnedDFU mode again, so follow the onscreen instructions -

ios6-jailbreak-dfu-mode

ios6-jailbreak-dfu-mode

When you fail to get into DFU you are told about it and you are left with a black screen – press and hold power and home buttons for up to 30 secs until you see the Apple logo.

4) After rebooting, launch Cydia on the iPhone, the app will ask you what type of user you are – just go with ‘user‘ unless you want more and tap ‘done’.

That is the process finished, iOS is updated using custom IPSW files, device is jailbroken and unlocked, information below is additional and will help some users.

Additional iPhone Jailbreaking Info

Note on Tethered Boot !

If your iPhone requires a tethered boot this means that the device requires a software jumpstart (everytime it is booted) to operate after being jailbroken, there are a few apps that can do this but redsn0w also has the function built in. So if you have successfully jailbroke but are stuck on iPhone Apple logo, spinning gear on iPhone boot up, connect the iPhone, launch redsn0w > Extras. Then ‘just boot tethered right now’. This also applies if Cydia crashes on launch or you get a white icon – this means that a tethered boot is also required but is known as a semi-tethered boot as the iPhone can reboot without assistance but to be in a jailbroken state needs a tethered boot. The only iPhone that can boot untethered on this redsn0w/jailbreak is the old bootrom iPhone 3GS.

iphone-tethered-boot-apple-logo

iphone-tethered-boot-apple-logo

What boot-rom am I?

Check your iPhone 3GS serial number, on iPhone – Settings > General > About Look for the Serial Number – if the 4th & 5th digits are below 40 you are lucky and have the old boot-rom. To be absolutely sure about the boot rom – check if you have iboot 359.3

What basebands are unlockable with Ultrasn0w?

iPhone 4

  • 01.59.00

iPhone 3G/3GS

  • 04.26.08
  • 05.11.07
  • 05.12.01
  • 05.13.04
  • 06.15.00

The official basebands installed for iOS6 these are not unlockable

  • iPhone 5 1.00.16
  • iPhone 4S 3.0.04
  • iPhone 4 04.12.02
  • iPhone 4 (CDMA) 3.0.04
  • iPhone 3GS 05.16.07
  • iPad3 2.0.02
  • iPad 2 (GSM) 04.12.02
  • iPad 2 (CDMA) 3.0.04

These are not currently unlockable with Ultrasn0w. If you mistakenly upgraded an unlocked/jailbroken iPhone via iTunes to a regular iOS update you will end up on one of these basebands and lose that unlockable functionality.

Epic Fails

Obviously things in life do not always go to the plan, there are some variables that will hinder the process….

This device isn’t eligible for the requested build

Error 160X – The hosts file is blocking Apple’s server gs.apple.com 

Error 160X

- If the hosts file is not blocking then the device did not enter Pwned DFU mode correctly try again with redsn0w – ‘Extras > Pwned DFU’

Stuck in Recovery Mode

 - Use redsn0w or Tiny Umbrella to escape or 20 seconds of ‘home’ and ‘power button’ dual push and hold

No Service

- If the baseband is in unlockable list above then it should work – ultrasn0w or mobile substrate may need a kick in the pants with a re-install

Memory Exhausted

- This is a random error try restarting the computer and have no running applications apart from redsnow – if it still errors try another computer

Unexpected Error 2601

- This is a redsn0w error which was occurring on Windows it is fixed in the latest version of redsn0w

  • leo

    thank you so much for your effort, but mine doesn’t work, maybe because i try to update it myself before seeing this article, so now i still stuck at activation every time, do you have some good suggestion?

    • http://coolestguyplanettech.com Neil Gee

      What is activation? Do you mean the iTunes logo and the USB icon

  • Ran

    So, it’s very possible to upgrade my existing iOS 4.2.1 to iOS 5 even if my phone’s jailbroken? Thanks.

    There is no Custom IPSW button in the Windows version of redsn0w linked

        So when is it expected to come out?

    plz get the windows one!

  • shahbaz khan

    which custom IOS 5 you have uploaded for 3gs, is it base band 6.15.00?

    • http://coolestguyplanettech.com Neil Gee

      Its non-baseband IPSW, it preserves existing baseband on iphone

  • Anonymous

    i have 3gs with base band 05.11.07 and windows user. can i go through with your above procedure with out change of base band.

    • http://coolestguyplanettech.com Neil Gee

      Baseband will be preserved as it is a NO_BB IPSW

  • Anonymous

    you have already uploaded NO_BB file for 3gs. if i select this file so it is assure that the base band will not be changed.

    • http://coolestguyplanettech.com Neil Gee

      I have used previously and my baseband stayed at the same version

  • Idan

    hello I have Mac / 3gs latest version of Itunes and i get from Itunes error 1604 what can I do?

      Maybe a USB error – try another cable and USB port

    for windows/3gs ?

  • Ulissess

    Ia there a way to update my baseband? I downloaded your file since I’m a windows user and bfore that I updated to Ios 5. Anyway to update my baseband to 6.15.00?

    • http://coolestguyplanettech.com Neil Gee

      if you already updated to ios5 what is your baseband now?

      • Ulissess

        Well before I updated the base band was 5.12.00 so I don’t know what it is now since its locked

        • http://coolestguyplanettech.com Neil Gee

          Check on the phone – General > Settings > About > Modem Firmware = XXXXXX

          • Ulissess

            I can’t check though since it locked and I haven’t jailbroken it yet with the file you uploaded for window users. Do you think you can make a custom ipsw with the bandware 6.15.00 already installed?

          • http://coolestguyplanettech.com Neil Gee

            My file is baseband preserving so whatever baseband is on the iphone will be preserved, if you upgraded through regular iOS5 IPSW, your baseband will be the highest level which you cannot downgrade

          • Ulissess

            I just verified on a website that when you update to Ios 5, the baseband goes up to 5.16.30. Do you think you can make a custom ipsw with the baseband 6.15.00 using redsnow for mac? I have a windows pc so i can’t… Id really appreciate it

          • http://coolestguyplanettech.com Neil Gee

            Sorry redsn0w doesn’t allow me to do that – maybe some hints here for u – http://www.iphone4jailbreak.org/baseband-update-06-15-00.html

  • rm23

    what itunes version should we use? the new one 10.5? or something else?

    • http://coolestguyplanettech.com Neil Gee

      Update to the latest version of iTunes

  • http://coolestguyplanettech.com Neil Gee

    Use the Fix Recovery option in redsn0w – also an updated version is released for Windows, link in the post, when you use it make sure it’s extracted to the drive, don’t run from the zip archive

  • Jeff W

    I am a bit foggy on one detail. The custom NO_BB ipsw for windows. Does it matter what your baseband is before you start? I have bb 4.10.01. Should it matter? I want to use my gevey still.
    What i mean is….Is it a general no_bb upgrade or do I have to have the same bb as the person who made it/

    • http://coolestguyplanettech.com Neil Gee

      The baseband isn’t touched in the custom IPSW, your existing one is preserved, redsn0w makes the custom IPSW from the official IPSW and leaves the baseband upgrade component alone.
      When the custom IPSW is made, the software (redsn0w) doesn’t know what baseband you are on.

      • Jeff W

        thank you Neil

        • http://coolestguyplanettech.com Neil Gee

          No worries – let me know how you go!

          • Spomwonderful

            I download the iphone 4gsm ipsw ios5 but when I open it up on redsnow it says unable to parse ipsw, are you sure it really a ipsw

          • http://coolestguyplanettech.com Neil Gee

            It is already custom IPSW – ready for an iTunes restore, redsn0w parses the original IPSW for custom IPSW

          • Spomwonderful

            step 3 custom ipsw. So I should skip that part cuz it wont parse the ipsw I download up top Iphone3,1_5.0_9A334 restore.ipsw.part

          • http://coolestguyplanettech.com Neil Gee

            yes – you have custom ipsw by downloading it – go straight to iTunes restore

          • Spomwonderful

            unknown error (21) when i restore it from Itunes and my bb is 4.10.01 jailbroken now I have no chose but to restore it and update to the ios5 and I will loose my jailbreak. I didnt do it yet but I cant use my phone
             

          • http://coolestguyplanettech.com Neil Gee

            error may be related to security software – disable it and try

  • uzi

    if you have a tethered jailbroken phone and it tells you to reboot your phone after using ultrasn0w, wouldnt the jailbreak go away after the reboot?

    • http://coolestguyplanettech.com Neil Gee

      I don’t think it would as the phone has already been jailbroken – you could only remove the jailbreak by restoring to custom IPSW then it would be unbroken – which you then could jailbreak again.

  • Sharmasourav35

    thank uuuuuuuuuuuuuu

  • http://coolestguyplanettech.com Neil Gee

    if it is not already jailbroken and you upgrade to official IPSW ios5 you will get ios5 baseband,
    if it iis jailbroken you should not use official IPSW anyway.

    • Sebasti_28

      hi neil i have iphone 3gs 4.0.2 already jailbroken. My firmware is 05.13.04. Can i upgrade my iosver 4.0.2 to ios 5? and if suddenly i cannot ugrade to ios 5, can i set again my phone back to 4.0.2?
      thnks in advance…

      • http://coolestguyplanettech.com Neil Gee

        yes you can as long as you have your iOS Custom 4.X.X that you can go back to – make sure you use the NO_BB IPSW when upgrading to iOS5

        • Sebasti_28

          1 more thing neil, if in case i will set back again my version, can i use the newer version 4.3?

          • http://coolestguyplanettech.com Neil Gee

            yes as long as it is a custom IPSW, in the latest redsn0w if you are a Mac user you can also create a iOS 4.3.3 custom IPSW with no baseband upgrade, for Windows use sn0wbreeze

          • Sebasti_28

            hi neil, since you already uploaded the NO_BB….file, can i proceed to Step 5:Connect iPhone – Enter Pwned DFU Mode.Can i skip steps 1 to 4??
            Because i read steps 1-4, it ends up with the NO_BB..file.

          • http://coolestguyplanettech.com Neil Gee

            yes correct

  • Pavle

    my iphone 4 locks on the apple logo after the above mentioned procedure and I had to factory restore it

    • http://coolestguyplanettech.com Neil Gee

      the iphone 4 when jailbroken is a tethered boot, only old boot rom 3GS is tethered, if stuck at apple logo at iphone start up, use redsn0w to boot tethered through the “extras” > “just boot” option.

    • Lirdi

      lol that;s completely normal with a tethered jailbreak buddy just select the boot tethered option, you can see it in the guide right after clicking extras, no need to restore to factory settings or anything, if cydia’s logo is white after this just click it and boot tethered again (reboot, plug, launch resn0w and choose “boot tethered” option), no worries mate!

      • Pavle

        Will try the suggestions from Lirdi and Neil and let you know how I get on. thanks

      • Pavle

        just boot option “worked”, but I wont know until I put in another SIM card (i.e. not my carriers SIM) which will be tomorrow. Many thanks again.

        • http://coolestguyplanettech.com Neil Gee

          Remember that if it is carrier locked, you will need to unlock the iphone, so at the moment it is just jailbroken, you still need to jailbreak it by installing Cydia and then install ultrasn0w as in the guide

  • http://coolestguyplanettech.com Neil Gee

    Try a tethered boot with redsn0w

    • http://twitter.com/liortalmor Lior Talmor

      or get tiny umbrella recovery fix and kick it to its former state, less recommended but doable if no other choice left. try pressing both sleep and home button foor 5-10 secs to get back to apple logo and then boot tethered option of redsn0w? … could be that. dunno…

  • Jeff W

    Then how would you activate the phone if you didn’t have a carrier sim?

    • Jeff W

      nevermind

  • Who90210

    This tutorials works,

    for those of you who had problem on frozen apple.. or not being able to reboot correctly.
    Use the boot feature inside redsn0w (under extra)
    Apparently for each hard boot, it would not work. So we have to boot this using redsn0w everytime. I hope there would be permanent jailbreak solution soon. :)

      – Try changing USB ports

      or

      – Connect the device to iTunes, confirm that the device is in dfu mode
      – shift/Restore and wait for error 1604.
      – When prompted, click OK.
      – Close and reopen iTunes while iPhone remains connected.
      – iPhone should now be recognized in Recovery Mode again.
      – Try to shift/restore again

      It may be carrier locked in which case you need to jailbreak/unlock – have you done that part?

    you cannot downgrade baseband, however you maybe able to upgrade baseband to 6.15 if you are below, redn0w has this option which you would do after you follow the guide, what version baseband did iOS5 put you on?

      I did the same thing , i put bb 04.11.08 can i upgrade to 6.15?

          Hi there, so how do I get my iPhone 4 with iOS 5 (custom ispw) on 04.18.11BB working? Thanks, Pavle

  • Siva Kannedara

    I am facing big problem with ‘No Service’. I am using AT&T carrier. Iphone 3gs. Followed above steps to install IOS 5 and jailbreaked it. Everything working fine. But, ‘No Service’ problem making me crazy.

    • http://coolestguyplanettech.com Neil Gee

      Try to restore again to custom IPSW only – but before you jailbreak activate phone with sim card

      • Pavle

        Looking at this comment, could the cause of my problem be that I activated my phone (during the installation of custom ispw stage) with the original carrier’s SIM (i.e. the SIM to which my phone was locked). Having said that, ultrasn0w should have unlocked it anyways….right?????

        • http://coolestguyplanettech.com Neil Gee

          what is the current baseband?

          • Pavle

            04.11.08

          • http://coolestguyplanettech.com Neil Gee

            this baseband 04.11.08 is iOS5 stock standard, ultrasn0w does not currently support this baseband so it can’t be unlocked (at the moment)

          • Pavle

            But I thought the “point” of the custom ispw was to make it “unlocksble”?? What are my options, can I upgrade my BB as your instructions in the below post? If Yes, then do I have to download the official ispw (can you also point me to a server please) ? Many thanks!!

          • Pavle

            Also, will ultrasn0w ever support this BB? Looking at the posts on the iPhone dev team site, it looks like no one is going to bother…..

  • cmm

    After updating my 3GS on 6.15 baseband to IOS 5, I jail break and installed Cydia but on the restart it freezes. Any fix for this and anyone else encountering this problem?

    • http://coolestguyplanettech.com Neil Gee

      3GS may be new boot rom – have you tried a tethered boot?

  • PS

    Problem::: Redsnow crashes after clicking on the step with Install Cydia  :(

    I used Windows and the custom IPSW from above for a 3GS 05.11.07 new boot rom
    after restore, have not activated the phone but straight going in for the jailbreak

  • Jack

    Hello. Please guide me. I have an iphone 3GS (new boot-rom). I have a firmware version of 05.11.07 and i wish to update my device from 3.1.2 o ios 5. I have an unlocked n jailbroken one and with a tethered boot. If i follow the instructions above, will my phone be jailbroken n unlocked with ios 5?

    • http://coolestguyplanettech.com Neil Gee

      yes you should be OK, as always there is a risk, nothing is guaranteed.

  • mac_n00b

    After i download unltrasn0w to unlock it, do i need the original carrier’s sim cars ? My phone is with virgin mobile but it was with bell originaly. Do i need bell’s or virgin’s sim card ?

    thanks

    • http://coolestguyplanettech.com Neil Gee

      seems like the iphone is not locked as you have had different carriers, so it it’s working with Virgin, that sim should be fine

  • Daniel Thomas

    Hi.  I followed the instructions…. but I am getting an iTunes 3194 error.  Basically after I put into DFU mode, I then connect to iTunes, press restore and hold down the shift key.  Select the No BB rom, iTunes does its stuff them comes back with the 3194 error.  Kinda stuck… I’m running the 6.15.00 baseband on iphone 3Gs 4.1…

  • http://www.facebook.com/chawla.anshul Anshul Chawla

    hey, i have an iphone 3gs with 06.15.00 baseband, i accidentally updated my phone to ios 5 using itunes. now would this custom restore work ? i read in the dev-team blog that i should reflash the 06.15 baseband … but that is not happening ! please help !

    • http://coolestguyplanettech.com Neil Gee

      if the baseband is 6.15 it should be ok

  • Vale0079

    I have a 3gs running on 4.1 with 5.11 baseband. After following your directions and using your IPSW, IT DID UPGRADE THE BASEBAND TO 5.16 which I was unable to UNLOCK with redsnow.
    Why did it do that if you claim the IPSW will not touch the BB?

    • http://coolestguyplanettech.com Neil Gee

      The custom IPSW starting with a prefix of ‘NO_BB’ does not upgrade the baseband the stock IPSW does.

      Which IPSW did you use?

      • Vale0079

        Used the one on your link up top that says Iphone 3gs (http://appldnld.apple.com/iPhone4/041-8356.20111012.SQRDT/iPhone2,1_5.0_9A334_Restore.ipsw) per your instructions.
        Now I’m stuck with 5.16 not being able to unlock.
        Is there a way to downgrade from 5.16? I have SHSH saved…

        • http://coolestguyplanettech.com Neil Gee

          The article in general and Point No.8 clearly states to use the custom NO_BB IPSW when restoring – you have restored to stock IPSW – the stock IPSW is linked to allow users to download and make their own custom IPSW – the instructions are clear.

          The only way that I know to get to an unlockable baseband is to apply the iPad baseband of 6.15.00, I use this and have no drama but it is reported that some lose their GPS function – so if GPS isn’t an issue then go for your life – if it is, then it is a risk that it may be lost.

          • Vale0079

            Crap! I didn’t see that. I guess I’m stuck upgrading to 6.15 and losing GPS if I want to use my phone :(
            Do you have instructions on how to upgrade to 6.15?

  • Rbenitezz

    Hi Neil, I have a 3gs 6.15.00, already jailbreked and unloked, with t-mobile, I download the NO_BB file and installed trough iTunes 10.5 with windows 7. Then I followed the steps and started as a new phone. Without the simcard.It have the cydia and I installed ultrasn0w too and then instal the sim, but can´t recognize the simcard and don´t have signal. Did I miss something? It says no service!!!

    • http://coolestguyplanettech.com Neil Gee

      Hi,

      Try to custom restore again with the sim – activate before jailbreak+unlock – see if that fixes

      • Rbenitezz

        I just did it, First reboot, then custom restore, and it don´t let activate, And I Jailbreked and unlockde again and doesn´t work. No service, any other sugestion, in case not, how can I get back to 4.3.3?

        • http://coolestguyplanettech.com Neil Gee

          since you are already on 6.15 – maybe try and ‘reflash’ the 6.15 baseband from redsn0w

          In redsn0w > Extras > Select IPSW (stock not custom) go back > Jailbreak > Install iPad baseband

  • Ar3joy

    Hi Neil, I just download the redsn0w as a link above, when i start click the CUSTOM IPSW the pop up came out said THIS FEATURE IS NOT YET AVAILABLE ON WINDOW REDSNOW. But im sure that i download a window link not a mac link.. please help me..

    • http://coolestguyplanettech.com Neil Gee

      you need to re-read the post – Windows users cannot make Custom IPSW – you have to download it

  • http://coolestguyplanettech.com Neil Gee

    I don’t think so – maybe a future version of redsn0w

  • Lkaplan00

    Your instructions were great. I know nothing about setting up an Iphone and wanted to jailbreak and unlock from scratch. The custom IPSW you uploaded was the KEY to my problem as I bought my Iphone already on ios5 used and couldn’t download ios5 thru itunes (they wanted me to have a SIM but for it to recognize my SIM I needed this phone unlocked – how circular!). Redsnow took care of the rest, and I’m glad you decided to include the part of “tethered reboot” because I freaked out when I saw that locked Apple screen. Thanks so much!

    • http://coolestguyplanettech.com Neil Gee

      glad it worked out!

  • Mike

    Great instructions! But, my 3Gs old boot rom is not untethered.  I need to use redsnow to jumpstart.

    • http://coolestguyplanettech.com Neil Gee

      thats odd whats the 4th and 5th numbers on the serial number?

      • np

        NP

        M’n 4th and 5th numbers are 1 respectively 2 (12) but also not untethered.
        I switched back to 4.3.3

        • Mikeyr379

          I can deal with tethered jailbreak and I’m not having battery issues so it’s ok for now.

      • Mike

        4th and 5th numbers are 22

  • Seba

    Thanks!
    Do you have any ideas when will be available to unlock baseband 04.10.01?

    • http://coolestguyplanettech.com Neil Gee

      no sorry – thats all down to the developers of redsn0w -

  • Happyim

    is this ios 5 ipsw will not update my iphone 4 baseband ????????

    • http://coolestguyplanettech.com Neil Gee

      the NO_BB IPSW is made from the latest redsn0w and preserves existing baseband

  • Raji Daou

    hi, if i have BB 03.10.01 and i upgrade to OS 5 with your custom IPSW. Can i use gevey sim to unlock my iphone 4g.

    • http://coolestguyplanettech.com Neil Gee

      sorry don’t know about gevey sim

  • Dimentianon_hazardous

    I have an iPhone 4 with iOS 5, already jailbroken. Now it’s off because of lack of battery, so in order to turn it on i need to use the “just boot” part in the redsn0w, right? the problem is that when i do that, it ends with “no identifying data fetched” and i can’t go on. What’s the problem? do i need to have the ipsw 5 on the computer i am trying this? (it’s a windows vista) (my iphone was updgraded to iOS 5 on another computer)

    • http://coolestguyplanettech.com Neil Gee

      yes redsn0w needs to have the ipsw selected on the computer

      • Dimentianon_hazardous

        Ok, now i have another problem. My redsn0w version is “redsn0w_wi_0.9.9b7″ and i have just downloaded the ipsw from the link it was posted here for windows, so i have the ipsw: “NO_BB_iPhone3_1_5.0_9A223_Restore”. The problem now is that when i go to “select ipsw” and i pick the one i have downloaded it ways: “That ipsw is not supported by this version of redsn0w”
        What can i do now? please i need some help, thanks

        • http://coolestguyplanettech.com Neil Gee

          You use the custom IPSW directly with the iTune restore part of the guide, not with redsn0w

          • Dimentianon_hazardous

            Yes, that worked. I downloaded the non modifyed ipsw. When “booting now” i noticed it got stuck on the part “limera1n” but, after trying turning the firewall off, and running redsn0w as administrator it totally worked! now i have finally on my iphone, thanks a lot!

  • Krgonza

    I have a problem. After putting the phone on DFU mode, I go to iTunes and it’s telling me that the phone is on recovery mode and I need to restore it. Please help!

    • http://coolestguyplanettech.com Neil Gee

      thats what you want right? – so if you are restoring from the custom NO_BB then shift/option click restore in iTunes – go to the NO_BB firmware and restore

  • Egal

    How can i Upgrade from iOS 4.3.3 BB 02.10.04 to iOS 5 BB 04.10.01 ? (With iOS 5 BB 02.10.04 i don’t receive a signal)

  • Semi_heart

    i have iphone 4 4.3.5  tethered and i want to upgrade it  to ios5 and jailbreak it..but  will i loose my files and should do install all cydia  things again ?

    • http://coolestguyplanettech.com Neil Gee

      – your files should be in an iTunes backup – check under the devices tab in Preferences
      – yes you would need to install cydia again
      – remember that your iphone would be tethered in iOS5

    No Service problem.
    I have an iphone 3gs with 06.15.00 baseband, i accidentally updated my phone to ios 5 using iTunes.After that I followed instructions above : 
    1. Used UN_BB .ipsw file in iTunes,
    2. jailbraik with latest redsn0w.
    3. After rebooting, launch Cydia on the iPhone, and install ultrasn0w.

    Reboot (tethered), BUT,  “No Service”.

    Neil, please help me.

     

    • http://coolestguyplanettech.com Neil Gee

      try to toggle airplane mode on/off – also reinsert SIM – see what happens

    • http://coolestguyplanettech.com Neil Gee

      if that doesn’t work you will need to re-flash the 6.15 baseband with redn0w

      • http://www.facebook.com/rubenalbania Ruben Al

        I re-flashed 6.15 baseband 
        (In redsn0w > Extras > Select IPSW (stock not custom) go back > Jailbreak > Install iPad baseband)
        After that I closed redsn0w. 
        I run redsn0w again, Extra – Just Boot Tethered, DFU mode… but iPhone did not turn on.

        Any suggestion?

        To start steps from the begining? 

        from iTunes restore custom ipsw file, jailbreak with redsnow, and install ultrasnow?

        thanks.

        • http://coolestguyplanettech.com Neil Gee

          after you flashed – and before just boot tethered – point redsn0w to stock IPSW and try just boot tethered

          • http://www.facebook.com/rubenalbania Ruben Al

            Yeaaaahhhhh!

            It works man!
            u r genius :)

             

  • Johan

    Hello, 
    I have iphone 4 on ios 4.0, unlocked with baseband 01.59.00 
    I want to jailbreak and unlock (preserve my baseband) it using windows.

    Correct me regarding the procedure:
    1. Download Redsnow_win_0.0.9b7.zip and given link above for custom IPSW –>custom IPSW iOS5 for iPhone 4 GSM
    2. Open redsnow and go to DFU mode
    3. Open itunes, shift click restore and use No_BB file
    4. Jailbreak using redsnow
    5. Go to Cydia and install ultrasnow
    6. Go to Cydia and install semitethered

    My questions:
    1. Does your link above regarding custom IPSW iOs 4 work in windows? 
    2. Does push notification affected if I jailbreak the device, such as imessage? (I have the original simcard but using different carriers, should I use the original one while jailbreaking it and switch to my current simcard after I use ultrasnow, or the other way around? 

    I appreciate your help, thanks! 

     

    • http://coolestguyplanettech.com Neil Gee

      - custom IPSW iOS works cross platform both Windows/Mac
      - probably best use orginal sim while jailbreak – swap to other sim after ultrasn0w is installed

      • johan

        Thanks a lot Neil, it works. 

        It preserve my baseband and I unlocked it! 
        But got some problem with apn setting and went to use http://help.benm.at/. 
        I also did receive error itunes 3194, but it related with tinyumbrella. but solved!

        Thanks a lot!!!

  • Johan

    I forgot to ask, what is the difference between custom IPSW built using redsnow 0.0.9b5 and redsnow 0.0.9b7? 

    Thus, after I download and restore my iphone to Custom IPSW, should i use redsnow 0.0.9b5 or redsnow 0.0.9b7  to jailbreak the device? 

    • http://coolestguyplanettech.com Neil Gee

      custom IPSW iOS 5 built with redsn0w 9.9.b6 had a glitch with location services for 3GS – build with 9.9b7 fixed that glitch

      • Johan

        Then,is it better to use the custom IPSW from your link above or should I wait until the new custom IPSW built using 9.9b7? 

        Is it okay to use custom IPSW from 9.9b5 and jailbreak it using 9.9b7?

        Thanks! 

        • http://coolestguyplanettech.com Neil Gee

          the b5 version is ok for iphone 4 – my custom IPSW are b5 for iphone 4 and b6 for 3GS – you are iphone 4 so yours is ok on b5 version

  • Ken

    Hello,

    After following all the instruction, my iphone 3gs works fine, have sevice and all my previous settings. The only I have encountered is that it will not reboot. I have to use RedsnOw to reboot tethered to get to restart. any suggestions?

    • http://coolestguyplanettech.com Neil Gee

      it must be a new boot room 3GS – which does require a tethered reboot

  • Michamis1

    Hi there, is there any way to get a baseband of 4.10.01 for my iPhone 4? I’m using windows 7.
    Thanks

  • mssiddiqui

    Hello. I am currently on BB 6.15 and was wondering if I could update my iPhone 3GS to the official IPSW, as I am no longer in need of my unlock but would like to get better battery life from my phone. Some questions I had were if I was to upgrade, will the baseband get updated and if there will be any problems with my phone afterwards. Thank you in advance.

    • http://coolestguyplanettech.com Neil Gee

      Once you unlock and upgrade to BB 6.15 you can’t restore to stock IPSW it has to be custom.

      If you use the NO_BB iOS custom IPSW the 6.15 baseband stays as is.

  • GABRIEL BAGNASCO

    I have an Iphone4 (baseband 1.59). I followed every step all the way to at the very end where “You should see a bunch of scrolling code and then running pineapples – and its all happy days.
    5) After rebooting, launch Cydia on the iPhone, update, then tap the Cydia Search icon” 
    I saw the code running, the pinneaples, then the apple logo and finally the phone got stucked in the spinning gear…. I had to put it on recovery mode now but while I’m trying to restore using the BB custom file I get the following error “The Iphone could not be restored. An unknown error ocurred (1604)…)

    Any ideas ? PLease help

    Thanks

    • http://coolestguyplanettech.com Neil Gee

      the iphone got stuck at the spinning gear as it is a tethered boot -reboot the iphone – point redsn0w to the stock IPSW iOS5 – then in redsn0w – Go Extras > Just boot tethered right now

      • Anonymous

        Just FYI I was able to fix it, thanks for your support.

  • http://coolestguyplanettech.com Neil Gee

    redsn0w has a recovery fix in ‘extras’ – stock IPSW is the one that doesn’t start with BB – correct – point redsn0w to stock IPSW by going to ‘extras’ > Select IPSW > the navigate to iPhone2,1_5.0_9A334_Restore > then try the recovery fix

  • DCKane027

    Worked, thanks a ton

  • http://coolestguyplanettech.com Neil Gee

    you upgrade to iOS with custom IPSW then you re-jailbreak with redsn0w

  • http://coolestguyplanettech.com Neil Gee

    1 – you could revert back to iOS 4.4.3 as your baseband is untouched – I have a cutsom iOS 4.3.3 baseband preserving IPSW on another post if you need
    2 – the procedure will be OK to upgrade and unlock – new bootrom will mean a tethered boot
    3 – you can leave the simcard in

  • http://coolestguyplanettech.com Neil Gee

    should be untethered – however others even though have the numbers below 40 which indicates an untethered boot have had to boot tethered – so no 100% guarantee

    • Gsaddler97

      okay well thanks so much for all your help going to start the process then ill come back with my results THANKS!!

  • Paul Godard

    Hi Neil, and thank you for sharing this tutorial!
    I still have version OS 3.1.2 on my JailBroken iPhone 3GS.It is safe to follow your instructions in my case?

    • http://coolestguyplanettech.com Neil Gee

      yes it should be fine

  • http://coolestguyplanettech.com Neil Gee

    yes 5.16.02 is unlockable – you can install 06.15.00 bb with redsn0w – just remember that you may lose GPS capability

    • Ccalle

      Thanks Neil. I probably won’t risk it, since I might be stuck with an iPhone that will never have GPS. And the iPad bb won’t let me restore to an official firmware to start all over again.

      • http://coolestguyplanettech.com Neil Gee

        yes its a risk – I did it and have no issues with GPS but others have failed – hopefully the developers of redsn0w can figure it out soon

        • Ccalle

          What about sn0wbreeze 2.8b9 (and b10). They claim to have fixed the location issue for the 3GS with the iPad bb.

    • Dvb_pci

      Is BB 06.15.00 necessarily in order to unlock iPhone 3GS with IO5.01? Would Ultrasn0w unlock while preserving your old 05.15.04 BB? 

      • http://coolestguyplanettech.com Neil Gee

        BB 05.15.04 is not unlockable (for now) , so you would need 06.15

  • http://coolestguyplanettech.com Neil Gee

    sounds like a GPS issue – which is a problem with some 3GS iphones on 06.15.00 – it loses functionaltiy for some and not others – I know that the guys at iphone dev are aware of it – if it is terrible the only thing i can suggest is trying to reflash the baseband which may help but not guaranteed – theres a tutorial on the site

  • dr_admo

    I’ve got the NO_BB custom ipsw, and enter into DFU mode, when I option-shift click the restore in itunes 10.5 – it gives me an error “The software required for your iphone is not installed correctly. Please reinstall iTunes to install the required software”

    I have the most recent itunes 10.5, and an iphone 4 with ios 4.3.5

  • Robin

    I have a jailbroken iphone 3gs and unlocked (via ipad baseband) on IoS 4. If i do the first few steps but no jailbreak it will it still be unlocked so i can use different sim cards in without it being jailbroken. Would i be able to start it untethered 

    • http://coolestguyplanettech.com Neil Gee

      no – if you restore to custom IPSW then it will be unlocked – to unlock you need to jailbreak and install ultrasn0w

  • Sebasti_28

    hi neil, heard that redsnow 0.9.9.b8 ready for use to upgrade ios 5 to ios 5.0.1..Any tutorials/steps?

    • http://coolestguyplanettech.com Neil Gee

      hi sebasti, yes I know b8 is out but it is for the beta iOS 5.0.1 – thats OK for those who want to experiment with betas but I think it safer to wait for the official iOS from Apple and version of redsn0w that can make a custom IPSW of it

  • Andy_17

    hi neil, i followed all of your steps to install a custom ipsw on my iphone 3gs new bootroom. the first problem is that redsn0w will not accept the custom ipsw. the the phone keeps on rebooting to the start of the activation menu, the at the end it says to connect to itunes and itunes freezes until my phone reboots. can you please hlep? thanks

  • Roycofco

    Dear Neil,
    It failed to activate after I installed your custom IPSW. How to activate it?
    Thanks much.

    • http://coolestguyplanettech.com Neil Gee

      no your baseband would be preserved – as long as you restore to the custom IPSW – the baseband you have is currently unlockable

        Hi Neil  once again need your help…………. i upgraded my Iphone 3gs to ios5 it works gr8 but battery dies in just couple of hrs.  is it possible to downgrade from ios5 to 4.3.3  as it was before???  can it be solved my battery problem?????

        • http://coolestguyplanettech.com Neil Gee

          battery problems are addressed in the latest iOS 5.0.1 – but it is not jailbroken yet – I would imagine soon – you could downgrade if you have your 4.3.3 hashes/blobs saved

    i have iphone4 carrier locked activated and using gevey sim Iphone bb 2.10 ipsw 4.1 I need to upgrade to 4.3.3. After upgrading to 4.3.3 will the iphone gets locked again with carrier or can I use gevey sim directly

  • Kevinindenver

    Neil, I’ve used the custom IPSW to install iOS 5 on my 3gs and preserved my baseband (06.15.00).  I’m not actually bothered about jailbreaking – it’s retaining the unlock that’s important to me.  In this state – can I now use iTunes for iOS updates as normal, or do I have to jailbreak and update through Cydia to keep the unlock?  Many thanks, Kev.

    • http://coolestguyplanettech.com Neil Gee

      Hi Kev – once you restore to custom IPSW you need to avoid iTunes updates and instead restore to custom IPSW.

      WIth the unlock though – it only gets unlocked after you install ultrasn0w via Cydia effectively meaning it has to be jailbroken.

    Hi Neil, I came across a strange issue though I am very happy. It goes like this. I have 3GS with ios 4.3.3. and bb 6.15. I have in past used custom ipsw to update ios on my iphone because I have upgraded my iphone to ipad bb. Yesterday after coming across this webpage I have downloaded custom ios 5 ipsw and have installed on my iphone. When I have started my iphone after update it started as untethered and unlocked device. In other words I have not used jailbreak process. I was shoked and amazed to see that. I have tried restarting phone many times but it was starting as untethered. I was happy to see that.

    As per your blog my phone has old bootrom (below 40 figure) but as per other websites (cydia and others) my phone is new bootrom (I checked this through control panel>device settings etc.

    Anyway,  now I was wondering if I could update my iphone directly from itunes with ios 5.0.1 will it install successfully and will it update my 6.15 bb with 5.16 or so? If that works I am a happy man. Please do reply.

    • http://coolestguyplanettech.com Neil Gee

      since your iphone is old boot rom it should boot untethered – regards updating you’ll need to keep away from direct iTunes upgrades and stick to the custom restores as it just won’t work as you have installed the ipad baseband.

  • nbhide

  • Sharan

    Hey Neil.,well..i own an iPhone 3gs which is running on ios 4.3.3 and it was previously jailbreaked n unlocked using redsnow which then upgraded my baseband to 06.15.00(current BB)now i tried following ur steps line by line but while i try restoring thru itunes by clicking options and selecting the NO_BB file…it prompts this message “The iPhone “iPhone” could not be restored.This device isn’t eligible for the requested build”…well..coming to bootrom…the 4th n 5th digits in my SN is 0 n 3…which makes it 03rd week…What Do I Do now???

  • Paul Godard

    It went well up to 9, then I got the message “The iphone ipad could not be restored. This device isn’t eligible for the requested build.”
    The more info links to http://support.apple.com/kb/TS1275?locale=en_GB
    There is no gs.apple.com in the host file.
    What do you suggest?

    • http://coolestguyplanettech.com Neil Gee

      hi Paul – the error is generated by 3 potential issues the host file entry, using the latest iTunes and using the the correct IPSW file – so is your iTunes up to date?

      Other than that since u are using a 3GS the IPSW you should be restoring to is:
      NO_BB_iPhone2_1_5.0_9A334_Restore.ipsw

      • Rob

        Hey Neil. Got the same issue as Paul (upgrading a 3GS) and have checked everything: iTunes up to date, OSX up to date, edited the hosts file, the No BB ipsw is exactly as you state above but keep getting the ‘not eligible’ error. Baseband is 05.13.04-6.4_M3S2.
        Paul, I had to get out of restore mode and back to my old configuration so i could use my phone. To do this, I used Tiny Umbrella (download from http://thefirmwareumbrella.blogspot.com/). Once it’s installed, click ‘Fix Recovery’ and it should take you back to how the iPhone was previously. 

        Thanks for any help Neil!

        • http://coolestguyplanettech.com Neil Gee

          hi Rob – if you did edit the host file – did you reboot and try again?

    Hi, Neil I tried to update my iphone 3GS BB06.16 IOS 4.3.3 with old boot room to IOS 5 cutom, made with Redsn0w 0.9.9b8. I always get error 3194. My Itunes is version 10.5 (latest) and there is no entry for apple servers in my hosts file. Just for reference, I’m using MacOSX Lion 10.7.2. Is there any way to update it and JB unthetered? Thanks

    • http://coolestguyplanettech.com Neil Gee

      Hi JD – not at the moment Apple has stopped signing iOS5 you have to wait for a jailbreak on 5.0.1 – I’ll repost when its available

    Hi Neil, is there no way to install iOS5 without apple signing? i got the error 3194 too… If only i updated a few days earlier… :(

    • http://coolestguyplanettech.com Neil Gee

      no there is no way – they are tightening the usage of how the devices are signed – yes you have to do the jailbreak before the upgrade is out and from what I understand another iOS upgrade is due soon 5.0.2 as there are battery life issues which means no jailbreak until it is out.

    Hello Neil.

    I’m a total newbie in this iPhone stuff, as I just got my iPhone 4.I’m currently using Gevey SIM, and I want to unlock my iPhone 4 using redsn0w, and (if possible) I want to upgrade my system to iOS 5.0.1Now, I think I might have a problem – my Baseband (Modem Firmware) is 04.10.01 and I’m not sure if that presents a problem to redsn0w… If it does, is there any possibility to DOWNGRADE my Baseband to a redsn0w unlockable baseband?Thanks :)

  • Usman Anwar

    3GS running on 4.1 with BB 05.13.04. The Serial Number 4th & 5th digits are exactly 40. Is this old boot rom or newer one 

    • http://coolestguyplanettech.com Neil Gee

      it should be old – but unfortunately thats not a guaranteed answer – others have these numbers and turns out to be new boot rom

  • Fraz

    Hi Neil G,
    I am on 3GS(old bootrom), BB=5.12.01, iOS = 4.3
    Just today I was trying to upgrade to iOS 5 (custom IPSW, I am an unlocker) but I got the error 3194. I know 5.0.1 JB is already out but MuscleNerd said to stay away from that until the backward compatibility is made.
    I tried the tinyumbrella method and custom hosts file method but nothing helped with 3194. Am I doing something wrong or Apple is not signing 5.0? If apple is not signing why host file method and tinyumbrella method not working?
    Any help?

    • http://coolestguyplanettech.com Neil Gee

      different way of signing now implemented

        So is there any solution? What do you suggest?

  • Liven

    Hello Neil,Really impressed with such number of comments and your quick and valuable response to all of those.Now, I also want to try out the new 5.0 iOS. I have an already jailbreaked and unlocked iPhone 3GS, with ios 4.1 (8B117) and baseband 6.15.00unlocked with Cydia and ultrasn0w 1.2.4. The problem is that its looses the carrier very easily.Sometimes it is showing me the full network range available and on the other minute it shows me ‘No Service’.I miss important calls due to this.  And Second reason, i would like to use ios 5.0.So, Should I proceed with the above tutorial that you have mentioned. Just to confirm.Because i saw in yellow color the text shown on top of your post “Apple has stopped signing the iOS 5 firmware making a jailbreak impossible – if tried you will get restore errors like ’3194? or device not eligible for the requested build – but there will be a jailbreak to 5.0.1 soon.”It Wed 23.11.11 when you think 5.0.1 jailbreak will be available?Or should i proceed with 5.0?ThanksLiven.

    • http://coolestguyplanettech.com Neil Gee

      Hi Liven,
      Not a good idea to do the ios 5 jailbreak as it will not work – I have left the post published as I will update it when the time is right.

      No jailbreak for 5.0.1 and to be honest i think we will see 5.0.2 released before another jailbreak is possible as there are a number of user complaints on 5.0.1

      With your inconsistent carrier service – it may be the baseband – if at some stage you upgraded by accident to an official iTunes upgrade and then reverted to a custom restore sometimes that can have an adverse affect on the baseband and require a re-flash – there is a post on the site.

      If it isn’t too bad wait for the next jailbreak on ios5 and then see what the service is like before thinking about doing the flash.
      Cheers
      Neil

      Hi – No you can’t update at this point in time – you will have to wait until another jailbreak is available, Apple have closed the opportunity on iOS5, iOS5.0.1 i think is a temporary iOS, you will have to wait until iOS5.0.2

    Moder

    • http://coolestguyplanettech.com Neil Gee

      sn0wbreeze and redsn0w don’t play well together – I would wait for the dev team to release the next jailbreak, and then jailbreak it with redsn0w, it should be available shortly after Apple release 5.0.2
      the other thing is that your baseband might need to be flashed again – if you are sure it is definitely old boot rom – reflashing it might solve the problem – there is a post on the site.

  • Helena

    Hi Neil, I have downloaded the file from your link:

     Download the latest official Apple IPSW IOS 5 for your iPhone model:
    iPhone 3Gs”My phone is in the restore mode but I do not want to ‘restore factory settings & update to latest version’ in iTunes as my phone is jailbroken so I am trying to use redsnow. When trying to restore my iPhone 3GS from the downloaded file, I get the ‘not eligible’ message. Which version is safe to download / what would be eligible?

    • http://coolestguyplanettech.com Neil Gee

      Hi Helena – you cannot jailbreak iOS5 at the moment, you will have to wait until Apple release iOS 5.0.2

  • Dmissiris73

    hi there! i follow the procedure three times and i keep getting the message that my devise is not eligible!!!??? i saved my shah with tiny umbrella, uncheck the option with cydia hosts and same thing happens!! what can i do? i am with iPhone 4 on 4.3.3

    • http://coolestguyplanettech.com Neil Gee

      please read the first paragraph highlighted in yellow….

  • JJM

    So, if  I have this correctly, I cannot upgrade to iOS 5.0.1 from my jailbroken 3GS iPhone running 4.3.3 because Apple is not signing that firmware any longer? Secondly, if the untethered jailbreak for 5.0.1 comes out this week, will I be able to use the above steps to upgrade then jailbreak?

    • http://coolestguyplanettech.com Neil Gee

      First part correct

      Second question – the 5.0.1 jailbreak should have been out for now but i think we won’t see one until 5.0.2 is released – then there will be possibly a new redsn0w version and you will have to work from custom 5.0.2 ipsw files – the steps in the post will work but I will update the links when the jailbreak is available.

      will be ok to try now

    Hi Neil,
    I can tell a lot of people are confused by this article, it seems to be very misleading.  I have read it more than a few times now and I’m still not sure exactly what it is teaching us.  In plain english, please tell me what this tutorial accomplishes?

    The first paragraph says “at this point it is impossible to jailbreak iOS5.” 
    But then two paragraphs later you say “If you have previously jailbroken your iPhone, the only way to get to iOS 5 is from custom iOS IPSW…” And then you have a tutorial explaining how to update your jailbroken iPhone to iOS 5.

    GREAT! So I CAN update my jailbroken iPhone to iOS 5! Right? I mean that IS the headline of the article after all.  

    “Upgrade jailbroken iPhone to iOS 5″BUT WE CANT UPGRADE OUR JAILBROKEN IPHONES TO IOS5!! So what is the point of this article?  How to update your jailbroken iPhone to a non-jailbroken iOS5? How to jailbreak the future  5.0.2 update? Any clarification would be appreciated.

    • http://coolestguyplanettech.com Neil Gee

      It clearly says in the opening paragraph highlighted in glorious yellow that I will update the post when the next jailbreak is available.

      In plain English this tutorial has helped a lot of people jailbreak to iOS5 before Apple stopped signing and I will update it when appropriate.

      You may find that a lot of content on the web is out of date!

      If you are not happy then I suggest you move on.

    you after you use a custom BB to update to 5.0.1, the next time you update to install cydia it won’t update your BB automatically correct?  I just want to be extra sure.

    • http://coolestguyplanettech.com Neil Gee

      It won’t update your bb as along as you restore to the ‘NO_BB’ firmware

    hi, i had previously jailbroken my iphone from vodafone on to 3.. i wasn’t aware that by updating the software to ios 5 i would then deactivate the phone. Because of this, my phone has gone through the process of downloading the new software, however i am now at the stage where my iphone is displaying the message “activating phone this may take a few minutes” to “could not activate iphone, the activation server is temporarily down..”
    is there anyway i can get the screen on to the normal homescreen so i can jailbreak it back to a software that isn’t ios 5 or do i now have a shiny uselss brick?
    your hep would be greatly appreicated!

    Okay, so just to make sure of this Neil, after I follow the preserve basebands in the first section of the tutorial, and I upgrade to the NO_BB restore, when I do the second half of this section and do the re-jailbreak and SELECT IPSW stock firmware for this jailbreak, it will NOT upgrade my baseband, correct? Because I think it will if you’re selecting stock ipsw for the second half of this section.

    • http://coolestguyplanettech.com Neil Gee

      In the second half redsn0w needs the stock IPSW to create and install the jailbreak exploit it will not update the baseband –

      the critical thing is the NO_BB restore in the first half

    hi. I have JB iPhone 4 iOS 4.3.3 with 01.59.00 BB. Should I proceed with JB for iOS 5.0.1?
    What does it mean that official BB installed for iOS 5.0.1 for iPhone 4 is 04.11.08?

    • http://coolestguyplanettech.com Neil Gee

      Its just a note to state what the official basebands are if you had stock iOS but the process will retain your 01.59.00 BB

    Great work here.  Question:  iPhone 3Gs unlocked with jailbreak running on Tmobile.  Serial numbers 4-5 are sub-40, baseband is 3.1.3 and running sub version 4.0.  Prior to following the instruction above it is never mentioned to BACKUP all of you iPhone data to iTunes.  I reckon that’s obvious to do so, but just thought I’d ask.. should your iPhone be 100 percent backed up to iTunes…??  And, am I good to go iOS 5 with my 3Gs?
    thanks in advance…

    • http://coolestguyplanettech.com Neil Gee

      iTunes backs up devices when they are sync’ed

      Your baseband 3.1.3??

  • http://coolestguyplanettech.com Neil Gee

  • Gerardo A Hernandez

    Neil,  it worked fine my BB is intact. Now I need to change my APN settings to include my local carrier so internet works.  Where is the carrier plist file to edit it? Any suggestion?  I am using disk aid which allows me to see all the system files in the iPhone iOS5.0.1.  I need directions on how to edit the carrier file in order to include the local carrier for internet surfing on the iPhone….

    Your advise and direction is highly appreciate

    hi
    guys i am so confuse can u please help me
    i have iphone 4.0 already being jail broken now i want to update it with iOS 5.0.1.
    is this the process work and i can do the untether after doing tether by using conora new untether right

    • http://coolestguyplanettech.com Neil Gee

      don’t know about conora – the process should work fine

      • Ankitpatel2048

        thanks

  • Gerardo A Hernandez

    I did all what has been detailed step by step. But there was one more step I took further not included therein. In order to get the data services up and runing the APN had to be adjust by unlockit.nz website. I did and created the profile for a third party, local carrier.

    Next, I turned off the iPhone 4.  When I turned back on it stalled in the apple figure.How can it be pulled out to load everything and get it to work normally?

    Should I go back to the beginning and start the process from scratch?

    • http://coolestguyplanettech.com Neil Gee

      hi – I would start it again, I can’t comment on the unlock website they should be able to provide the process if you have paid for an unlock

    Hi Neil,
    I followed all steps and every thing went well (have iphone 4, modem firmware 03.10.01 don’t know is that the BB or not) but after the jailbreak all cydia apps were gone, tried to restore them but no way…my some missing phone no.s from my cantact list although i used to sync with itunes all the time…as for rebooting with redsn0w it went well for first two times but after that always troubles happening with reboot and now cydia safari mail not working even youtube freezes before playing the videos…need your help please

  • Cariad

    miraculously everything is now working again except the sim won’t work keeps coming up as no service any ideas

    • bok

      search for ultrasnow in cydia

  • http://coolestguyplanettech.com Neil Gee

    yes

  • http://coolestguyplanettech.com Neil Gee

    yes the process preserves the baseband

  • http://coolestguyplanettech.com Neil Gee

    yes you need to follow the whole process

    • Guest

      thanks for quick reply.
      while building custom ipsw, it gave me message that if its new boot rom then I will need SHSH blob?? 
      I can save SHSH using tiny umbrella, but not sure when and how to use it.

      Regards,

      • http://coolestguyplanettech.com Neil Gee

        you only need to the SHSH blobs if you have to revert back – they are a signed secure certificate for the device

  • http://coolestguyplanettech.com Neil Gee

    try the recovery fix under Extras in redsn0w

  • Jeffwiersema

    I can assure you it won’t. I just followed these steps. Baseband is the same. I am untheathered and loving it.

  • Melanie

     I tried all of the recovery fixes that I could find (iRecovery, TinyUmbrella… etc) and they didn’t work, but then I found another 5.0.1 custom ipsw by sn0wbreeze I believe and I used it instead with iReb to get rid of the 16XX errors and it worked (finally!!). Thanks!

  • Joe Edginton-Foy

    Hi Neail, 
    I have a 3GS jailbroken too 4.3.3 with boot 06.15.00 but i also use Ultrasnow to use a different carrier Originally on orange now Vodafone), will the first half of this post get me to IOS 5.0.1 and still allow me to use the different carrier? thanks. 

    • http://coolestguyplanettech.com Neil Gee

      yes when you restore to iOS5 just make sure it uses the ‘NO_BB…..’ firmware and your 06.15.00 will be maintained

      • Joe Edginton-Foy

        awesome! thank you!! oh and sorry for spelling the name wrong, typooo! 

  • http://coolestguyplanettech.com Neil Gee

    try again – make sure the iPhone goes properly into Pwned DFU mode – the screen is black if the iPhone has the iTunes logo then it is not in Pwned DFU

    also check that gs.apple.com is not blocked or redirected in your hosts file, put gs.apple.com in your browser and you should get a ’404′ page from Apple

    Hi.. I have an iphone 3gs.. it’s tethered jailbroken on ios5.0.1 and unlocked..

    beside this itunes says “can’t sync iphone because sync failed to start”..
    i think i’ve done something wrong while upgrading from ios4…so i think I should folow your guide from the top… you think this will help?
    and will i be able to unlock? (I am at 06.15.00 now)

    Hi…I have a jailbroken iPhone 3GS on ios4.0 (8A293) that I am trying to upgrade to a jailbroken ios5. I get as far as step 8 to updating the iPhone to ios5 but I keep getting an error 1601 or 1602. The restore has not done anything to the iPhone yet because I can exit dfu mode and my phone is okay. I have tried all the troubleshooting for the error but I cannot get past that point. Can anyone give me an idea as to what I am doing wrong or what I can try?
     
    Thank you

    Hi Neil,
    I have a jailbroken (tethered) Iphone 3GS running IOS 5.0 (9A334) new bootrom.
    can I upgrade it to IOS 5.0.1 just by using custom ipsw and then using itunes?

    I want to be sure because I have had a lot of problems with the device…

    Please reply!

    Thank you very much!!

    • http://coolestguyplanettech.com Neil Gee

      using the custom NO_BB restore IPSW through iTunes yes

        one last question before I can try it out: my iTunes is now version: 10.5.0.142
        It is not THE newest but is it essential to upgrade to the newest version of iTunes

        Tnanks for your aid and I hope it will work out!

    Hi Neil,

    I have JB iPhone4 with iOS 4.0 (8A293) Modem firmware – 01.59.00 (Jailbroke through Jailbreakme.com) and never did any updates further. Now I want to upgrade to iOS 5.0 or 5.0.1 and get rid of all Jailbreaking. Can I just use the normal Restore and then Upgrade to iOS5 process in iTunes OR should I do all the activities you have mentioned in your above post for upgrade. Your help is greatly appreciated on this.

    • http://coolestguyplanettech.com Neil Gee

      once you jailbreak you cannot use iTunes for normal upgrade you have to do the custom restore so you need to do at least the first half of the post and if you want to jailbreak and unlock then also do the second half

  • sixarm

    Thanks so much for this.

    I just followed the guide with the following device, 3GS, New Bootrom & 05.11.07 BB and it worked fine. The only issue I had was with signing.

    My TinyUmbrella failed for some reason (error 11 in iTunes), so I tried using Cydia servers via a hosts file, which also failed (error 1602 in iTunes), I guess their servers are pretty busy at the mo! So I ended up using Apple signing instead and that worked fine.

    All untethered, 5.0.1 on 05.11.07 BB. :)

    great tuto, i have been through it for the past few days and feel confident enough to try it.

    my iPhone is 3gs, version 4.3.3 (8J2), 4th & 5th is 16, modem firmware 06.15.00, it is jailbroken and unlocked to all networks.

    does anyone see any possible issues before i try it?

    i take it the most important thing is i don´t upgrade software through iTunes!

    thanks for any comments

    Hello and Happy New Year to everybody! I have the following situation that I believe is going to become common to everybody pretty soon: – Have an 3GS (bought it 2 years ago) from AT&T – Updated it to 5.0.1 via ITUNES – After that, it has been jailbreaked using redsn0w B3 – Current Firmware: 05.16.05 First problem: – Ultrasn0w didn’t work, since it is not yet available for my FW. – First Question – Any options to at this moment on how to unlock my 3GS IPHONE? Second problem or situation: – I just got a new 4S that I am not planning to jailbreak in the near future. – My idea is to transfer all email settings, photos and apps to the new 4S. – Delete all personal data from my 3GS and give to my dad (he doesn’t have ITUNES account or similar). Whats the situation here? He needs to create a new account ITUNES account? What will happend to Cydia? I am afraid to transfer my ITUNES account to the 4S, and then leave the 3GS inoperative (since the backup files are now linked to 4S). Thank you very much for your help!!!

    just upgraded 4.2.1 jailbroken iphone 4 GSM to 5.0.1!!! At first i got a message with itunes saying 1602 or 1601 error, this is easily fixed by deleting the last line that says gs and has an ip address, from the hosts file located at”C:WINDOWSsystem32driversetc”.
    everything else was done according to this tutorial!! thanks!!!

  • Plonker

    Hi Neil.  I have jailbroken my 3GS 5.0.1 with BB 6.15.00 intially using a Redsnow tethered JB and then using Corona to untether. It seems to be working, however, I am having a few problems with signal strength varying.  If I completely re-JB and unlock following your tutorial, will I need to re-install Cydia? Thank you.

    • http://coolestguyplanettech.com Neil Gee

      yes you would need to reinstall Cydia as a custom restore will take out the non-iOS stuff,
      also if your signal strength is varying and you have old boot rom you may consider re-flashing the baseband

      • Plonker

        Thanks for the advice Neil.  Unfortunately I have the new boot rom and I heard that flashing it will destroy GPS capability.  Have you heard of any other fixes for the signal strength issue? Thanks again for the advice.

          Yes don’t re-flash new boot rom – no sorry don’t know any other fixes for signal strength

  • Jbomb2395

    is it alright if i jailbreak my iphone4 using redsn0w without pointing it at the custom ipsw? I have iphone4 updated to ios 5.01, used redsn0w to preserve the baseband (4.10.01) however when i manually select the ipsw in redsn0w it says the ipsw it created is not supported. 
    Thanks for the help.

  • http://coolestguyplanettech.com Neil Gee

    no you don’t have to preserve the baseband if its factory unlocked

        in the post..

        • icemanvikoy

          im sorry Neil, what i mean is.. what method should i use?
          1. Live update from iTunes
          or
          2. Restore from stock 5.0.1 ipsw

          • http://coolestguyplanettech.com Neil Gee

            no worries – thought you were being a lazy bugger! –

            Anyway, neither method.

            The restore on a jailbroken iPhone has to be done from a custom restore, if you do it from stock or iTunes, it won’t work

      I have heard this occurs sometimes when the accidental upgrade to stock iOS is attempted and for old boot rom users then a reflash helps the stability of the baseband –

      Hi – maybe just unzip it and the resulting file should be .ipsw or use another browser to download that doesn’t zip it in the first place…

      • MAC

        THANKS, Rightly said chrome could detect as ipsw :)
        cheers man

    Hi

    After following all the above steps. when atlast my iphone is restored to newer version, the iphone is unable to search the netwrok.

    my iphone was unlocked 3gs and now i have upgraded to ios 5, and i think it is locked again.

    Can you please help and tell me what shall i do

    • Stev_Gerrard

      Just to add above this post that, the only step which i couldn perform is number 9 ”
      9) After rebooting, launch Cydia on the iPhone, the app will ask you what type of user you are and then download the lastest packages and upgrade when prompted, then …………..”

      Since there is no network availability , i am not able to get download the packages and install the ultrasn0w and reebot my device.

  • Clee2323

    how do i fix 1601 error? while restoring…  do i need to edit my host file?

  • Rajanv9

    Having error 3194? Please help what do i do? 

  • Lydia Elegante

    For whatever reason, my phone won’t come out of restore mode.  The upgrade was successful (as far as I know) but now I can’t turn my phone back on to do a restore from the previous back up…  Any suggestions??

  • Ramudada

    hi Neil,
    Thank you for this wonderful post. the steps are clear and concise and perfect. Just one suggestion regarding the restore step. Some of us might have some apps purchased from Cydia on their phones which won’t get copied over unless we jailbreak the phone later. you might want to add that as a note or a reminder in there. :) other than that, this is a really perfect guide so far. 

  • http://coolestguyplanettech.com Neil Gee

    what version of ultrasn0w? what baseband?

  • existenz

    Iphone 4, IOS 4.2.1, BB 01.59.00 updated to IOS 5.0.1, BB 01.59.00. Worked like a charm. Thanks!

  • dano26

    Hi Neil!
     Great tutorial! I did everything you said correctly but once I went to restore with the custom IPSW it says “firmware not compatible” … Any suggestions? Thanks for the help!

    • http://coolestguyplanettech.com Neil Gee

      check that you downloaded the right IPSW for your phone at the beginning

      • dano26

        Thanks for the quick response Neil! I will try that again. Just for reference, my phone is a Verizon CDMA, I am already jailbroken on iOS 4.2.8, and the bb is 1.0.06 . Is there any reason any of this would cause me trouble? Thanks again for your help! Been at this for days with no luck…

    Hi ! Im on New Boot Rom, checked it -359.3.2. 
    Im having iphone 3GS jailbroken n unlocked 4.0.1 with BB 05.13.04
    Can i use this to upgrade to IOS 5 ?

    • Ran

      Itunes 10.5.2 for mac didn’t work, It sent me an error 1600, but in Itunes for windows  worked like a charm. Iphone 3gs new bootrom, IOS 4.0.1, BB 05.13.04 updated to IOS 5.0.1, BB 05.13.04. Thanks!

  • Cluelessnewby

    On Step 8, I get this message, “The iPhone could not be restored because the firmware file is not compatible”  What does this mean and what is the solution?

    • Cluelessnewby

      And when I’m in the DFU Mode I get this: “Sorry, that isn’t supported yet on the 1st generation device”  I have the iPhone 3GS that was running on the 4.2.1  Now it no longer even recognizes the 4.2.1 firmware.  It’s as though it’s wiped clean of EVERYTHING!

  • Stev_Gerrard

    Hi Neil

    But i see imessage is not working now, when turn it

    Can you please suggest

    • Ramudada

      Hey, i am also having the same issue. any tips to fix this would be greatly appreciated. thanks! 

    • http://coolestguyplanettech.com Neil Gee

      you have to add a repo source in Cydia – http://repo.bingner.com – then in Cydia search and add SAM

  • Ajeet Bharti

    Please guide me if I can follow the same process for my iPhone 4 GSM, BB 4.10.01.

    I create the custom IPSW and when try to restore, after extracting the software, iTunes says error 3194. Googled a lot on this, changes the IP address of the ETC/hosts file on windows with admin privileges but it wont work.

    I am using a gevey sim to unlock which requires me to preserve the baseband.

    Please help, if you can.

  • paul

    This is a wonderful post but I have been ill so
     misread part of it and got into a right pickle – I saw the “3G” and thought it said iPhone where it said iPod. So I followed the instructions for the 3GS. Two iPhone 3G, two problems.First, I had my friend’s iPhone 3G, not unlocked or Jailbroken. Your intro says do an Apple upgrade then jailbreak. So it upgraded to 5.0.1 without problem but of course when I came to Jailbreak it redsnow won’t do it. Can I downgrade to 4.2.1? Or do we just have to wait for a Jailbreak for iPhone 3G?Second, my iPhone 3g, jailbroken and unlocked using redsnow. Following your instructions for 3GS, I managed to brick my phone. After three days’ mental anguish and constant googling and various failed restorations, downloaded this custom ipsw - sn0wbreeze_iPhone 3G-4.2.1.ipsw – from someone  somewhere and installed it using the copy of redsnow I used originally to jailbreak, not the current one. And, lo, it worked! Now I am jailbroken and unlocked on 4.2.1, just like before. Is there an upgrade path for me at the moment to 5.0.1? It is so much quicker than 4.2.1.Again, thanks for this wonderful post. If you could somehow make it clearer to morons like me that iPhone 3G does not equal iPod 3G it would be perfect.

  • http://coolestguyplanettech.com Neil Gee

    Hi, well redsn0w will activate the iphone and ultrasn0w will unlock and if it unlocks then you can use any carrier – but you better quote your baseband first

    • Anonymous

      Hi Neil.  I’ve done everything EXCEPT that it continues to SEARCH for a carrier for a while then goes to NO SERVICE.  Plus it says that I have no SIM card inserted.  The SIM is inserted. Help!  I do recall when CYDIA was installing with the black screen and prompts, it did say something about not being able to locate the BASEBAND.

      • http://coolestguyplanettech.com Neil Gee

        what is the baseband version and is ultrasn0w installed

  • http://coolestguyplanettech.com Neil Gee

    best check the downloaded firmware matches the iphone, whats the iphone type and whats the name of the firmware you downloaded?

  • http://coolestguyplanettech.com Neil Gee

    hi Diana – try the recovery fix in Tiny Umbrella

    that doesn’t sound right, did you use the latest version of redsn0w as linked in the post

    Hi, So I have a jailedbreak 3GS iphone using tmobile service and my boot-rom is 43 and my baseband is 05.11.07.  Everything worked until the activation of the iphone.. it says “SIM not valid”  “Only compatible SIM cards from a supported carrier may be used to activate iphone.  please insert the sim card that came with your iphone or visit a supported carrier’s store to receive a replacement sim card.”  Is there any way to fix this?  Thanks in advance!

    Hi, I have an iPhone 3GS new bootrom (iBoot 359.3.2) BB 5.13.04 jailbroken (via limera1n) and unlocked on iOS 4.0.2. I went to cook myself a custom IPSW in redsn0w 0.9.10b3 and when it asked which bootrom of 3GS I was on, it also contained a warning that for a new bootrom phone SHSH blobs would be required in order to restore to the firmware. Since I got my phone after Apple had stopped signing 4.0.2 I have no saved blobs. Am I out of luck upgrading to 5.0.1 and keeping my BB or is there a way to do this without blobs on a new bootrom 3GS? I haven’t gone ahead to try flashing the cooked IPSW yet because I don’t want to do something foolish! Thanks for your time and this excellent article.

    • http://coolestguyplanettech.com Neil Gee

      A restore to iOS 4.1 is still possible as Apple is still signing this for iPhone 3GS only, you could download the official stock iOS 4.1 and restore via iTunes

      • cmk

        I thought that 4.1 would update the baseband to something not presently unlockable?  Is that not the case? I was thinking of trying iFaith on an old Windows box of mine to save unsigned blobs, anyone had any experience with this?

  • Sharadpande

    Thanks Neil for the detailed post. Was able to successfully upgrade my iphone 3gs on ios3 to ios 5. Mine was already jailbroken and i am using it with a local carrier in India. Was lucky enough to have retained the original AT&T SIM which was required to restore the data from back in itunes after the ios upgrade. Without this i would have been stuck. You might want to include the requirement of original SIM information in the details or suggest if there is an alternative to that.
    But anyways thanks a lot for the details article. Will start using the ph with ios 5 and let you if there are any issues.

  • http://coolestguyplanettech.com Neil Gee

    you need to make sure you have your SHSH blobs are saved, either on Cydia or use Tiny Umbrella, once you know that these are saved then you will be able to restore to the previous iOS

  • http://coolestguyplanettech.com Neil Gee

    if you mean update the baseband to 06.15.00 iPad baseband only do it if you have old boot rom – http://coolestguyplanettech.com/how-to-find-out-which-boot-rom-am-i-old-or-new-for-iphone-3gs/

    you may have chosen that you have old boot rom when you have new boot rom – try from the beginning answering the correct boot rom question in the steps

  • http://coolestguyplanettech.com Neil Gee
  • riley

    This worked like a charm! I was a bit doubtful halfway through because iOS said that it could not activate the phone but the jailbreak fixed that though :P
    The only thing that sucks is that while I did back up the phone, I did not sync the apps, so all the apps are gone :/
    Nevertheless, you are a genius!! Thanks a ton :D

  • http://coolestguyplanettech.com Neil Gee

    plug the USB cable into a different USB port – see what happens…

  • Oucj0311

    Went through the whole process and had to use BB 16.15.00 on my 3gs and it worked perfectly. Everything was fine until I plugged in my phone and opened redsnow again and it went to a white screen and can’t get it out of there. Anytime I try the process over or anything I have no luck and it skips the DUF mode saying that I am in it. I think it might be stuck in a loop or something but I don’t know how to fix it. (Running the newest ios). Please email me if you have any solutions to this.

  • http://coolestguyplanettech.com Neil Gee
  • http://coolestguyplanettech.com Neil Gee

    should be ok, follow the process including re-jailbreak and unlocking

    baseband cant be downgraded only upgraded – there is always a risk? you do so at your own choice, there are obscure errors that happen to some and others have no issues at all…

  • J. Gregory Edwards

    Great tutorial! Thank you! I successfully jailbreaked and preserved the unlock on a 3GS that was running iOS 4.0. I only have one issue: the iPhone will not load any of the cracked apps that were working before. They are recognized in iTunes, and they attempt to sync, but ultimately they fail. Any advice? Thank you very, very much.

    • http://coolestguyplanettech.com Neil Gee

      i think you will have to get those via Cydia

  • Ram Bhadoriya

    After rebooting, connect thru wifi – launch Cydia on the iPhone, the app will ask you what type of user you are and then download the lastest packages and upgrade when prompted, then tap the Cydia Search icon (bottom right) and tap in ultrasn0w, Cydia finds the package and then install ultrasn0w 1.2.5 and reboot the iPhone this will complete the jailbreak and unlock the device. will show you network

  • Hassib

    Hi Neil, 

    I have jailbroken the phone but I receive no signal anymore. It searches and then simply says no service. I have been working on this for 2 days. Please help. 
    I thank you in advance. 

    • http://coolestguyplanettech.com Neil Gee

      is cydia/ultrasnow installed? What is the iphone type and baseband version?

      • Hassib

        Yes it is. iPhone 4 and 04.10.01

        • http://coolestguyplanettech.com Neil Gee

          that baseband is not unlockable, are you using the original carrier sim card that came when the phone was purchased?

          • Hassib

            I have a Gevy if that makes any difference. I am not using the original sim card. 

            If I have no choice, is it possible to revert back to a previous version and get it working again? 

          • http://coolestguyplanettech.com Neil Gee

            it makes a big difference – you’ll have to find out from the Gevy people how it would work, if you have your SHSH blobs saved you can revert back – you need to search on Gevy solutions for iOS 5.0.1

          • Hassib

            Neil…. Thank you very much. You are insanely helpful. I will look into it.

    Redsn0w says IPSW for IPhone 3 and won’t let me use it for iPhone 4.2.8

    • http://coolestguyplanettech.com Neil Gee

      sorry I don’t understand what you mean

  • Samanosuke

    I am currently in the process of updating my jailbroken iphone 3gs to 5.0.1. I installed the custom ipsw that redsnow made to itunes, but I’m just wondering how do you restore with the latest itunes backup? My iphone is still in dfu mode btw

    • http://coolestguyplanettech.com Neil Gee

      itunes restore backup occurs after the custom iOS restore – you will need to have sync’ed the iphone prior to the whole thing to make the backup up to date

      • Samanosuke

        I did follow the instructions to sync before updating, but after the custom ipsw is finished installing, instead of going to the “itunes restore backup” screen, a message in itunes pops up and says “it detects a device in recovery mode”. When I tried to restore it again using the custom ipsw, I get the “1600″ error code which apparently means I need to go into “pwn dfu” mode. I do so with redsn0w and attempt to restore with the custom ipsw…again. It does the same thing by installing all the way through, but itunes doesn’t give me the option to restore from backup. Please help with the problem. I’ve looked everywhere on the internet with no results.

        • http://coolestguyplanettech.com Neil Gee

          it sounds like you are not going into the correct ‘pwned dfu mode’ at the beginning before the custom IPSW restore – that is why iTunes thinks its in a recovery mode.

          pwned dfu mode results in a pure black screen on the iphone – is this happening

          • Samanosuke

            …also used iReb to put the iphone back into dfu. It says I’m in DFU, but the screen is not pitch black although if I restored with the custom ipsw it goes through it’s cycle again but itunes still detects the device in recovery mode. I think at this point I rendered most “Exit recovery mode” programs useless(iReb, tinyumbrella and so on)…giving you as much information as I can at the moment. Thx for the assist btw.

          • Samanosuke

            Restarted my computer, entered pwn dfu mode with Redsn0w, then made a new custom ipsw (I found out my device was a new bootrom instead of an old bootrom.) Installation worked perfectly and I am currently syncing all of my data…on to jailbreaking I guess. Thx for the help m8!

          • Samanosuke

            Checked the control panel as well. It says “Apple Recovery (DFU) USB Driver”. I guess it must be in DFU then. Any suggestions on what I should do?

          • http://coolestguyplanettech.com Neil Gee

            see the thing is it is not in ‘pwned dfu’ it is in regular ‘dfu’ – use redsn0w Extras to exit recovery

    My baseband?

    • http://coolestguyplanettech.com Neil Gee

      well if the iphone is still with the original carrier then your baseband doesn’t need to be unlocked – so you can just jailbreak and all will be ok as long as you are happy staying with the original carrier

    fix or exit redsn0w also has recovery fix, the iphone did not enter pwnd dfu mode – it entered regular dfu mode

    • http://twitter.com/neo1piv014 Isaac VanHaverbeke

      I’ve got the same problem. RedSn0w said I was in pwnd dfu mode, I ran the update, and everything seemed fine. Then my phone just got stuck on a solid black screen, and FIx Recovery doesn’t do anything. 

  • http://coolestguyplanettech.com Neil Gee

    exit recovery and try again – the iphone must enter pwned dfu mode correctly

    • iPhone 3GS owner

      i have tried many times to get out of dfu mode using redsn0w, it gives me this

      The IPSW for the following build is needed: iPhone2,1_5.0.1_9A404
      The required IPSW is either not public or not available right now. Please provide it manually using “Extras-Select IPSW”
      Note: If you provide this IPSW once, it will be cached so that you don´t need to provide it again.

      the one i downloaded from above link is iPhone2,1_5.0.1_9A405_Restore

    name of …setup,ios diagnosis,sheet…when i restart it disappear when
    i install an other it comes again…an i restore 2 times but still
    happening.can any one help me

  • Tomsiphone

    It worked great for me.  Just a hint…this phone (3GS, old bootrom) has a little “quirk” in that it takes three tries before iTunes will restore the custom ISPW. 

    On the first try, it goes through the extraction process and says it is restoring the software.  After about 5 minutes, it pops-up an error 1601 (i think).  All I do is exit iTunes, wait 5 secs and start iTunes again.  I do nothing to or with the phone.

    On the second try, it goes through the same process, then lights the screen on the 3GS and then waits another 5 minutes and gives me the same error.  Again, I just exit iTunes and restart it.

    The third time is always the charm and everything happens like it should.

    If you are having the same kind of fun, try this and see if it works.  Otherwise, redsn0w worked as is should.  I was JB’d on sn0wbreeze but I had too many issues with it.

        I used redsnow instead of pawange tool and it worked flawlessly I now have my iPhone 4 with IOS 5.01 and BB 1.59GREAT!

  • http://coolestguyplanettech.com Neil Gee

    Hi, you are not doing it right – that message happens if you select a custom IPSW “NO_BB….” from the redsn0w menu “Select IPSW”…..check the tutorial again

    • Ruby

      Thank you! Although now it says its unable to parse =[ 

    • Ruby

      Seems like whichever route I take, it leads to an error. 

      I did the “Select IPSW” 

      and the custom. Neither works

      thanks again!

    Hi, how to get back to 4.3.3 from 5.0.1. i have SHSH blobs saved from iSHSHit. Thanks.

  • G.S.

    Just wanted to say thank you. I’ve been meaning to do this for a long time, but been too afraid of bricking my phone. Your instructions made it super simple. My only moment of fear was when I could not restore my phone after the part 1 of the instructions. I crossed my fingers and hoped I could do it after part 2, which I could.

  • Tomsiphone

    Hi Ruby…no, I’m using firmware 5.11.07.  I’ve always preserved the baseband since I was on iOS v3.1.2. as I do a lot of traveling and use local carriers when I’m overseas.

    One day I’ll get it factory unlocked but then I would miss all this fun! :)

    I have a jailbroken ipod 3 running ver. 3.13. I downloaded this file “iPod3,1_5.0.1_9A405_Restore.ipsw”  Following your tutorial when I pick “custom ipsw” it tells me this option can only be used for iphone3 or iphone4.
    Not sure if it matters but it was jailbroken using Spirit like 2 years ago.
    Can you help please?

    The official basebands installed for iOS5 are:
    iPhone 3Gs = 05.16.05
    iPhone 4 = 04.11.08
    Neil, does this mean that I can’t do this update without losing my unlock? I’m using t-mobile phone service.

    • http://coolestguyplanettech.com Neil Gee

      no it doesn’t mean that, they are just listed as to what the official iOS 5 basebands you won’t lose your unlock if you use the NO_BB preserved custom IPSW as in the tutorial

  • Anonymous

    Hi Niel,

    I’ve got an iPhone 4(4.3.3) that is factory unlocked from UK & I’m currently using the phone in India. I recently Jailbroke it & I would like to restore & upgrade to iOS 5.
    I heard that by upgrading to iOS 5 the phone would go back to it’s previous locked state or worse get bricked.

    So, do I just follow the procedures here or is there any other way to go about?

    • http://coolestguyplanettech.com Neil Gee

      If you are sure it is 100% factory unlocked, it should be OK as there would never have been a previous locked state

    Hi Neil, Good job! i did like u have mentioned. Got it done perfectly. But jus one thing, whenever i use location service like maps, i loose the signal. Any suggestion? Thanks

             i cant install ultrasn0w cos i cant access the data on my sim, except i get a wireless connection. wireless are not so popular here…so this might take a while b4 i get it done. thx 

          • Lola

            my baseband is 06.15.00

  • Lola

    No. Ultrasn0w, I couldn’t install that cos I can’t access my sim. The baseband is 06.15.00 now pls what do I do now cos the phone is working fine except for ‘no service”

    • http://coolestguyplanettech.com Neil Gee

      you have to install ultrasn0w to unlock it, install via Cydia as in the post

    • antique

      you don’t need supported sim card .. jailbreaking with redsnow will pass the need of supported sim card… so just jailbreak it.

  • http://twitter.com/neo1piv014 Isaac VanHaverbeke

    So I followed all instructions to the letter, and now my 3GS is stuck on a black screen. I’ve tried the Fix Recovery button in RedSnow, and on the rare times when it does actually see that my phone is connected (and doesn’t crash) it loads something, says “Please Wait…” for about 10 minutes, and then goes right back to the black screen. I can’t do a restore in iTunes as I get errors 1600, 1601, and 1602. I tried exiting recovery with Tiny Umbrella, and I did get some different text on the screen, but nothing so far has allowed me to boot or even run a recovery. As it stands now, my phone is a complete brick. Yes, I checked my serial number to verify which bootrom I should use. Yes, I updated iTunes and got the latest RedSn0w. So far, nothing works, and I’d really like to have my phone back.

  • Guest

    This “tutorial” if you will, made me feel like a *rockstar*. I followed the instructions to the “T” and everything worked out as stated. I did, however, run into a minor complication with step 9  of the upgrade to iOS 5 portion – it wasn’t working as it stated it should, so I bypassed that step and pressed forward and all worked out just fine. 

    Kudos to COOLEST GUY ON THE PLANT!

    Hi, I have an Iphone 4 , running on 4.0.2   and baseband 1.59.00 . I have never done any jailbreak or unlock, but this tutorial seem simple, I know the current ios is 5.0.1 which is what I want to upgrade to, here is My question:  being that I am in an old baseband that happens to be unlockable, Can I upgrade creating a custom ipsw as shown, and just simply install ultra snow and unlock it? This tutorail talks about 3gs, so I am a bit confused. Also I do not have any shsh files, but as I understand the only way to get them is to restore with itunes which will make my baseband current, and unlockable, ( i think). SO when I upgrade with the custom ispw , will I get a shsh file without problems,to save with tiny umbrella  being that 5.0.1 the current version even though my baseband will remain 1.59.00? Can you only create a custom ispw, when apple signs it? or can you always upgrade with the custom ispw, and only need shsh files to downgrade?   Thanks for the help in advance.

    • http://coolestguyplanettech.com Neil Gee

      – Guide is also for iphone 4
      - yes upgrade as shown and unlock with ultrasn0w, you have the only unlockable baseband for iphone 4
      - your 5.0.1 SHSH files will be saved on Cydia server you can also save with Tiny Umbrella
      - you can only create a custom IPSW when the dev team releases capable software
      - once you jailbreak you can only upgrade through custom IPSW to maintain the unlock
      - most important part is when you restore the phone to use the made NO_BB custom IPSW which preserves your baseband to 1.59.00

    got a question neil… or to anyone who knows, i want to follow tha steps provided above but first… i have an iphone 3gs jailbroken with redsnow and its latest version is 4.3.3 and i want to update it to ios 5.0.1… i downloaded the firmware and updating itunes to latest version… while doing tha steps above will i lose whatevers on my iphone already like photos, music and the apps downloaded from cydia n installous? following the steps above will i have to clear my phone, or it will be fine? thank you

    • http://coolestguyplanettech.com Neil Gee

      you will lose everything on the iphone as it restores to a brand new iOS original operating system only, but then you restore all your data from iTunes, all the apps via Cydia will have to be re-downloaded via Cydia – before you do the process make sure you sync the iPhone or to be extra cautious do a full back up

    I just went through the entire process soup to nuts with my 3GS with 4.2.1 baseband 6.15.00 and it worked like a champ.  No issues what so ever.  Thanks Neil.  For those seeing the “no service” with the sim after running ultrasn0w, be sure to reboot the phone.  Just restarting the springboard won’t get the new SIM recognized.  After rebooting it took about 3 nervous minutes, but then it found the signal and all is well.

    Is it possible to jailbreak and unlock an iPhone 3GS with the following:

    OS: 4.3.5 (8L1)
    Model: MC131B
    Serial No: 82005******
    Firmware: 05.16.02

    Never jailbroken, never unlocked (I NEED it unlocked!)

    Could I use this tutorial to do it? Could I upgrade to OS 5?

    • http://coolestguyplanettech.com Neil Gee

      on your current firmware 05.16.02 jailbreak=yes unlock=no

      possible to upgrade firmware to 06.15.00 if boot rom is old – then can be unlocked

      • Odarrien

        How do I know if the boot rom is old and upgradeable?

        • http://coolestguyplanettech.com Neil Gee

          I have a post on how do do that

          • Odarrien

            Ok I found the post.  Under the tag “Device Instance Path”, the end of the value says [IBOOT-359.3.2].  So I therefore have the new boot rom *sigh*.

            Do I have any hope in unlocking this phone at all?  Is there a way to upgrade to a firmware which can be unlocked even with the new boot rom?

          • http://coolestguyplanettech.com Neil Gee

            No not at this point, you could upgrade the firmware to 06.15.00 but you stand a chance to lose the GPS function – otherwise you have to wait until the newer basebands are unlocked by the dev team

          • Odarrien

            *groans*  so disappointing.  I’ve had this phone 6 months now hoping for an unlock…..

            Thanks for all your help Neil.  I’d keep an ear out for when the dev team unlock the newer basebands.  

            So should I upgrade to iSO5 in the meantime or is it best to just stay with everything as is until a newer baseband is unlocked?

          • http://coolestguyplanettech.com Neil Gee

            I would stay until other basebands are unlocked

    I’ve been this for a half-day… did everything… read carefully… I’m so exhausted… I’m tears fell because of failure… I wish I never ever even thought of upgrading to iOS 5.0.1… I should have stuck on iOS 4.1.1… my life wouldn’t have been this miserable… I never shouldn’t have use the iPad whatever option that was… NEVER got my SERVICE back……………………….

Couple days ago I did step-by-step your tutorial and my iphone 3gs baseband 6.15.00 ios 3.2 successfully updated to 5.0.1, then eventually i ACCIDENTALLY restore it using itunes… after that the nightmare had begun. I lost my service, then I tried your tutorial again but no progress I still havn’t service even after ultrasn0w had been installed and rebooting my iphone.
    my firmware is still 6.15.00
    sn 88112***
    ios 5.0.1 (9a405)
    iccid no sim
    carrier not available
    wi-fi does working
    Please help – 2 days without a phone((((

    • http://coolestguyplanettech.com Neil Gee

      since you tried to restore via iTunes you have made your firmware unstable – if the iphone is old boot rom, you will need to reflash it – http://coolestguyplanettech.com/re-flashing-the-06-15-00-iphone-3gs-baseband/

      • Alex

        Thanks for quick reply!
        If I do so will I be able to downgrade ios then?
        And is there is any chance that in a close future this unstable firmware will be able to unlock?(cause I kinda afraid of the warning message etc)
        btw what is the difference between baseband I previously had and ipad one?

    • Raj

      Download IfunBox and also download ultrasnow.deb and mobile substrate.deb file for your iphone and drag them into cydia app.

      Your network will start working

    Hi Neil,

    I am at the “hacktivate” phase of the process and my phone went into an Itunes induced recovery mode. The phone is a hacked 3GS now operating on OS 5.0.1 with modem firmware maintained at 5.13.04. The phone is not allowing communication with Redsnow anymore and I have since restored it again using my NO_BB_ ISWP and I think communication is restored between my phone and computer (haven’t tested it yet outside Itunes but appears to be “restored”. My Question is should I try the hacktivate again or should I use the “Recovery Fix” first?

    Many Thanks!

    Cheers!

    Hi My son gave me his old 3G iphone and I had it unlocked (jailbreaked, a term I had not heard of) at a cost of £25 (did not realise it could be done by o2 free) then my problems started they did not warn me about updating on itunes so when I clicked on it automatically started updating, got near the end and locked my phone with the picture of itunes with the cord pointing to it.  The guru at o2 managed to get the phone working again but with the low version 3.1.1 so most of the apps I purchased and want to download will not load.  My question is this will this work on my ‘jailbreaked’ and later o2/apple unlocked iphone. Which I guess didn’t matter.

    Hi Neil,

    I love your site and appreciate your sharing your expertise!

    I have an iPhone 3GS, Jailbroken and unlocked with the following system info:
    Version 4.0.1(8A306)Serial Number xxx21…, but-  IBOOT-359.3.2
    Firmware: 05.13.04

    2 quick questions:
    - Can it be upgraded to 5.0.1, and still be jailbroken AND unlocked (unlock is very important to me)?

    - Should I go by the “21″(older boot rom), or the 359.3.2 (newer boot rom) in redsn0w?

    I thank you again for your time and kind reply.

    Hi Neil,

    I’ve managed to install an jailbreak iOS 5 on my 3GS with. 06.15.00 firmware. I’ve installed ultrasnow to unlock it but it says no service or searching, however it does show up in settings>about that the carrier is now O2 rather than orange and most of the time shows a big long number in the ICCD section but sometimes shows no sim instead.

    Any ideas? This is my old phone which I want to give to my wife, we did pay someone to unlock it but they took it back to ios 4.1 and I found this guide and thought I’d do it myself for her but I now am running the risk of looking like a wally to her!

    Thanks in advance,

    i have my friends old iphone 3gs which was jailbroken but not unlocked and now after being pressured by many decided to upgrade the software since it never had been done and now i can’t set it up as it won’t connect to my itunes it says ‘there is no SIM card installed in the iPhone you are attempting to activate’.
    How does my sim card not work now? I had nothing saved!
    Any help would be appreciated.

  • lily

    ok i have done everything there is to do in the whole process of unlocking it and updating but now it has not found my server and come up with searching or sos only so what come do please help

    • http://coolestguyplanettech.com Neil Gee

      what is your baseband

      • lily

        its 05.16.05 but before the update it was different so what can i do i realised that it cant work but is there another way to jailbreak and unlock it again? please help!

        • http://coolestguyplanettech.com Neil Gee

          you have not preserved your original baseband, it seems you have restored to stock iOS 5 and upgraded the baseband which is currently unlockable

  • http://coolestguyplanettech.com Neil Gee

    your baseband is cannot be unlocked – only can be used with original carrier – if you still use the original carrier then it will be OK, if you don’t it won’t be OK

    • http://twitter.com/mhs619 Mehedi Hassan Shaon

       what do you mean by original carrier!! is it mean that the SIM was used during activating the phone for the first time???
      if it is so then i guess i am not using the original carrier!! is there any way to unlock or solve it???

      thank you for your reply….

  • AGH

    I have a 3GS, baseband 06.15.00 and iOS 5.0.1 already installed in it when I got it. Jailbroken and unlocked. This phone was supposedly working until it had some battery problems that I fixed. After I fixed the battery, I restored the phone with iTunes  (it was already on 5.0.1), Jailbroked with redsn0w and unlocked with ultrasn0w. I get a “searching…” followed by a “no service” message. I never get any signal. The ICCD and carrier are recognized from the sim.

    I tried restoring the baseband as was suggested to another poster and then reinstalling iOS without touching the baseband as suggested on this page, but the result is always the same.

    Now, I’m suspecting it might be the antenna or something, since the last owner told me that he got the same “no service” message a couple of days before the phone died, without updating the software.

    Is there a definite way of knowing if this might be an antenna problem or an unlocking problem?, any way of knowing that the phone is supposedly working fine with the unlocking procedure and it just doesn’t get a signal because the antenna is bad?

    Thanks.

    • http://coolestguyplanettech.com Neil Gee

      have you tried another carrier/sim

    • Nba-311

      Your lucky because you have to take an easy step now, you dont need all that restoring or checking if something is wrong with the antenna..
      Here’s what you do…
      1- Open Cydia
      2-Search Up For Ultrasnow
      3-Install it

      And thats prettie much all :)

  • http://coolestguyplanettech.com Neil Gee

    looking good

  • http://coolestguyplanettech.com Neil Gee

    should be OK

  • http://coolestguyplanettech.com Neil Gee

    as long as your baseband is unlockable or t-mobile is original carrier

  • http://coolestguyplanettech.com Neil Gee

    what is the baseband? is ultras0w installed

  • screwedOR?

    Please Help!

    I followed these steps. I was jailbroken and unlocked, with the 06.15.00 baseband. When it goes to restore in iTunes, it goes through all the steps and then says that it needs to be restored again. If I do it again, then i get the 1600 error. I have Lion now, and there is no etc folder ~
    Not sure what to do.

    • http://coolestguyplanettech.com Neil Gee

      there is an /etc folder it is just hidden – to access it go to the Finder then the Go menu > Go to Folder…. enter /etc

    I got two problems…after i restored, i couldn’t get my phone out of DFU mode….So i just went ahead, skipped the back-up step and proceeded to jailbreak it. But now (the second problem) redsnow is telling me that my phone doesn’t support untethered options….and my phone is an older 3gs :( please help

    Hi Neil,

    I have iphone 3GS jailbroken with BlackRa1n geohot, my cydia is doe not work anymore at all. I dont use any perks from jailbreaking anymore and want to use newer apps which need a higher update to install. I am a tech savvy person and your help would

    BlackRa1n

    3.1.2 (7D11)
    boot-rom : 359.3.2

  • http://coolestguyplanettech.com Neil Gee

    which iphone model and is ultrasn0w installed

    • Abraham samson

      its a 3gs.
      could not install ultrasn0w on the phone since at step 7 – the phone refuses to go into the dfu mode (on pressing the key sequence the phone always starts up and i don’t get a black screen) - so cannot proceed to install cydia

      • http://coolestguyplanettech.com Neil Gee

        make sure you are using redsn0w to get into pwned dfu mode

  • http://coolestguyplanettech.com Neil Gee

    just try a few times

  • Canaryoctave

    Hello,

    My iPhone 3GS is on new boot rom. Does this mean I will have to “just boot tethered right now” everytime I boot to be in jailbroken state? This is my last concern before I can proceed with jailbreaking it. 

    • http://coolestguyplanettech.com Neil Gee

      the current jailbreak allows for an untethered jailbreak so you don’t need redsn0w to boot the iPhone

    anyone whos phone doesnt work after 5.0.1 update via itunes its an apple fault and having spoke to them they say “older” iphones will not support the software causing it to crash…they then offer a replacement handset for £150!!! big scam dont update if your phones out of warranty  report to watchdog lots of people are and you never no they mite sort something out and accept liability the scamming ***************

  • Danish Afridi

    I stuck at step 8; iTunes extracts the software  and preps the iphone for restore, verifies the restore, restores the firmware and then does not restart iPhone 3GS (Previous base band was 6.15.0)
    I tried exit recovery from redsnow but it says exploit fail or some time say you need official firmware by selecting extras

    Looking for help

    • Danish Afridi

      after all my problem is solved. :)

      Guys triple check that you have new or old boot rom, however my iPhone 3G S  4th & 5th serial number digits are below 40 but i have a new boot rom that is causing the main problem (hats off to jailbreakqa as well)

      Enjoying iOS 5.0.1 + Unlock + Jailbreak!

  • Canaryoctave

    Hello,

    I jailbroke my iPhone according to the steps above and I managed to finish all the steps successfully. However, I’m getting No Service/Searching on my iPhone. I have just noticed that my baseband when I jailbroke my 3GS was 05.16.05, which like you said “not currently unlockable”. Is there a way to revert this error? Will restore to factory settings help?

    Thank you.

    • http://coolestguyplanettech.com Neil Gee

      seems like you didn’t use the NO_BB file as your baseband has not been preserved, you cannot revert, the only possible solution is to upgrade to 06.15.00 if you have old 3GS – you need to use guides on the site to find out which boot tom you are then if you have old boot rom, look at flashing baseband to 06.15.00

      • Canaryoctave

        I’m sorry but what is the NO_BB file that mentioned? What is its function? 

        I’ve done some research and it says that I should check “install cydia” and “install iPad Baseband” if my baseband isn’t unlockable. I see that I had failed to notice that I should also check “install iPad Baseband” to get to 06.15.00 during jailbreaking. 

        For your information, I have new boot room. Does flashing baseband to 06.15 also applicable for this? If not, is there any other way?

        Help needed.

        Thank you.

        • http://coolestguyplanettech.com Neil Gee

          The NO_BB guide is clearly stated in the guide – it looks like you didn’y follow the process at all – if you have new boot room upgrading to 06.15.00 will likely kill the GPS – this is all clearly mentioned in the other guide.
          Looks like you are stuck until a way is found to unlock the new baseband.

          • Canaryoctave

            Hello again,

            I just read the upper half of the instructions IN FULL. Now I know what you’re talking about. But the thing is I never jailbroke my phone in prior to trying the second half and I already had 5.0.1 so I thought I should skip it and proceed to jailbreaking, which apparently was a wrong move. The thing is I was fully aware of the risks involved if I were to install iPad baseband and I agreed to it.
            Later that day (I’m not sure if this was the right move), I restored my 3GS using iTunes and it worked out well. Everything works perfectly including carrier. I tried to jailbreak  and unlock again by checking “install Cydia” and “install iPad baseband” in one cycle but kept getting “iPad baseband failed”. Run as administrator, restarted PC, checked Firewall – nothing worked. Then, I repeated the process this time install each separately starting with iPad bb, still the same thing.

  • KITTU

    you are the man thanks for this affort it worked perfect you saved my time GOD BLESS YOU

    hey i have iPhone 3gs with 4.2.1 and BB 05.15.04, can i upgrade it to 5.0.1, can u please help me

  • T.Ris

    Hi Neil,
    I’ve followed all of the steps listed above to try and upgrade my previously JB/Unlocked 3GS that was flashed to baseband 6.15 (newer boot rom). When trying to restore the custom IPSW in iTunes, I always get error code 1600 or 1601 (And, yes I was using the NO_BB version). I tried the etc./hosts option with no luck. I cannot get the phone out of recovery mode (I’ve tried Tiny Umbrella, Redsn0w, etc. all with no luck). I’ve scoured over the comments in various posts attempting to fix this before contacting you but now I’m at a loss. Any suggestions or something I’m overlooking? Your time is much appreciated.

    • http://coolestguyplanettech.com Neil Gee

      seems that the iphone is not going into pwned dfu mode properly – it needs to go into pwned dfu to accept the non-standard NO_BB firmware – use the latest redsn0w ti exit recovery and to enter pwned dfu – found under ‘extras’

    • Penne

      Did you get this working?  I have the SAME problem and cannot fix anything using redsn0w as everything I try says “unexpected error”.  PLease help!!!

  • Navneet

     please help..i upgraded my iphone 3gs on baseband 6.15.00 ios 4.1 to ios 5.0.1…
    everything went fine and i succesfully unlocked my iphone by ultrasnow but after sometime my wifi did not seem to work and i tried all possible things to cure this problem but was unsuccesful….
    so i once more followed the same procedure that you have given but in itunes i wrongly selected the stock iphone baseband..so my phone got stuck on apple logo..
    so i again followed your procedure and did everything right
    but now after installing ultrasnow my phone keeps on searching for network for longtime and then says no service….i have tried your procedure 4-5 times but no results….can u plz help me or tell me how to downgrade to ios 4.1 again and then follow your procedure once again…plz help fast
    thank you

  • Benhur_1987
    • Dkkandy

      no  this is untethered jailbreak

      • Benhur_1987

        But I didn’t do it with this… I used sn0breeze instead…. Does it matter?

        • Dkkandy

          what is the version of sn0wbreeze?
          is it 2.9 then u r ok.
          if not you are on Tetheredboot.

          • Benhur_1987

            Yes it’s 2.9.1… Thx the man, I was worried cuz now I have to b with my charger next to me always…. My battery life is very poor now.

          • http://denweemlanka.com/ Dkkandy

            if you setup your phone as “New” “in phone” and do the itunes restore your prob may solve

  • Dkkandy

    Thank you soooo much.
    i did exactly what you said and i had no prob…
    but redsn0w has updated version now so there was few other things but any one could manage that.

    thank’s again.

    Also if any one got it as i am, please add a comment, not only what went wrong…
    any one gonna do this want to know who did this right, It’s the least we can do.

    CAN I JAILBREAK 3GS B/B 05.16.05 WITHOUT UPDATING B/B TO 06.15 AS I NEED GPS FOR TOMTOM APP?? IN THEORY I CAN USING EITHER REDSNOW OR SNOWBREEZE USING NO BB ON REDSNOW AND ULTRASNOW DOES NOT UPDATE B/B ANYWAY ?? CONFUSED??

    • http://denweemlanka.com/ Dkkandy

      Yes you can. jailbreak doesn’t have problem with bb, Unlocking part is. so if you not planing to unlock you have no prob.

  • Paul

    I followed this until i click the pwn dfu mode after creating a custom ios 5.0.  As soon as i click enter PWNED DFU then redsn0w crashes.  I have tried doing the administrator and service pack 2 suggestion which did nothing.  Any ideas?

    • http://denweemlanka.com/ Dkkandy

      unplug the device and replug it then run redsnow again, then it will auto recognize it in dfu

  • Paul

    I got around my last post by using ireb to pwn it, but then in itunes when i did shift restore and selected the NO_BB file it started doing everything, and it got to the apple screen on my iphone with the bar loading only a small amount before i received an error in itunes saying error 10.  I followed the instructions, got the latest software, have the old version of the 3gs, on 06.15.00 attempting to get IOS 5.0.  Any idea please?

  • Talha Ruc

    Is it possible to downgrade to ios5.0.1?

    • http://denweemlanka.com/ Dkkandy

      downgrade is possible if you have saved SHSH blobs for 5.0.1,
      have you?
      you can check it using redsnow

        How do I downgrade?

            Error 21 or Error 1600 while downgrading your iPhone,
            then the problem is that you are ending up in  Recovery Mode and not
            in a DFU mode

            screen should be black there should be nothing.

            use above instructions correctly.
            use redsn0w to get into PWNED DFU

          • http://twitter.com/Samster70 Scott Edwards

             It is definately DFU mode (Black screen) not recovery mode (Where you see the lead)

            ok, did you use Redsnow to get into pwned dfu

            because it will apply the Limera1n exploit.

             yes, redsm0w used for pwned dfu and it displays Limera1n exploit.

    I tried upgrading my jailbroke and unlocked 3GS on 4.x.x.  Followed all directions but got stuck at errors 1602 (which I fixed) and now 1601.  Problem now is it will not get out of DFU AND resn0w says “unexpected” error when I do anything.  I have rebooted and nothing.  Any help, please!!!!

    • http://denweemlanka.com/ Dkkandy

      this happens because the device wasn’t properly put in DFU mode when attempting to have iTunes restore the custom ipsw with the device. you should enter “pwned DFU”

      do it according to this article.

  • http://denweemlanka.com/ Dkkandy

    have you installed Ultrasn0w?

  • rob

    So, I followed the instructions on this page exactly, but now my iphone 3gs is stuck in dfu mode, and I can’t get it out!

Please help me, my iphone is pretty much bricked. I tried to see if i could just restore it to stock, but the iphone won’t even show up in itunes! Any help would be appreciated.

      have you tryied redsnow? try it

      if doesnt try this also

      open itunes
      disconnect phone from pc
      hold home button few seconds, without releasing it connect it to pc

  • Penne

    I was able to use tinyumbrella to get it out of DFU and functional.  Now hoever, I am not able to restore to upgrade.  iTunes get stuck at “verifying restore” – it does one of these and proceeds correctly, but then gives this status again and never proceeds.  Everthing ends with “iPhone could not be restored.  An unknown error occured (1602)”.  I can then get the phone working using tinyumbrella – redsn0w gives me “unexpected error” when using that method to get out of DFU.  Also, in checking the ios, I am now at 4.1 where I was at 4.2.3 before.  Please help!!  Thanks.

    this is what i’ve done n still getting the error 16XX

  • Guest

    I naively forgot all about the no-no on regular updating through itunes for a jailbroken phone (I just received my ipad and was eager to get all my devices to ios5, move to iCloud, and finally sync my Calendar properly — my phone seemed to be the only device had everything, mobileme would pick and choose events to upload to the server). Of course, in the process I am now sure that I’ve lost my calendar.. After installing ios5 through iTunes and getting the “you are trying to activate a phone without a sim card” error, I panicked and did a factory reset (forgive my stupidity, I am recovering from a flu and 3AM was beginning to feel really late for me).  

    This post is superb! Should someone in my situation (stuck in activation phase) go into DFU first and make sure I still have the baseband I had on the jailbreak? (06.15.00) Or should I treat it as a virgin phone and follow the Hactivate instructions?

    I don’t think I’ve bricked this thing, there always seems to be a way out.. but I am phoneless until I fix it.. I really don’t want to give into Rogers and buy a new iphone, extending my plan another 3 years… Help?

    • http://coolestguyplanettech.com Neil Gee

      your baseband should still be 06.15.00 so just follow the 2nd half of the guide

  • http://coolestguyplanettech.com Neil Gee

    You are not going into pwned dfu, you are going into recovery mode (itunes/USB logo)

      I think Apple has stopped signing 5.0.1 as 5.1 is now out – you will have to wait for a jailbreak update

      • Vig Vishal

        Sir before that i have only 3.1 ios install when i m trying to update it to 4.3.3.& 5.0. also display error 3194 ……what can i do i want my iphone in working

        • http://coolestguyplanettech.com Neil Gee

          as I said you can’t restore to 5.0.1 as the signing has stopped you have to wait for next jailbreak

  • Culmaitrik

    I do not understand why this guide is invalid now for 5.0.1 as said in the “Update”. It should still work if someone wants to upgrade from 4.1 to 5.0.1 using the guide above, isn’t it? If not, why?

    • http://coolestguyplanettech.com Neil Gee

      Apple has stopped signing 5.0.1, this guide is now for iOS 5.1

    Know can i try the above for my iphone 3gs ……..is it k

  • MrVideo2

    Hi. Thanks for this guide. Before I start, I am on an already unlocked and jailbroken via redsn0w 0.9.2 iPhone 3gs firmware 3.1.2 BB 5.11.07 but I have the 359.3.2 bootrom. My shsh are on Cydia from way back when I did all that stuff and I recall doing something with my hostname then as well (all a fuzzy memory).

    I need to go to 5.1 and am used to a tethered boot so no worries there….but I want to make sure I don’t get caught in some of the 16xx errors being reported at 8).  Are my starting conditions right for this procedure?  Anything I should do to ensure successful pwn DFU etc?

    TIA

  • MrVideo2

    Sorry about the duplicate post.  I made a post before doing the verify step after registration. Basically, I have a redsn0w 0.9.2 jailbroken and unlocked 3gs that is on FW 3.1.2 and BB 5.11.07.  I checked and I have the new bootrom 359.3.2.  It’s been a long time since I did the jailbreak/unlock but I remember doing something with hostnames to fake out iTunes or something (fuzzy).
    Anyway, are these the right initial conditions for this procedure?

    • http://coolestguyplanettech.com Neil Gee

      your conditions are looking good – any 1600 errors are custom apple entries in your host file which will need to be deleted if you run into them

  • http://coolestguyplanettech.com Neil Gee

    don’t upgrade via iTunes the regular way – do a custom restore as per guide.

    Sync with iTunes before restore so apps can be restored (any Cydia apps will need to be re-downloaded)

  • Culmaitrik

    After following the above procedure, my iphone 3gs got stucked at whte screen. If I try to repeat the above process, on step 8 of itunes, it again gets stucked at white screen and itunes gives error 28.  Please help!

    • http://coolestguyplanettech.com Neil Gee

      disable any security protection on the PC if that doesn’t fix try again with different USB cable

  • http://coolestguyplanettech.com Neil Gee

      Thanks Neil, I used a windows 7 laptop and there was no problem like i found in windows xp. But then now im stuck after the upgrade. Looks like my jailbreak is not happening. 

  • MrVideo2

    Getting error from iTunes during the restore step (of no-bb IPSW).  The error says “The iPhone “iPhone” could not be restored. This device isn’t eligible for the requested build.”

    I am on latest iTunes and 3gs FW 3.1.2 BB 5.11.07 new bootrom. Not sure what to do. ANy ideas?

    • http://coolestguyplanettech.com Neil Gee

      you need to check your hosts file as it is probably blocking apple servers

  • http://coolestguyplanettech.com Neil Gee

    you need to read the guide – clearly it states about tethered boot

  • http://coolestguyplanettech.com Neil Gee

    ultrasn0w works on preserved basebands for the following –

  • http://coolestguyplanettech.com Neil Gee

    CDMA – Here’s what i found on this – “there’s no need to create a custom firmware for CDMA iPhones, just update to stock iOS5 and then jailbreak with redsn0w”

  • http://twitter.com/Samster70 Scott Edwards

     Hi

    I am trying to perform a ios5.1 upgrage on a 3GS (BB 06.15.00)

    I am unable to follow the instructions precisely as above because i cannot install ultrasn0w at step 8, it wont let me get past activation due to sim unrecognised.

    I continue through your instructions and install the stock ispw in pwned mode fine, then install cydia – ultrasn0w at that point.

    I did a reflash and tethered boot but still no unlock.

    I know its not strictly in the order you mentioned above, but I couldnt do so as I explained above.

    Do you have any suggestions please? 

    • http://coolestguyplanettech.com Neil Gee

      I had to try a few times to install Ultrasn0w – there is an update for it coming out in the next couple of days

    • http://coolestguyplanettech.com Neil Gee

  • Christopher

    I don’t wanna ask stupid questions but my iPhone 3GS is American and I have a Curia jailbreak with 6.15 firmware, will syncing my iPhone to iTunes update the firmware? I really don’t wanna do this incorrectly and lock my phone.

  • Christopher

    I meant cydia* haha stupid auto correct.

  • http://www.facebook.com/profile.php?id=550104497 Mathews Yohannan

    Dear Niel, There seem to be a issue this time with following the procedure explained above. I used the process defined by you ealrier for iOS5.0.1 and it worked fine. Now when i saw this update for iOS5.1 thought of doing the upgrade. But then for some reason my sim card is not yet detecting, though im able to go through the process explained above with no problems. I can see the version is updated as 5.1 (9B176) and modem firmware is 06.15.00. im seeing the message near the network area as no service. :( Can you give some idea where am i going wrong?

  • http://www.facebook.com/profile.php?id=550104497 Mathews Yohannan

    Also would like to know if cydia installation has to be done without the sim card installed? i was doing the entire process with the sim card installed. 

    • http://coolestguyplanettech.com Neil Gee

      is ultrasn0w installed?

      • http://www.facebook.com/profile.php?id=550104497 Mathews Yohannan

        Yes its installed and still i see no service. 

      • http://www.facebook.com/profile.php?id=550104497 Mathews Yohannan

        I have done multiple times resintallation. ONly one thing i need to try now is should i flash the modem firmware again? do you think this can help?

  • Slimm_Pickens

    Neil..need a hand here, bud!  I’ve got a 3GS, old bootrom, already JB on 5.0.1 with 5.11.07 BB and unlocked with unltrasn0w.  It is untethered.

    When I run the latest RedSn0w it gives me an error say that the “memory is exhausted” and quits.  I saw an earlier post where you recommend rebooting and run it as the Admin.  I did that and I am the admin on this box (XP PRO-SP3).  But, it still won’t run.  I even tried it in safe mode :) but that didn’t work, either.

    Any thoughts?  Thanks for the great post!!

    • http://coolestguyplanettech.com Neil Gee

      the ‘memory exhausted’ error is an issue that the dev teams’ musclenerd is looking at – they suggest an alternative PC/Mac until it can be resolved

    • Jayguy

      Hi Slimm,

      Ran into this memory error myself and copied redsn0w from a PC running XP with 3gb RAM to a pc running windows 7 with 8gb RAM and it ran to completion creating the customized IPSW.  I did this JUST to create the IPSW, and plan to try to run the rest of it from the XP machine once I copy the new IPSW over to it.

    • Roger

      Wow! How did you do to you 3GS ? Untetgered jb & unlocked on iOS 5.01 with bb 5.11.07, seems like perfect combo, can you share how you do that?

  • JayGuy

    Hi Neil,
    Thanks for all the effort to educate folks on this process.  I’ve just got what I hope are a few quick clarifications before I proceed.
    I’ve got a 3GS, old bootrom, currently JB and unlocked from about a year ago when I was contemplating using it with another carrier.  Version 4.0 and BB 05.13.04.  I’m no longer interested in having it unlocked.  

    1.) If I just install the regular iOS 5.1 using ITunes, I understand the baseband will update to one that is not currently unlockable, but if I read the instructions and posts correctly, it won’t be “bricked”, and I’ll still be able to Jailbreak again, is that correct?
    2.) If I do the regular iOS 5.1 using ITunes, can I just do it as a regular update, or do I need to do at as a restore to avoid bricking?
    3.) If I follow the first half of the instructions, I can upgrade to a custom iOS 5.1 and the only difference is that it will preserve the unlockable baseband, correct?

    I basically just want to upgrade this to a new iOS, while making sure I don’t get bricked, which I have heard/read has happened when upgrading the iOS on unlocked phones.

    • http://coolestguyplanettech.com Neil Gee

      Stick with 3 – once jailbroken – stay jailbroken – always work with custom IPSW

    any suggestions?

       I was having the same issue (T-Mobile, 3GS, 6.15.00, re-flashed ipad BB with no luck) I finally uninstalled both ultrasn0w and the ultrasn0w fixer, rebooted, then reinstalled “ultrasn0w fixer” first then reinstalled “ultrasn0w”. Up and running again. Hope you have the same luck I did.Took a few minutes to get back on the T-mobile network BTW.

  • http://coolestguyplanettech.com Neil Gee

    you would only need ipad baseband if you want to go to that baseband ie 06.15.00
    if you already have an unlocked baseband then don’t worry about it

  • http://coolestguyplanettech.com Neil Gee

    if you have old boot rom then give the reflash a go

  • Thunnisett

    I followed the instructions and it worked, although it was tethered…… just setting it all up and then it turned off and would not come back on………  not when I go to ‘just boot’ I get a white screen….

    any ideas?

    Its a 3gs, ios 5.1, BB 06.15. Old bootrom

    now all I can get is DFU mode, or white screen. tried following instructions from beginning again but no different.

    Hi Neil, Great to see you responding to all the comments. Apologies if this has already been covered but i need help.
    I am running 4.3.3 on baseband 6.15.00 (I fell foul of GPS loss), I have new bootrom. I am unlocked. Is there any point me trying to upgrade. Is there a fix for the GPS? Thanks.

Anything else that im missing out which is causing this problem. I already would have tried following the entire process for more than 15 times. just now tried this new option you mentioned about ultrasnow fixer. hope to see some solution immediately.

    Dear Neil, i need to say a  big thank you to you. It finally worked after i uninstalled ultrasn0w and then did ultrasn0w fixer and then reinstalled ultrasn0w.My telephone service is active now. I can put any sim. But then now im seeing another funny problem. My iMessage is ON. but when i try to send an imessage to someone it say not delivered. im able to browse. all that is working fine. So hope its nothing to do with the upgrade. Any such instances in your experience yet/

    Can i update my 3GS with base band 06.15.00 running ios 4.2.1

    • http://coolestguyplanettech.com Neil Gee

      yes

  • VP

    Hi Neil Gee,

    You have explained all the steps and precautions very clearly. Thanks for your clear guideline. But before starting i want to clarify my doubts.
    I have unlocked, jailbroken iPhone 3gs with 
      iOS –> 4.0(8A293), 
      Baseband(Modem Firmware) – 05.13.04, 
      Boot Room –> new boot room (4th & 5th digits in serial number is 47 which is above 40)
    I Want to update my iPhone firmware to iOS 5.1 or iOS 5.0.1
    I have few questions before proceeding the steps to update firmware to iOS 5.1 followed by jailbreak and unlock.

    Query 1) The steps you have shown will work same way in Windows OS too ?

    Query 2) Do I need to update to iOS 5.1 firmware without updating the baseband? Or can i directly update iOS from iTunes without taking any such baseband precaution?

    Query 3) If i jailbreak the updated firmware 5.1, It will be tethered or untethered jailbreaking ?

    Query 4) If i update it to iOS 5.1, will i loss all the applications dowloaded with installous? How can i take backup of those application and get it back once my phone is updated?

    Thanks

    • http://coolestguyplanettech.com Neil Gee

      1- yes
      2 – if you update via iTunes you will lose your unlock – update to custom IPSW as in the guide
      3 – tethered
      4 – i don’t know about ‘installous’

  • Gtm28

    I just completed and follow the entire process jailbreaking and unlocking my 3GS iPhone… Jailbreak went fine, however no luck with the unlocking parte.  The only thing that I dont have (after reading some posts) is the AT&T Sim Card. Nothing was mentioned about this on the procedure… Does it affect my ability to unlock the phone? I am getting the No Service icon after entering my T-Mobile Sim Card. What is the Re-flashing that you mentioned?

    • http://coolestguyplanettech.com Neil Gee

      have u installed ultran0w

      • Gtm28

        yes… and complete re-flash. Forgot to mention before….Version 5.1.. bb 6.15.00. Still same No Service error… 

        • http://coolestguyplanettech.com Neil Gee

          delete ultrasn0w – install ultrasn0w fixer then ultrasn0w

    hey buddy waiting for a reply ! 

    • http://coolestguyplanettech.com Neil Gee

      1 – tethered if new boot rom / untethered if old boot rom

      2 – activated after cydia/ultrasn0w installation
      3 – yes – if u have an issue installing ultrasn0w install ultrans0w fixer first

  • Mikey

    Hi Neil,

    I have a 3gs with firmware 3.1.3 and baseband 05.12.01, but with the new bootrom.  when i started the process, and chose custom IPSW it asked me if it was old or new boot rom, with a note that says if its a new bootrom i need the SHSH blobs to finish the restore.  is this true?  

    thanks so much for this!

    • http://coolestguyplanettech.com Neil Gee

    Hello Neil,
    thanks alot for the step by step guide and it really helped me to Update and jailbreak and unlock my 3GS 32gb….
    all went fine, but i had problem with utrasnow and as you advise i have installed utrasnow fix and now its working well….
    actually everythings went well but now i am with a strange issue…!!
    1) sound is not always available… not from earpiece, not from loud speaker or handsfree… and when it works it works from all…. pls advise is it a software issue or hardware issue..?
    2) sometimes when i push sleep button or home button, then nothings happend……though if i call on my number from other phone i can hear the calling bell on other phone but my 3gs have no reaction…. also at this stage if i connect to pc then it also doesnt show connected on itune…. but after sometimes it automatically behave like normal… pls advise is this a “SOFTWARE ISSUE” as all is well when it works except sound issue….

    thanks in advance

    Hi Neil,
    How are you?  I have iPhone 3gs, ios 5.0.1, BB 05.16.05. Never jail broken. I think it was with carrier O2(UK) and unlocked by them, so now it’s unlocked (I can use any sim).
    Can I update to ios 5.1 and jailbreak? Will I loose my unlock?
    Thanks

    • http://coolestguyplanettech.com Neil Gee

      If you have verified that it does work with any SIM card then great you have an unlocked iOS5.1 baseband – yes you can jailbreak and your unlock will still be valid

    • ljh

       Hi Zef

      My phone is the same as yours? (newer 3gs on bb 05.16.05 / 5.0.1 and I too have had the phone unlocked by my provider) I am now wanting to JB and am unsure of the best way / if there was anything special to do???  Just wondered if you had done it yet!!??  Any tips / advice would be greatly appreciated.

      Thank you

    Hi Neil Gee
    I have jailbroken iphone 3gs which i by mistake upgraded to ios 5.1 thorugh I tunes (apple) and my phone got locked.
    I reflashed to ipad baseband and then again followed the all above steps.
    and lastly i installed utrasnow fixer and ultrsnow 1.2.5 to unlock the phone, but even installing both the app, my phone is not able to capture network.

    Please note that the baseband says 06.15.00 after all re flash and jailbreak process followed.
    Please Help.
    Thanks in Advnace

    I can’t believe (well I can) that you upgraded via Itunes to iOS 5.1 – after the effort I put into help you last time, I think maybe you should get a different phone

    some people need SAM as iMessage doesn’t work – so then they install it – but is no problem right?
    this process has worked for me but doesn’t work for all – its unpredictable – so install SAM if u need to

  • http://coolestguyplanettech.com Neil Gee

    don’t update via iTunes – you have to follow this guide

  • http://coolestguyplanettech.com Neil Gee

    if you follow the guide the baseband will not change

  • Fritz3213

    I have an iphone4 currently operating on cydia (i presume that it is jailbroke) but the Sim is still locked to Vodaphone UK.  The baseband is 04.11.08 and dont see this listed in the current unlock section.  Can this be unlocked to any carrier through Ulrasn0w?  additional info below.

    version: 5.0.1 (9A405)
    CARRIER vodaphone UK 11.0SERIAL LAST NUMBER 4th & %th digit – 40MODEM FIRMWARE 04.11.08

    I would like to upgrade to iOS 5.1. and use the phone on any network as well.
    Would you be so kind as to direct me in the right direction with regards to achieving my aim.  Thank You in advance.

    Regards

    • http://coolestguyplanettech.com Neil Gee

      this will only work with Vodafone until the baseband is hacked to become unlockable

  • http://coolestguyplanettech.com Neil Gee

    try ultrasn0w fixer

  • http://coolestguyplanettech.com Neil Gee

    delete ultrasn0w install ultrasn0w fixer then ultrasnow

  • http://coolestguyplanettech.com Neil Gee

    well your baseband will be updated so then it cannot be preserved so if you dont care about that then it is OK, and you could just jailbreak

    jailbroken = yes, unlocked= no

    Hi. Just as I thought I had it all done and everything was working, the same thing happened to me. Now when I try to just boot tethered using redsnow, the screen turns white and stays there even though redsnow tells me that the reboot is done.

    Have you found a solution to this?

    you shouldn’t update a jailbroken iphone via iTunes – this link should cheer you up…

      Liverpool Loosing badly to QPR, Wigan , that is not the thing to enjoy for me, its saddest part.

  • http://coolestguyplanettech.com Neil Gee

    unfortunately that is not possible – the only thing you can do is use the original carrier or wait for an unlock for that baseband

  • http://coolestguyplanettech.com Neil Gee

    you can update from a custom IPSW but since you already upgraded via iTunes this means your baseband is unlockable – so if you just want to jailbreak follow the 2nd half of the guide

  • Owen

    I have old style 3GS. I applied BB 06.00.15 and upgraded to 5.0.1. I installed ultrasnow and it picks up reception. However even though it shows full reception it is unable to make calls and it continually drops out.

    I decided to try and upgrade to 5.1 to fix this. Same thing happened, I installed ultrasnow and it shows full reception, but it isn’t able to make outgoing calls and messages only arrive in groups of about 10 because there is such a delay in me getting reception (even though it is always showing full bars). 

    I then uninstalled ultrasnow, installed ultrasnow 5.1 fix, and then reinstalled ultrasnow. I still have the same problem.

    Any help would be greatly appreciated.

      • Owen

        Thank you for your quick response. 

        I don’t think I can do a reflash because my serial number starts QR139. Is that correct?

        • http://coolestguyplanettech.com Neil Gee

          Look for the Serial Number – if the 4th & 5th digits are below 40 you are lucky and have the old boot-rom.

        Hey Neil..Thanks a lot dude…reflash worked and now there is no signal problem.. :) :)

    Anybody got any news on the white screen issue whilst rebooting in Redsnow. After comp0leting the jailbreak and unlock and everything working fine (except for GPS of course) my phone turned off on its own and now I cannot reboot it again in Redsnow using just boot tethered. Redsnow tells me that the reboot is done, but the phone remains frozen on a white screen. After about 10 minutes the screen goes blank and the phone goes back into DFU mode.

    I have a iphone 3gs with BB 06.15.00 old bootrom.

    Help please… Thanks

    yes you could – just beware if 3GS is new boot rom you may lose GPS

  • http://coolestguyplanettech.com Neil Gee

    whats the baseband

  • http://coolestguyplanettech.com Neil Gee

    didn’t happen to me no, it does affect a few people the best I have heard is to let the iphone drain completely out of battery and then try

    • Steve

      Thanks. If the phone is in DFU mode, how long till it drains approximetely?

    • Steve

      Did that. still didnt work. I cant explain how strange this is. It was working for a few hours after the upgrade. Used the Ultrasnow fixer and got signal too. Then it just went off and cannot come back on. How can we explain this?

    • Steve

      Well for whoever’s wondering I found the problem. Firstly, if this happens to you and you are unable to boot the phone and it is frozen on a white screen, then you can solve this issue by opening up your iphone and detaching the motherboard from the battery for a couple of hours. However, if you restore IOS 5.1 again or if you reboot your iphone, after a few hours, it’ll shut down on its own again and you’ll be back at square one. So what did I do to fix this?

      Well, apparently there is a small percentage of 3g’s that may seem to be an old boot rom, but are in actual fact new boot rom. My 4th and 5th digit of serial code are 004 suggesting that it is the old boot rom. However, after creating a custom IPSW for a new boot rom, and restoring 5.1 again using this new IPSW, I havent encountered this problem anymore.

  • http://twitter.com/Samster70 Scott Edwards

      Next Challenge,The above process works fine on my 3GS, its a tethered boot though, which I dont like.I decided to pay for a network unlock, I thought I could just re-install IOS5.1 and away to go, but it cant find a SIM card.

    Should that happen?

  • Lucky Sagoo

    hi bro.step 8) not working in my itunes….am click on restore but error(the software required for this iphone is not installed correctly. please reinstall itunes to install the required software…)………..so how solve this plz. help….  : (

  • http://coolestguyplanettech.com Neil Gee

    i think you need a reflash – Look for the Serial Number – if the 4th & 5th digits are below 40 you are lucky and have the old boot-rom.

  • http://coolestguyplanettech.com Neil Gee

    hmmm, I’m not 100% on this – but the unique identifier is the IMEI number and if your previous carrier unlocked it then that should be honoured by Apple Servers when you connect via iTunes and you may be prompted to install a carrier upgrade from the new SIM installed.

    Thats the theory – it should work – but I personally haven’t tried – so if it all goes to poo don’t blame me!

    I have an iphone 3GS on iOS 5.1 baseband 06.15 and I did all the jailbreak and when I installed ultrasnow fix 5.1 and ultrasnow 1.2.5, it still does not work with my sim card.  I did make a mistake by updating on iOS 5.1 via itunes but I checked the baseband and it is still on 06.15. I restored it again by using the custom ipsw, but it still did not work.  I don’t understand why the unlock still won’t work when it is still on baseband 06.15 and it is an old bootrom.  Help please!

  • Josh

    Brilliant, thank you. I did the old bootrom and had to do the ultrasn0w fixer in the yellow box. After a bit of panicking and restarts its finally getting signal again. Many thanks.

    Because I had to use the information in the yellow box, does that mean my iPhones 3GS now requires a thethered boot each-time?  My baseband is 06.15.00 and my serial number starts 88924many thanks Josh

    • Sid K

       Kimo,

      As the signature of your firmware (SHSH file) is not already registered in Cydia using TinyUmbrella when 5.0.1 was the latest update from Apple, you are facing this error as I did…. I guess the solution would be to move to 5.1.

    You are the coolest guy on the planet! Followed your directions and now have an unlocked, jailbroken 3gs running 5.1! Love it!
    And next, an untethered fix? I’ll be keeping an eye out for your update.

    I went through all the instructions for my jailbroke 3Gs 4.0.1.  I have the old boot rom, etc.  When Apple verified my restore to 5.1 it brought back an error message saying I was ineligible for the upgrade.  Any thoughts on why that is so?
