This process upgrades your iOS jailbroken device to iOS 6.1.2
If you need your baseband preserved because you are on locked iphones and need the baseband to unlock with ultrasn0w then stay away from this and wait until the next version of redsn0w.
For this jailbreak you will need to upgrade your jailbroken iPhone to iOS6.1.2 via iTunes the regular way and then re-jailbreak your iOS device using evasi0n version 1.4.
This will only work on iphones, ipads and ipod touch that are already on iOS 6 – iOS 6.1.2
This will work on:
- iPhone 3GS
- iPhone 4
- iPhone 4S
- iPhone 5
- iPod Touch 4th Gen
- iPod Touch 5th Gen
- iPad 2 & 3
Pre-Upgrade Tasks – Back Up
– Connect device via USB to computer
– Back up device in iTunes
– Disable lock passcode on iOS device
Upgrade to iOS 6.1.2 by Restore iPhone…
Connect your iOS device to iTunes and upgrade to the lastest version via a restore.
Restore if Upgrade Fails
If you tried the upgrade button and the process fails – you will be offered a restore – which will restore the iphone to factory settings but at the latest iOS – this will more than likely happen on a previously jailbroken iPhone. Click on restore and update. Then you will be prompted to restore the last data back up.
If you are a OSX user on 10.8 control click/right click open to get around the Gatekeeper security issue.
If your iOS level is too low – you will be told.
Otherwise – click on the jailbreak button:
Let evasion carry on with the process on your device
During the process you will be prompted by evasi0n to interact with the iPhone
Find the Jailbreak app and click it
This will complete the jailbreak process.
Now messages will appear on the iPhone that relate to Cydia and setting up Cydia – let this run and clean up and reboot.
Cydia version 1.1.8 will now appear as an app on the iPhone springboard, launch it and let it prepare the file system – this can take a while. After it finishes launch Cydia and upgrade any packages including an evasi0n upgrade that allows an untethered boot – then reboot the device when prompted.
