Preserve iOS 6 baseband – Create iOS 6 Custom IPSW Firmware

iPhone 4 & iPhone 3GS ultrasn0w unlockers will need to preserve the older baseband in order to unlock. Click on the Extras and then on Custom IPSW option, select the required iOS 6 IPSW and let RedSn0w make the custom firmware. After that, enter Pwned DFU mode by selecting “Pwned DFU” from Redsn0w’s Extras option, and then restore to this custom firmware.

Booting Device tethered on iOS 6:

You will need to boot your device in a tethered mode every time the device is turned off. It’s simple, go to RedSn0w and click on extras, and click on Just Boot option. Follow the instructions and you will be rebooted back into the tethered jailbreak mode.

The new re-store features allow third gen iPad and iPhone 4S users to re-store to any version of iOS 5.x although Apple is not signing the software. You will just need the SHSH blobs for your iOS 5.x. The downgrade can only be done if you updated your device using iTunes and will not work if the upgrade has been done OTA (Over The Air). iPad 2 users will be able to downgrade if they have blobs from 4.x and 5.x saved. The A4 based iPhone 4, 3GS and 4th-gen iPod touch users can downgrade to an older firmware for untethered jailbreak provided that they have SHSH blobs saved for the firmware they want to downgrade to.

There are still no iOS 6 untethered jailbreak although the Dev teams are working hard on the issue. Stayed tuned for more unlock & jailbreak updates and feel free to comment. As soon as any new update concerning jailbreaks come out, we will let you know ASAP.

    What if your phone factory unlock do you still have to preserve your baseband?

  • valbonab

    I tried to jailbraik on Iphone 4 but during the process it freezes and redsnow shows erorr and stops. It seems the iOS 6 is harder to crack. Also, during the process of jailbraiking the process loads lot of memory!! Did anyone tried it yet?

  • UnlockBoot

    No, Factory Unlocked iPhones can be updated without preserving your baseband.
