Redsn0w Will Soon Support Downgrading Your Firmware for iPhone 4S, iPad 2, and iPad 3

Share:

In a recent Tweet, Musclenerd, of The iPhone Dev Team, announced that an upcoming version of Redsn0w will allow iOS users to downgrade their firmware, with saved SHSH blobs. This includes iPad 2, The New iPad, and iPhone 4S.

This is pretty big news for jailbreakers. Previously, there was no way to downgrade to an earlier iOS 5. If you have SHSH blobs saved for a firmware earlier than iOS 5, you were in luck, but for newer devices that don’t support older firmwares, this was not possible. Musclenerd says this will work with A4 and A5 devices, so does this mean they have a working jailbreak ready to go for these newer devices?

Another big thing to note is that this was only previously possible using Pwnage Tool to create a custom firware, then restore in iTunes. Now, with this new Redsn0w that “stitches on the fly”, this process will be greatly streamlined. Could this mean that Pwnage Tool and Redsn0w will be merging into one super jailbreak tool? We’ll see.

There has been no release date for the new Redsn0w, but we’ll be watching this closely, and let you know this develops.

  • I think I know the answer but I’ll ask anyways… I had my ipad2 jailbroken on 5.0.1… uninstalling a cydia tweak almost bricked my ipad2, and forced me to restore it with official 5.1…

    before this happened… i saw that cydia had my 5.0.1 shsh blob.. but stupid me i never used tinyumbrella to back it up  on to my computer…. i’m assuming there is no way for me to retrieve it from cydia.. hence not possible for me to use this future redsnow update to downgrade to 5.0.1 … correct?

    Yes you can, in the settings of TU, check the box that’s requests the blobs from Cydia to save them to your PC

    What will I data will I lose after downgrading back to 5.0.1 from 5.1? I don’t have any old backups from 5.0.1 saved in iTunes. Don’t think iTunes will let you install a recent (5.1) backups on older iOS versions…?

  • Will you be able to unlock iPhone 4S?

    why are they wasting time with going backwards. all this effort. Release the jailbreak for for the new ipad already. all the votes were counted and a the masses spoke!  

  • Accordtr

    And how in the world would you have your blobs saved on the new iPad? It would have to be jailbroken to get them???

  • Thanks Helper I got my SHSH blob!!  Kudos!!

  • whatever it said about the new ipad is BS. caz there is no jailbreak for it
