Thread: iPhone 4s - is it possible to downgrade from the currently installed 5.0 to 4.2.8?

is a discussion within the

Jailbreaking the Verizon / Sprint / CDMA iPhone

forums, a part of the

iPhone on Verizon / Sprint / CDMA

section;
Just wondering if it's worth a shot - I have 4.2.8 blobs saved. Can you downgrade the baseband on the new phone from iOS5 and jailbreak the 4.2.28? Thanks, Josh

    like zoolman said their is no lower OS for the 4S.

    on another note SHSH blobs are device specific and will not work for another device.

    Additional note: basebands can't be downgraded. If youre referring to firmware version then...like the others said it can't downgrade to a firmware that it was never on before.

    The issue is there are no more SHSHs for iOS 5+. Anything below saved should be fine.

    Regarding the 4S, bc it was loaded with iOS 5 and it comes that way, it can never restore to a fw version lower. It basically can't downgrade to a fw version it had never been on before.
