can anyone give specific instructions on how to downgrade from 1.0.2 to 1.0 with screenshots?

A patched version of bbupdater that allows a downgrade (instead of saying "a later version is already installed, can't rollback") has not been released.

It's not hard to do, though. IDA is your friend.

But now the real question is, is it enough to patch this in bbupdater or would you need to play with the firmware SecPack or other similar stuff as well ?

hi, i also want to restore my iphone to the first version, because i m having trouble unlocking it, since i updated to 7.4.....

thanks
