Thread: Setup for 3GS downgrading, but what about 3G?

  1. #1
    Default Setup for 3GS downgrading, but what about 3G?
    I followed instructions for storing ECID on Saurik's server (cydia shows it is stored). My wife however has a 3G. What do I need to do to be able to downgrade FW (we both are on 3.1.2) on her phone, if the need ever arises?

    I heard iH8snow is releasing iREB 3.1.2 tomorrow, but am not sure what it does / is used for.

    Any ideas?

    3G doesn't require any special files, only 3GS.

    Yea 3g is easy to downgrade . . . You can just use shift-restore the earlier firmware and then use quickpwn to sort it out then jb from there...

    there's a good guide somewhere on this
    Don't worry I'm not in jail anymore
