    Question [IPSF] How to undo ?

    Hey,

    a little bit ago I did the Geohot IPSF Style unlock on my 3.9 iPhone.
    The Problem is I forgot to safe my seczone, I know it is the worst thing that could happen.
    Since I had some trouble with this hack and I'm thinking to give my iPhone to a Friend I was asking myself if there is a solution to undo the changes made by this hack. I searched a bit, but all the solution are assuming I have the seczone.
    Why isn't it possible to just rewrite the whole bootloader? I mean there a solutions available to rewrite the bootloader from 4.6 to 3.9..


    Thanks

    Yes, there is, either via herdware (not recomended), or via software, use ZiPhone and "click to show advanced fuctions", then uncheck everything except downgrade bootloader, but thing is that IPSF use seczone to unlock, and you my wery well endup with a brick (that is why you should make 4-5 backups on varionus places,computers,medias ...), sorry ..... did you sad you have 3.9 ?

    Yeah I'm on 3.9, taht why I'm not sure if I can use ZiPhone BL Downgrade, because it's written for 4.6...Is there no way to "restore" the seczone? I heard it's a unique one for every iPhone, because it depends on the NOR chip.
    Is there no way to "calculate" a new one?
