hi, i am trying to restore my iphone 3gs and at the end i get a error -1 and i cant exit recovery mode. i used ireb and tinyumbrella. i tried restoring the iphone on 2 computers, my macbook pro and hp g71. so far nothing worked. i also tried putting it in dfu mode and restoring. still no solution. i checked what that error meant, it said something about a last ditch method or something like that. i tried using custom ipsws from snowbreeze and it still doesnt work. please help this is my friends phone and i dont want to mess it up for him please
