I have a iphone4 on 4.1. I was jailbroken but I am not right now. I tried to restore and update and my phone will not update to 4.2. Every time I try my phone goes into recovery mode. I was able to restore using the 4.1 ispw file. I even tried using the 4.2 ispw file but that didn't work. Does anyone out their have any ideas why my phone won't update? Thanks for looking.
