i bought an iphone off ebay person stated he believed it was jailbroken but thinks he unjailbroke it i have had it for a while with no issues and all of a sudden did an update and im running into problems: my iphone 4s now is stuck on plug into itunes screen. i tried restoring and it gives me error 1603 and 1604 (not together they just alternate) is there anything i can do. is there any other programs to download that FORCE restore it. i have tried downloading the firmware and shift clicking to restore but no luck there. i have also tried to use iReb to pwn DFU mode it- thats when i started getting error 1604 instead of 1603 please help!
