I just got a 3GS from my brother and it only shows the "plug into iTunes" screen. When I plug it into iTunes, it detects that it is in Recovery and wants to restore and update. So I accept and it downloads the software and gets to just before the right side of the Apple logo and then i received an error code of -1. Apple recommends trying again 2 more times, and of course... no luck. Any suggestions? He stated it was on iOS6 but not jailbroken.
