Hi. I have a 3GS with 3.1.2 OS jailbroken and simlocked by blackra1n and blacksnow. It wasnt tethered I guess, because I could normally shut down and restart my iphone w/o needing to jailbreak it every time. I havent restored my iphone ever before. So it uses the old bootrom. 2 days ago, my iphone stuck at apple logo screen and restarting itself continuously. After many attempts with many solutions, and being unsuccessful at all, I decided to restore it with a custom firmware. I downloaded 3.1.3 firmware to my pc and with sn0wbreez, I created the custom firmware. Now, I m trying to restore my iphone through itunes with the custom firmware. BUT I m getting errors which disables me to restore the iphone. I get itunes error (2) when my iphone is in recovery state and I get itunes error (1600) when it is in DFU state. Please help me, I need my iPhone so much these days. As part of my job, I need to look at my mails while I am away too, but w/o my iphone, it really is impossible for me. This really is urgent! Please help me. My twitter account is twitter.com/pashalatzo Thanks alot.
