I don't see the steps that Brad had you do so if you could maybe relist those, that would be great. I am having a similar problem. My phone is stuck off and only goes to the screen with the itunes logo on it when I plug it in. I keep trying to restore it and follow instructions I'm finding online, but have had no luck so far. My phone had already been unlocked and jailbroken using Redsn0w. I keep getting different error codes. From 1611 to 3194 and now 1600. I am getting so frustrated!! Any help or advise would be truly appreciated!
Answer to: Bricked, cant restore or fix
