I have an 8gb 2nd gen ipod touch that I just purchased used (ebay). When I press the power button the apple logo is visible for a 1/2 second, then the screen flashes white and then goes black. When the ipod is connected to the computer it goes to restore mode. So I tried to restore with shift restore using 3.1.1, 3.1.2, 4.0 etc with no success, I get error 1610, or 3194 if I tried older OS. I also tried restore and update with the same results. When I try DFU mode (yes I know how to put it into DFU mode) restore it will get to the apple logo with an empty status bar and iTunes says "waiting for ipod" forever. I have also tried 1clickboot, iReb, ih8sn0w, and have not gotten any further. ih8sn0w did get the ipod to show a screen that said it was ready for os 3.0 and to connect to iTunes, which I did, and tried Shift restore w/3.0 then iTunes could not install the os successfully. This ipod touch is not under warranty, shows no sign of liquid damage, and I will not be taking it to the Apple Store. I read on here that it is ALMOST impossible to brick an ipod, well I hope someone has a way to get this paperweight functional again! Thanks for your help!
