My iPod 2g is stuck in DFU (not recovery mode). I have a black screen on my iPod. With iReb, I can get into recovery mode but it has a screen that states the following: I attempted to restore the 3.0 ip2g firmware, but it did not work. I have tried to install the following firmwares to no avail: 2.21, 3.0, 3.1.3, 4.0. Nothing has worked. I have attempted to use iRecovery, Decovery, iReb, Ziphone, QuickPwn, etc. Nothing has worked. I have also attempted to restore the firmware using three different computers Every time I attempt to restore I get "unknown error", but with different error codes.
