So let me start off saying I RESTORED from 4.0 to 4.1 in order to get the faster 4.1 update. I tried to jailbreak with redsn0w 0.9.6 b1 and it got stuck on waiting for reboot. I rebooted manually and it would NOT boot. I restored my iPod in recovery mode and it would not kick out of activation mode. I rebooted and here is what happens: My screen is totally black, it does NOT reboot, and cannot go into DFU mode. What do I do? MC 2G Model 8GB By the way! EDIT: FIXED! It turns out that even though the iPod was unusable, something went wrong with the USB drivers on my computer so I plugged it into my Mac and restored. All is good.
