I had 3.0 jailbroken software, then just today I updated my iPod to 3.1.3 software so I could jailbreak it to get 3.1.3. I'm using the iPod2,1_3.1.2_7D11_Restore with redsn0w and I get to the part where it says waiting for reboot and screen is completely black. Its been like this for about 30 minutes, what should I do?
