Hey guys, i tried rebooting my jailbroken ipod touch 4th gen (4.2.1) on redsnow (because it is tethered), it usually works, but this time it told me there was an unexpected error and it stayed stuck on the apple logo. I tried rebooting it again , again there was the unexpected error. When i tried restoring it on itunes , it told me it was already in DFU mode and i tried restoring it. It extracet the software but when it got to the point where it prepares ipod for restore, it stays stuck on it for 5-10 mins and then tells me that there was an error. (sometimes no. 1604, another 1601). Another thing i noticed is that, it stays stuck on the apple logo and every 5 minutes the screen turns white, then black, then the apple logo comes back up again and this every 5 minutes. I tried rebooting my brothers ipod touch 4gen which is also jailbroken on iOS 4.2.1 and the same thing happened. Now im stuck with two ipods stuck in DFu mode and i dont know what to do. Please help. Thanks already. Owner of Ipod Touch 4th gen , MacBook 2007 2.16 Ghz 120 GB .
