Ok, Today i decided just to restore my jailbroken ipod touch and update the firmware. so i decided to restore it from the actual device settings which it said would take about 2 hours, which it did, then it began rebooting upon doing this the apple logo would sit there for 5-10 minutes then it would go to a black screen and repeat. it has been doing this for the last 5 hours and i dont know what to do. PLEASE HELP!!!!
