I wanted to get rid of all of my jailbreak data, and I didn't restore the iPod with iTunes because that didn't delete all the files. I went to Settings, General, and reset all data and content. I wanted to totally wipe it. It said it would take about 4 hours and I am going on 8. The loading bar finished, and now there is just an apple logo in the middle of the screen, like when you are booting up, but with a loading circle in it sometimes. It seems to go on a cycle. After a while, the screen flashes, and the screen goes back to just to the apple logo. Then, a loading circle thing appears on the Apple logo. Repeat. For 8 hours! I tried connecting to iTunes but it didn't recognize it, and my computer didn't recognize it either. I am now trying to drain the battery so it will stop but I still need help. I am on 3.1.3 but jailbroken and am trying to unjailbreak via onscreen reset, not iTunes restore.
