So the other day I received a Touch iPod 4G. I used redsn0w to unlock it (tethered unlock) on the 5.0.1 firmware. Everything was fine, jailbreak worked and all. I decided that I didn't want to deal with a tethered unlock so I went to restore it to factory, There is no important information on it, so I was content clean wiping it. When I boot it normally, it gets stuck on the apple logo and wont boot. iTunes also won't recognize that it is plugged in. I put it in restore mode and DFU mode (at different times) and iTunes then recognized it, but not as my iPod's name, but just as "iPod". I kept getting errors varying between 1600-1604 when trying to restore it via iTunes. So I boot tethered it and it turns on and works normally. I then plugged it into iTunes while it was on boot tether and tried to restore it then. It recognized the iPod as mine. I then went to restore it and I got error 21. error 21 is something with your antivirus, so I uninstalled my Norton Antivirus yet I still got the same 21 error. I then used the "Erase All Content And Settings" option out of a last resort, so to speak. It has been giving me that spinning white wheel for about 15 hours now. Did I do something wrong, or did I miss an obvious step in restoration? Any and all help is appreciated. Thanks.
