So I'm on 4.2.1 and my iPod decided not to let me sync music. By that I mean that after a couple of seconds of transferring music, SpringBoard will reset itself and I'll have to restart my computer in order for iTunes not to freeze when I plug in my iPod. It was jailbreaked using GreenPois0n RC6. I figured, "I'll just restore to 4.2.1 and rejailbreak, not a big deal". All I had was apps anyway, nothing really. So I enter the iPod into DFU Mode and Shift-Clicked "Restore" to bring up the 4.2.1 IPSW. Click restore and iTunes does its thing. The Hosts file is modified to reroute gs.apple.com to 184.108.40.206. I have saved my 4.2.1 SHSH blobs using TinyUmbrella. It gets to the "Restoring iPod Software" stage and will freeze about 10 seconds in and so far hasn't budged for about 5 minutes. My iPod has a screen like this except nothing has passed through the progress bar: My computer has iTunes at this step: Any ideas? I've tried using a different cable and no dice. I'm on iTunes 10.2.1 (latest) if that makes a difference. All I can do is wait or hold the power button to get out of it and iTunes will shoot me a 14 Error.
