I was restoring my iPod touch 2g to iOS4.0, and the progress bar stopped right before it completed, I'd say about 97%. I looked it up and someone said try reinstalling iTunes. That didn't fix it. I then tried it on my laptop just in case it was the computer. I got error 13. I then tried to put it into DFU mode, and this was a problem. It seems to be stuck in Recovery mode. As soon as I plug my iPod into the computer, it turns on and instantly goes into recovery mode, even if I turn it off while plugged in it just turns back on. There is no opportunity to do the DFU button combo.
