I ran into some serious issues that required me to use multiple Macs in order to get anywhere with this. My primary mac, a MacBook Pro OS X.5 running iTunes 7.6, wouldnt let me downgrade to 1.1.1. Could not restore. An unknown error has occurred (1604). I thought this was due to iT7.6. Delete iTunes and preferences and install iT7.5. Same results. I try restoring to 1.1.3 same error. WTF. I go to a Mac Mini running iTunes 7.6 and restore to 1.1.3 fine. I Plug the iPod back into the MBP, it doesnt detect it. I upgrade to iTunes 7.6, now it sees it but it cant downgrade. Same 1604 error. Since I dont want to mess with the mini that can restore the Touch to a usable state, I use yet another machine to restore the iPod. An iLamp running Tiger and iTunes 7.5. The first try it gives me unknown error (1). Reboot it fixes it. I successfully get 1.1.1 installed and jailbroke. I get iTunes 7.5 running on the MBP and it STILL doesnt detect the iPod!? So Im pretty convinced now that I wasnt doing anything wrong but that my MBP is the one with the issue. Any thoughts? P.S. I'm rebooting after I post this.
