So I received this message when trying to restore my friend's 2g iTouch... I read the other post regarding this error message, and how you are supposed to put the ipod into DFU mode so you can then restore it, but I did this a couple of times, and I got a different error message, with the number this time being 1601. I downloaded the iPod iTouch 2g 2.2.1 Firmware from a reliable site, so I am thinking maybe it is because it is an older firmware, and no longer works? I was able to download it, and it came directly from Apple, so maybe not. Any help or advice would be appreciated, thanks.
