I was restoring my friend's iPod and it said "connect to an external power source to complete the process." The only problem is, I don't have an external power source! I have an iHome, but nothing shows up when I dock it there, and I can't use the USB port, because it will give me the Apple logo then "connect to power" logo. It's not recognized in iTunes so I can't restore it. I can't force it in to disk mode either. What should I do?
