While playing a game app today, I had my iPod charging at the same time. A few hours later I noticed that the battery was still pretty low. The following error appeared on my PC screen. Exact message. Power Surge on Hub Port. A USB device has exceeded the power limits of its hub. I can't take it back to Apple, it's jailbroken and impossible to restore since iTunes won't recognize it. I've tried all my USB ports. Any suggestions? Any other way to restore firmware?
