Hello. My mother bought a used iPod mini from a yard sale for $5. Supposedly it was sold because the owner just bought a touch. She said there was nothing wrong with it (of course). Anyways, my mom told her she already has a cable for it. My mom only has usb iPhone cable with wall plug. She plugged it into the wall for about an hour, then I plugged it into her Mac and did an erase and sync. After that I got an update message and like an idiot, hit okay. When it was finished the update (or so I thought) it said it had to be plugged into a wall adaptor, and displayed a graphic which looks like a laptop charger. I plugged it into the wall, and an hour later it still shows the adaptor graphic. I tried to reboot it and it goes from the Apple logo back to the adaptor. Any ideas on what I can do??
