I charged my R8a and it goes on but wont stay on. It is like "looping" all the time and I can't turn it off.

This may not be the answer you are looking for but your I pod might not be fully charged, meaning that you are not plugging it in the computer/docking system long enough.( it takes much longer than 15 minutes to charge the battery. So you might want to plug it in/dock it over night) Or you may be playing a game that uses a lot of MB/GB so it kills the battery. And make sure that you press the play/pause button down for at least five seconds before switching the little switch at the top of your I pod. If you don't press the play/pause button for five seconds and just switch the switch at the top a little lock will appear on the left corner meaning you need to hold the play/pause button down for five seconds then the i pod screen goes black at that time flick the switch at the top off. -hope it helps owner of i pod nano and I pod touch.
