I had the same issue after upgrading the OS to 4.5.xxx. Worked fine while I was using it, but when I set it aside and the screen went dark it would go into a continual reboot cycle. I removed the 2G media card and the problem stopped. I wiped all the files on the card and reinserted it and it still works just fine. Hope that works for you.
