Yes. I then get a yellow frame around the USB button and when I relase the pen, the frame turns blue. But is keeps displaying "Host". I also tried writing "otg" into that /sys/... file, but when I "cat" that file I don't see any difference.

Meanwhile I have a new Battery, but it does not make any difference. Can hardly use the alarm anymore, becuase the "low battery" signal wakes me up before the alarm goes off.

Ideally I would now reflash and see if the problem persists. But I don't know how to restore everything once the culprit is found. I boot from internal mmc. Would that survive the reflashing? So I only had to reinstall bootmenu?

If that fails, I have a hardware issue. If I buy another n810 I would like to restore everything there. I assume I could just tar my internal mmc partition and untar it on the target device and reinstall bootmenu?

Or how would you do such a transplantation?
