yesterday evening while watching a movie it stopped and showed several commands in the background and a message to wait. After 5 minutes the device shut down and it tried several reboots but always turned from blue to red. After some more minutes the lights stayed red and even when you disconnect the power cable and reconnect it it does not start up again.
I have read that it might be a problem with the power adapter but i have not found another 5V/2A and was not able to test it.
Any other idea what could be the problem?
