Was playing around in developers options and I think I selected boot from ???? Next time and forgot to switch back. Now it just loads splash screen then turns off and loads splash again. This just keeps going like that. Is there a way to start unit in service mode?

If we did anything wrong, couldnt we take unit out, disconnect from power for like 5 min?  Everytime mine lost power in process of install, all my settings were erased.  Assuming the same would fix this issue?

what did you change??? try testkey_A
