I had been facing this problem for sometime now, in some places where I guess the power fluctuate the android image get stuck after re-booting. Like today when I was trying to add another USB device to BPI which sucked the power out and BPI shut down unexpectedly. After that it would not restart, I only get to see the Green Android image and after that the screen goes blank.
FYI: I am using BPI-M1 and Android 4.2 image; please please help me, I already have my devices rolled out to my customers and they are after my throat to get that fixed.
Any help is appreciated.
Thanks in advance
