M10 octacore android box won't turn on

[AC Question]

Attempted to update my firmware with an SD card.
once i did the reset button and plug in the power cord it was frozen with the MBOX logo on the screen for 10-15 minutes without any status bar or anything. Now when the box is plugged in, the blue light on the front flickers only once and then nothing.
Did i kill my box? is there anything i can do now?

Thanks,
Ryan
