My board decided to crap its pants after flashing armbian for the 10th time but I managed to revive it.
Not sure if this is useful but I found the clock pin that I can connect GND to make the box enter MASKROM mode my board has an emcp chip on it
My model is MXQPRO_V71
you can solder a wire to this point and short it to ground then plug in your sdcard with multitool
short the clock pin to the ground and plug the power, wait till the led indicator turns red then remove the jumpers. if the led starts flashing then you are all set! you can try flashing armbian or your stock firmware to your box
