We got repeated  ERR 0555 and DSC error messages. 
We updated the firmware 
Firmware updated says K3 Bootstrap loader did not echo “D” remove power and try firmware load.
I removed power and sent all firmware to K3.
K3 now is in a state where the display is dark and shows MCU LD and the TX led is blinking 
Removing power does not get it out of this state. Need expert advise asap,
Thanks
