Edge-V PRO Dead?

Hello. My problem is, that three was a power failure while I was flashing v pro. And it is now in the state - no video, can’t boot sd, mor nvme. Only red LED light is on. When I press and and hold “R button”, blue led lights-on and stays about 10 to 20 seconds. Please, is there a Sollution or is the board “dead”?!

Thank You,

@prikin78 Can you try boot into upgrade mode with MRegister ?
