DA-prefixed board numbers like this follow the Quanta scheme, so Quanta made the board. Write the image to the SPI flash with a programmer to recover a dead or bricked board. Confirm the PCB board number and revision first, back up the original chip, and check the image size matches the flash chip capacity.
