Firmware archive, 2.81 MB ZIP, whose name points to a V400 and the board marking 71R-A14HV6-T840.

Compare the board code printed on your PCB with this one, and check that the image size matches the capacity of the flash chip. Dump the existing chip with a programmer before reflashing, so you can roll back if anything goes wrong.
