I have a wd10tmvw
usb 3 board
with pins for the serial port
I cant read the rom
So then I pull the board to read it with a pin reader
and there is no U12
only U14
board is 771814-001 rev P1
trying the usual com port and usb reading finds the cpu but cant find an internal rom....

drive went to another shop
