    Yes, make sure that MacProEFIUpdate.dmg is mounted before running the Firmware Tool.

    If you did not get your problem resolved, I would check OS. No success under 10.11.3 but 10.7.5 worked. Remember to have the Apple 5.1 firmware update mounted as well (and not the B07 firmware like some idiots did. like myself)
