My sincerest thanks to all that replied and offered some sound advice and links.
I have used these tools myself today and backed up my EEprom and firmware.
I then flashed the drive with the two backups and burned a DVD with my Liteon 812S.
The burn went perfectly, I now know how to do with the advice I've received.
Pbrynt's main concern is if a rebadged unit will behave the same as a retail or OEM Liteon 812S. Are the specifications the same and no damage can be done from going from the UTS2 firmware to the USOQ, that is the only question that needs to be answered now. The backing up of the original EEprom and firware will pose no problem.
Edited: Just learned from COdeKing that to the best of his knowledge the rebadged Liteons 812S with the UTS2 firmware can be updated to the USOQ.
