Sony dru 810ar flash

just purchased a sony dru 810ar i have seen that this is a rebadged benq 1640
what firmware should i use on this unit?

:cop: WARNING! :cop:
Sony shipped a DRU-810A (Benq 1640 clone) and a DRU-810A-R (Benq 1650 clone). If you croshflash it to the wrong Benq firmware, the drive will be dead. There are several threads about this topic, e.g. here. Read them carefully and keep in mind that you can easily kill your drive.

Thanks Ala42 you probaly just saved this drive i would of flashed with the 1640 but seeing it’s the ar it needs the 1650 firmware bookmarked the link (thanks)
