I am about to attempt to crossflash a Philips DVD8801 drive to BenQ DW1650, probably with the BCHC firmware that was just released.
I had previously succeeded in crossflashing a few Philips DVD8xxx drives (OEM only?) to BenQ counterparts, but I am currently not 100% sure the DVD8801 hardware matches that of BenQ DW1650, though I believe this is more likely compared to, say, DW1640. Here's my logic:
DVD8601 --> DW1620 OK
DVD8651 --> DW1625 OK (Lightscribe)
DVD8851 --> DW1655 OK (Lightscribe)
DVD8801 --> DW1650 ??
Hopefully my next post will be good news of success.
