can i flash a dw-q28a with dru-800 firmware? thanks.
yes, but liteon 1693s firmware KS09 is newer than KY03 for the 800a.
Yes. See the Sony DVD Burner overview thread at the top of the forum.
@chok0 - Why did you link to the crossflash firmware? Crossflash patching is needed only for 1673S/720A/D26A -> 1693S/800A/Q28A
