JLMS XJ-HD166S damn firmware!

Hi all, I’ve been trying for a few days now to get this damn drive working correctly. It seems to read audio cds correctly but not software and has also given up reading dvd media. I’ve tried various firmwares, and had to flashfix it originally as it wouldn’t flash at all! I can’t even find a driver for it from the JLMS site as it seems that doesn’t exist anymore :doh:
PLEASE help before I put this in the bin :sad:

Test it in another computer or boot from a DVD. If it doesn’t work, the dvd part is dead.
Flashing never can resolve such hardware errors.
