i recently upped my firmware to qs05ea (or whatever it is!) this gave me loads of trouble and so after reading about many other users having the same problems i managed to flash my drive back to qs0B. although everything works fine i can no longer play audiocds! every other type of cdr cdrw etc works perfectly. ive tried to upgrade and downgrade again using LTNFlash. i didnt even know about the bootcode option until later… so i was afraid i may have screwed up the calibration data but im prettty sure my drive is a first revision as it came with qs0* firmware and a manufacturing date of Aug. 2003, and of course most discs still work so im assuming that isnt my problem. does anyone have any ideas that could help?
ta in advance
