[QUOTE=troy512;2143156]please download flash utility
from here finding firmware is easy??[/QUOTE]
it was not possible for me to use this fw:
But Steve and Mike K sent me their fw backups (ver.8H1B) - both files are binary identical.
I used this firmware backup and … My drive is WORKING AGAIN !!! EEPROM backup was not necessary.
Then I used this one upgrade from HP site and it worked too:
But, strange thing is, that I’m not able to upgrade firmware to newest one (ver. 8P55 - from LiteOn site) - it says:
[B]No matched drive detected !
This utility is only for ATAPI DVD A DH16A3L drive.
1-1-0-0 H:ATAPI DVD A DH16A3L 8H1F[/B]
I see one added space between ATAPI and DVD in my drive ID, probably that’s reason why LiteOn fw can not be flashed to my(our) drive.
That’s probably because in our HP bundled drives is modified firmware by HP.
There would help extracted/unscrambled .bin firmware (ver.8P55) from not rebadged (not HP) drive.
Anyway, BIG THANX again, Steve and Mike.
