SHM-165H6S cannot change bitsetting

[qanda]This thread is about the Lite-On SHM-165H6S. Click here to see full specs[/qanda]I tried the liteon utility, and it returned “Firmware not support”
what should i do

Did you try the Book Type Utility? If you tried the Omni-Patcher, it would likely give some error message since Omni-Patcher only works on LiteOn 1693 and older models. Which firmware is currently used?

The 165H6S should do bitsetting on DVD+R DL discs by default, you can use Nero CD/DVD Speed or Nero Disc Speed to check the current settings. with this tool you can also change the booktype setting.

give it a try

OK! i did it, heres what the problem was:
my drive was reading as having firmware HP16 (probably OEM from HP) so i just had to manually change the firmware to the latest. the standard Liteon update didnt work either, had to use liteon patching utils. after that it worked fine

Glad to hear that you solved the problem, and thanks for letting us know the solution.
