Problem when changing liteon dvd from patch firmware to official one

After the release of liteon dvd prc utility, I want use official firmware.
But when changing liteon dvd(ltd-165h) from patched(prc-1) firmware to official one(ch0q), it can’t work.
Litefirm can’t extract the exe file to bin file. how to solve the problem?

Turn the region coding back on and then flash with the Windows flasher maybe…

You can get a binary CH0Q at http://digitri.tk (say thanks to Mango for it!) :slight_smile:

Litefirm, not even version 2 in the firmware forum, can extract DVD firmwares because of the 64k header thing. You have to get someone to flash their drive and then back it up. Airhead gave you a source though, so there you go.
