I am trying to crossflash my Lite-ON DH20A4H to a DH20A4P. Currently I have the QP5B. I backed up my EEPROM and ran Flash Utility 6.0.1 (so as not to get the error with the original Lite-ON utility that there's a model mismatch), but after flashing, the drive's light is just blinking, even after a power cycle.
Flashing back to QP5B fixes all the problems.
My question is, if the only difference between the DH20A4P and the DH20A4H is lightscribe, shouldn't the crossflash take?
Oh, the reason I want to crossflash is because there's a piece of Software called "BurnerMax" that sends a signal to the drive to increase the recognized disc space on dual layer DVDs higher, so that you're able to burn XDG3 titles for Xbox360. For some reason, the program won't work with QP5B, but it does work with the DH20A4P's 9P59.
I used codeguys' firmware referenced in this thread:
These guys do an amazing job.
Onem ore thing, I have an "A" laser drive.
