Riplock for Liteon ATAPI_DVD_D_DH16D3S DVD-ROM



I have the Liteon ATAPI_DVD_D_DH16D3S DVD-ROM drive for half a year.
I get rip of the region code, but the riplock is still here, and the omnipatcher won’t work on new drives.
I want to know if there is any way for me to get rip of the rip lock also, so can I can use the drive to read DVD disc at full speed. I try to find it all these months, but no luck so far.:frowning:
Any help would be appreciated.
