IHAS324 W HL12 Region Free

I have this Liteon drive and could not get any of the utilities to work to make it region free but in the process found out it had a NEC chipset.
I managed to dump the firmware bin file with NECwinflash.exe but it would not change the RPC2 setting to RPC1 so I manually hex edited the bin file and successfully made it a RPC1 drive. Did not know if anyone wanted a copy of the bin file for there drive. If you do let me know.
