Can you flash the OEM drive with the usual 4163B firmwares from LG’s site. It says on the site that you shouldnt.
I have an oem L.G. 4163B and I flashed it to A105, no problems. I did however take the precaution to disconnect my other drive from the ide cable before flashing, to make sure it was the only drive recognized.
LG is referring to OEM drives sold by Dell and the like with modified firmware. Most OEM drives we refer to here are sold by Newegg and similar sellers without box or software. Other than some BenQ and Pioneer drives, , these OEMs use the same firmware as is found on the factory website
