Well at first I thought it was these ones: http://digi.firmware-flash.com/165_166.htm , but now my drive doesn't work. It could be coincidentally, because I think something might be broken physically and I plan on RMAing it, but before I do I want to make sure it's not just because the firmware is for the wrong drive.
I ordered it from NewEgg, and on my Invoice this is what is listed: DVD|LITE ON 16X LTD-163/LTD-165 RTL.
I know I know, I should've backed up the firmware before I flashed, but nothing we can do about that now. Anyways, before I flashed, in device manager it simply said "Lite-On 165H" something like that I think. But now it say JLMS DVD-ROM 165H... I'm thinking that maybe that's why it's not working, although again it could be that the drive is physically broken.
