So unfortunately i have a liteon 0401. I was planning on following the unlocked replacement PCB route which costs 60-80. I was wondering however if maybe replacing the DVD drive entirely would work since it seems to be more cost efficient - a benq VAD6038 goes for around 30. If this does work, what drives would you recommend i swap it out with/which are the easiest to flash? And is there anything i should watch out for (specific FW vers.) when buying a new DVD?
