I have bought a new BH12LS35 from best buy 5 months ago, after burning around 20 bluray disks very smoothly, the drive started to give me some burn failure on some disks , then the drive gives me fail burning to all bluray disks (with power calibration area error), however,it can read blurays and read & write DVDs and CDs effectively. I have tried so many solutions I found on the internet include changing IMAPI setting, burning speed, disks type, PCs, OS, burning softwares, fixing tools, with no benefit . finally, I have updated the firmware to 1.01(from firmware HQ) with NO benefit, then after chatting with many LG support and professionals, I figured that the laser may be defected so soon and they request to send it back for checking. I decided not to waste more time with this headache and I will return it back to LG repair center, but before that I need to return the firmware to the original one (1.00). I have not backed up my original firmware , I don’t know how to return it back.
can I use any BH12LS35 firmware 1.00 from other similar device. If yes please help me and provide me with tested original one to get my money/drive back.
thanks a lot and waiting for your help
