“Hi. Maybe you will be able to help me. I have crossflashed Asus BC-12D2HT with ASUS BW-16D1HT fw and have a problem to go back. I want original firmware but UHD friendly. The drive originally came with 3.11fw. When i try to flash original fw using asus flasher i am receiving error 5. I can go up and down with ASUS BW-16D1HT fw (even to 3.00) but cant go back to Asus BC-12D2HT fw.

I am thinking of dumping the crossflashed firmware, extract the laser calibration and encryption key data and modify clean Asus BC-12D2HT fw and flash using dosflash. Is dosflash have similar limitation as asus flasher? Or it will flash whatever you give to it?? Would you be able to help me prepare such a fw? If this method is not possible will the drive work properly on ASUS BW-16D1HT fw? Will be grateful for any help.” - from user on forum.
