You should not cross-flash these drives. So many people have been unable to flash back to BC-12D2HT firmware. There is no need to cross-flash this model. Firmware BC-12D2HT_3.11-MK is UHD friendly.

Have you tried flashing this firmware?
Cheers :D

I am thinking to dump the crossflashed bw-16d1ht firmware modify BC-12D2HT FW using calibration data and key from the dump, then dosflash using firmware for BC-12D2HT with exported data. Will it work??

Dos flash is semi permanently disabled 3.10+ so no dumping the firmware there are ways around it but not worth.
It will work fine with that firmware probably better

So, I have succesfully flashed back Asus 12D2HT firmware using dosflash. I have found clean 3.00 firmware for it and modified using data extracted by eeprom data mover from my dump of BW-16D1HT crossflashed firmware.
I have used very old mediacenter pc SATA IDE mode (only available on it - no ahci there) and Win8PE booted from usb. Used Dosflash 2.0. First I downgraded BW-16D1HT 3.10 to 3.02, then to 3.00 using modified asus flasher. Booted winpe and started dosflash. It found drive no problem. Readed dump no problem also, zero errors. Then i modified clean 3.00 BC-12D2HT firmware using my dump and eeprom data mover and flashed it. Flashing went without any problems. So basically theory about permanent dosflash disabling after touch of 3.10 FW can be put between the shelves.

After reboot, drive appeared back as Asus BC-12D2HT 3.00 unmodded.

So basically i purchased drive BC-12D2HT 3.11 then crossflashed to BW-16D1HT 3.10, downgraded to 3.02 and then 3.00 and converted back to BC-12D2HT 3.0 using data from the dump. And at the end flashed 3.01MK to make it uhd friendly. A bit to much hassle, but i did not know there is 3.11 mk firmware for it when i was crossflashing. I will let you know tomorrow if everything is working as supposed to. For now i only have cdrw and normal cd to test. Tomorrow i will organise some bluray 4k discs.

Pictures attached. Also pack of all required files if someone had the same problem of course without my dumps and created fw.
