ASUS BW-16D1X-U A105 MT1959 - SDFTool 0xFF05C103 flashing WH16NS60 1.00

[wells217]

Hi all,

I'm looking for advice on a 2026 ASUS BW-16D1X-U (MT1959) drive. My primary goal is DVDFab compatibility. MakeMKV already works correctly.

Original drive:
- Model: ASUS BW-16D1X-U
- Original firmware: A105 (encrypted)
- Platform: MT1959

Using SDFtool Flasher v1.3.6 I:
- Successfully dumped the original firmware:
dump_user_ASUS_BW-16D1X-U_A105_212012021114_KLXPABE3417.tar
- Successfully flashed:
DE_LG_WH16NS60_1.02_MK.bin

The flash completed successfully.

Current drive:
- HL-DT-ST BD-RE WH16NS60
- Firmware: 1.02
- LibreDrive: Enabled
- Firmware type: Patched (microcode access re-enabled)

MakeMKV reports:

Manufacturer: HL-DT-ST
Product: BD-RE WH16NS60
Revision: 1.02

LibreDrive Information
Status: Enabled
Drive platform: MT1959
Firmware type: Patched (microcode access re-enabled)
Firmware version: 1.02
DVD all regions: Yes
BD raw data read: Yes
BD raw metadata read: Yes
Unrestricted read speed: Yes

The drive reads UHD discs perfectly in MakeMKV.

Problem:

DVDFab 13.0.6.5 detects the drive and starts reading the UHD disc, but then immediately reports:

"Failure opening the disc due to the unfriendly firmware installed on this drive."

To make it DVDFab compatible, I attempted to flash:

DE_LG_WH16NS60_1.00.bin

using:
- SDFtool Flasher v1.3.6
- WRITE Firmware
- Include boot loader unchecked
- No disc in the drive
- DVDFab and MakeMKV closed

When I click START, SDFtool immediately returns:

0xFF05C103

No firmware is written.

Questions:

1. Is DE_LG_WH16NS60_1.00.bin the correct firmware for a 2026 ASUS BW-16D1X-U (MT1959) whose primary use is DVDFab?

2. If so, what is the correct procedure to transition from WH16NS60 1.02 MK to WH16NS60 1.00?

3. Does error 0xFF05C103 indicate that a different flashing method or tool is required?

4. Would restoring the original A105 firmware dump first be a valid stepping stone, or is there a different recommended procedure?

Any guidance would be greatly appreciated. Thank you.

Pretty sure that error is for a disc in the drive. Ensure there is no disc in the drive and the tray is closed.

The firmware dump you have is not the full firmware. It is only the important user cal data and cannot be flashed to the drive. It might be best to reboot the drive and your PC to ensure that all DVDFab products are not running (even in the background).
