Some info on firmware downgrading the drive from the MakeMKV wiki is available here.

Known good LG/Asus BD ODDs were initially recommended to be flashed with Asus BW-16D1HT 3.02 (DE - Downgrade Enable), especially ODDs using PCB: JB8 2015.05.08 (Reference Image)) The 3.02 (DE) firmware supports Lead-in and the OpCode 0xf1[1][2] (normally used by Plextors to read the EEPROM, but in the case with Asus BW-16D1HT 3.02, it reads the cache) to read 1 sector[3] of Lead-out through cache.

On 2022-04-04, RibShark released a hacked version of the 3.10 firmware that enabled lead-out reading without using the cache.

Flashing Instructions

From here and below, this guide will focus only on JB8 2015.05.08 ODDs.

Requirements (before BW-16D1HT 3.11)

Some notes before you begin

  • After each file have been sucessfully flashed, it's a good idea to power cycle the ODD, either by disconnecting the SATA Power cable (wait at least 15 seconds before reconnecting) or by restarting the computer.
  • Specific instruction for GNU/Linux(-libre):

sudo wine ASUS_ODD_FW_Changer_-_FIRMWARE.exe

General Process

  • First, make sure MakeMKV is installed: https://www.makemkv.com/download/
  • Next, download the SDFtool Flasher (updated version) from this thread in the MakeMKV support forum: https://forum.makemkv.com/forum/viewtopic.php?t=22896
  • Run the SDFtool Flasher.exe, and it will open a dialog box. Select your ODD (drive) from the first drop-down menu.
  • Click the second drop-down menu, 'Please select a Firmware to Write,' and choose the firmware from the list below, depending on your drive/firmware combination.
  • If the drive currently has an encrypted firmware (e.g. 3.11, check the encrypted firmware list here), ensure there is a green checkmark next to 'Encrypted Firmware.' If there isn't, click on the Red X to make it a green checkmark.
  • Then click S T A R T and it will start flashing the firmware.
