Ultimate UHD Drives Flashing Guide Updated 2026

[Billycar11]

Hi folks,
Apologies if this is the wrong place to ask... I'm new to the forum and Makemkv.
I have the following drive, which from what I've read here I think I should be able to flash with revised firmware to enable Libredrive. Where I'm unsure is which fireware I should be using so I would appreciate some pointers as you where to look.

Drive Information
OS device name: F:
Manufacturer: HL-DT-ST
Product: BD-RE BU50N
Revision: GE03
Serial number:
Firmware date: 2119-04-23 16:48
Bus encryption flags: 1F
Highest AACS version: 68

LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959

Can I also check that I should use the SDFtool flasher and lastly do I just flash the new firmware or should I be backing up the existing drive forward first.

Sorry for all the probably obvious newbie questions and thanks in advance for your help.
Mike

Treat it as a bu40n
Backups are not needed

Or email me or Marty for an automated flasher

Many thanks for your help. That's worked perfectly

The guide in the first post is great. I deeply appreciate the effort and work BillyCar, MartyMyNuts, et all put in. Really excellent. But it's also very generalized. So here is what I did, using their work, to get my specific drive working. The hope is just to help people with the same setup have more specific directions. (Or maybe just for me if I have to do it again ever)

The drive is a WP50NB40 "LG Super Multi Blue Slim Portable", service code NB52. Flashing from a Mac on Tahoe 26.2.

This zip file has all required files. (MakeMkv 17.7, the two firmwares, sdf.bin). Copied out of the first post, just the ones you need, in one place. - https://drive.proton.me/urls/1HPEN2MT1W#9N7T0ZFU5SdL

1. Install the old (17.7) version of MakeMkv. Try to open it, get the security warning, bypass the warning in "System Settings -> Privacy & Security -> Open Anyway".
1.b. It won't actually run after that. Just crashes when you try. Doesn't matter. We're just going to be using a utility installed with it, from the command line. When we're finished with the flashing, we can remove this old version and use the current version.

2. Open the terminal. Change your working directory to /Applications/MakeMKV.app/Contents/MacOS/ ( "cd /Applications/MakeMKV.app/Contents/MacOS/" )

3. Run the command "./makemkvcon f -l", copy the part that says "/IOBDServices/XXXXXXXX" to notepad.

4. Copy the two firmwares and sdf.bin (from attached zip) to /tmp ( "cp 'path to where you extracted them' /tmp" )

5. Flash the first firmware, "HL-DT-ST-BD-RE_BP50NB40-NB50-1.03-NM00800-212005070917.bin". The current firmware is encrypted, so the command is the second one in the guide.
5.b. It's easier to write the command in notepad, and copy it into the terminal. So copy this, replace the XXXXXXX with the numbers you copied earlier, and then paste into the terminal.

Code: Select all

./makemkvcon f -d '/IOBDServices/XXXXXXXX' -f /tmp/sdf.bin rawflash enc -i /tmp/HL-DT-ST-BD-RE_BP50NB40-NB50-1.03-NM00800-212005070917.bin

6. Unplug the drive, wait 5 seconds, plug it back in.

7. Run "./makemkvcon f -l" again, if the numbers changed, copy them into notepad again.

8. Flash the second firmware, "DE_LG_BP60NB10_1.00_MK_HBD.bin". It's no longer encrypted, so use the first command from the guide.
8.b. Do the whole copy it into notepad, paste into the terminal dance again.

Code: Select all

./makemkvcon f -d /IOBDServices/XXXXXXXX -f /tmp/sdf.bin rawflash main -i /tmp/DE_LG_BP60NB10_1.00_MK_HBD.bin

9. Unplug the drive, wait 5 seconds, plug it back in.

10. Install the latest version of MakeMkv, see your UHD.

Thank you for posting this, the main guide is a fantastic resource but I was struggling to get through the flashing using a Mac until I found these extra steps. I ended up needing to use a combination of these steps as well as some I found on this Reddit post (https://www.reddit.com/r/makemkv/commen ... _on_macos/) to get a successful install.

I'll share some of the details of my install in case it helps anyone in a similar situation:

• Drive: LG BP50NB40 external slim, SVC code NB52

• Computer: Macbook Air running Tahoe 26.3

To get my install to work, I needed to follow the steps in the above post up til step 5, then I couldn't get beyond that step until I cycled through the enc -> main -> full flash commands for the same firmware like called out in that Reddit post I linked. After that, I was able to flash to the BP60NB10 version and update MakeMKV back to the latest version (before that I kept getting silent failures, where the terminal window would say firmware was updated successfully but opening MakeMKV woud still show the BP50NB40 version).

Also, another problem I ran into - new Macbooks only have two USB-C ports, vs the cable for BP50NB40 with two USB-A plugs. I tried using USB-A to USB-C adapters, a micro-USB to USB-C cable to connect the drive directly to the laptop, and connecting the extra USB-A plug to a 5V wall adapter, but my rips kept failing partway through and throwing errors related to insufficient power, especially when I was trying a 4K disc. I finally broke down and bought a USB hub with an external power supply, and so far that seems to have fixed the issue.

Hi there!

I have heard great things about the MakeMKV program, so I am quite excited to get started ripping my bluray collections with MakeMKV.

But before I can do this, I have to flash my ASUS BW 16D1HT bluray drive.

Unfortunately, my only Windows system is a laptop.
I have gone through the guide, and I read this should be possible, but there are some limitations.

I read the flashing can be done through certain USB adapters, so specifically for this purpose I purchased the BENFEI SATA to USB 3.0 Cable as specified in the "Ultimate UHD Drives Flashing Guide Updated 2026".

At this time, I have not flashed my drive yet, but instead I have dumped the firmware with the SDFtool and the tool gave it the name:
dump_user_ASUS_BW-16D1HT_3.10_211901041014_KLZKC7E2418

According to the SDFtool I am currently using an unencrypted ASUS BW-16D1HT 3.10 firmware for the drive. So, to make sure, can I just flash my drive straight with SDFtool and the ASUS-BW-16D1HT-3.10-WM01601-211901041014.bin image from the all you need firmware pack?

I am a newbie and I just want to run this with you to make sure I got all this, correct. Thanks!
