Hello,
I have a BU40N that is currently on 1.02 and looking to flash to 1.03. My MKV details are below. I downloaded the all you need firmware file and the gui sdf tool. However after selecting the drive and proper file I click start however nothing happens. I tried on two computers and same result. It did work when I updated an internal drive LG WH16NS40,. So for the BU40N is there any known issue or additional steps other than using the tool selecting drive and file ad clicking start? If tool is an issue would cmd commands work?

What is the brand/Mfg of the chassis the drive came in? If it's Archgon, the chassis is junk and flashing doesn't work with that chassis. The drive can be removed and flashed with an adapter or in another chassis.

Thanks,
Frank

Yes it is archgon case thanks for providing the reason it would not flash. Will look at other case etc.

I purchased this drive from Amazon, removed the included drive & swapped in the drive from the archgon unit. Paid about $18 USD:
External CD/DVD Drive for Laptop, DVD Burner CD Reader for Laptop, 8-in-1 USB 3.0 Portable CD Players with SD/TF Ports, External Disk Drive Optical for MacBook Windows 11 10 PC Linux OS

Thanks,

LG 16NS40. Successfully flashed to HL-DT-ST-BD-RE_WH16NS60-1.02-NM00100-211810291936.bin using the GUI flash tool. Here are the current reads on the drive from MakeMKV.

However, when I put a 4K disc in it just chugs for 10 minutes and then goes back to "No disc inserted."

Is there something I'm missing?

Thanks.

Make sure you have completely powered off/disconnected the drive after flashing (not just rebooting computer).

Make sure the disc is clean, even if it is new and/or looks clean. I've had fresh out of the box new releases that I needed to clean before I could rip them.

Thanks,
Frank

What was the MakeMKV drive info and libredrive info sections before you flashed it?

Is it an older, pre 2016 model? If so, it's probably the older, incompatible MT1939 drive platform.

It said MT1959 before I flashed it. It was on base 1.0 factory firmware. I did a full power cycle on the drive (which is in an external enclosure). The flash executed perfectly and updated to the information I posted.

I didn't have the thought to screenshot the before info. But LibreDrive was all good, it lined up with everything that the tutorial said I needed to have and have ripped many of my 1080p Blu-Ray discs with this setup.

Can it still rip standard blu-ray discs?

If it is manufactured after Oct 2015 (check the label on top of the drive) and MT1959 drive platform and was on an original firmware v1.02 or lower, it would already have been libredrive enabled and UHD compatible without the need for flashing.

Okay. So that sucks.

Womp Womp. Found the problem. I've got another one of these drives that's newer in another machine. Flashed it directly to 1.02MK today and it worked perfectly. Thanks for the help!

I recently received a new LG Slim - WP50NB40 - Manufactured Jan 2026
I read the first post in this thread that indicated to go to > BP50NB40-NB50-1.03MK then to > BP60NB10 1.02MK or 1.00MK

So I was able to flash first (using the SDFtoolFlasher GUI tool) to the 1.03, it then showed no longer encrypted.. and then to the BP60 1.02

am I missing a step? I'm interested that I used the tool to write the BP60NB10 1.02 from the All You Need firmware pack... however in the LibreDrive is still says 1.03? is that expected? Any help?

Carefully follow the animated GIF/video on the first page of SDFtool Flasher thread. You must select a firmware three times. Pay attention to the animated GIF & when/where a firmware is chosen, and what firmware is chosen. You probably selected the wrong firmware in the recovery step (I've done this in the past).

Thanks,
Frank

I run Debian Linux and had MakeMKV 1.18.1 and 1.17.3 on my machine, following the guides linux instructions pointed me at the following:

sdf.bin

I extracted out the All you need firmware and under 'Slim External Drives' I found the firmware: DE_LG_WP50NB40-NB50_1.03_MK.bin I copied this and sdf.bin to /tmp
I confirmed via MakeMKV I had Drive platform: MT1959. Running the following command:

I have 4 different 4k Bluray films (bought at various times with the standard Bluray), inserting the standard Bluray, makemkv is able to see and rip from the disc, inserting any 4k BluRay results in the disc being spun and restarted multiple times until no disc has been found.

I've read through the instructions and noticed the post above saying I'm at the half way point, but after the linux instructions it goes to troubleshooting for errors I am not seeing. I also tried watching a few of the videos but I can't see what I have done wrong.

Does anyone have any suggestions?

I'm not sure, but was or wasn't your firmware encrypted to begin with?

not sure this works better, but maybe

Code: Select all

/opt/makeMKV/makemkv-bin-1.17.3/bin/amd64/makemkvcon f -d /dev/sr0 -f /tmp/sdf.bin rawflash enc -i /tmp/DE_LG_WP50NB40-NB50_1.03_MK.bin

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.
