Ultimate UHD Drives Flashing Guide Updated 2026

[nicholfd]

Hello all. Thought I'd post in this thread rather than opening a new one, but if it's preferred I post a standalone thread, I'd be happy to.

I am attempting to flash a Buffalo BRXL-16U3 on a Mac.

Code: Select all

Drive Information
Manufacturer: HL-DT-ST
Product: BD-RE BH16NS58
Revision: 1.03
Firmware date: 2120-05-08 09:33
Bus encryption flags: 1F

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

I paid attention to the first post of this guide and downgraded my MakeMKV and downgraded my MakeMKV to 1.17.7 (I bought a license to satisfy the prompt that said I needed to. Afterwards the initial launch would say that the program failed, though it still started up alright).

I moved the

Code: Select all

sdf.bin

file and the version of the firmware that my searches of the forum indicated I should use

Code: Select all

HL-DT-ST-BD-RE_WH16NS60-1.02-NM00100-211810291936.bin

to the /tmp directory and fired up the CLI to get the drive ID

Code: Select all

$ cd /Applications/MakeMKV.app/Contents/MacOS
$ ./makemkvcon f -l

After that I ran the full command:

Code: Select all

./makemkvcon f -d '/IOBDServices/B16D63D6' -f /tmp/sdf.bin rawflash main -i '/tmp/HL-DT-ST-BD-RE_WH16NS60-1.02-NM00100-211810291936.bin'

Which completed with a "Done successfully"

Then I reinstalled the latest version of MakeMKV (because of the fatal error bug) and unplugged the drive and plugged it back in. But the firmware remains the original version.'

Happy to try again or take a new tack. Can I just use 1.18.3?

No need to downgrade or use an old version of MakeMKV on macOS. It's great that you bought a license of MakeMKV - need to support those who support our hobby. I'm not aware of any requirement to buy a license to use the tool, as long as you have a current/non-expired "beta" key.

That drive has encrypted firmware. You need to use the encryption option ("enc" I believe - check the instructions).

Thanks,
Frank

Hi, I'm trying to flash my BU40N but getting "No drive tool logic found in SDF.bin" on both Windows and Linux with the latest sdf.bin from makemkv.com.
Drive info:

Drive: HL-DT-ST BD-RE BU40N
Firmware version: FR07
Firmware date: 2118-01-22 15:36
Platform: MT1959
Bus encryption flags: 1F
Highest AACS version: 72
Serial: 808HS043042

What I've tried:

Latest sdf.bin from makemkv.com
sdf_000000a5.bin extracted from appdata.tar
Both Windows (makemkvcon64.exe) and NixOS Linux (makemkvcon)
Firmware file: HL-DT-ST-BD-RE_BU40N-FR07-JM02202-211801221536.bin from the 2020 firmware pack

Is the FR07 variant supported? Is there an updated SDF.bin or alternative method I can try?

If using Windows, why not use the SDFtool at the start of this thread? Install latest/current MakeMKV in the standard location, make sure it has internet access & launch it once, connect the drive & launch the tool. Select the drive, select the firmware & click Start. No need to mess with "SDF.bin" - it just uses what the MakeMKV app downloaded, and for the BU40N, I suspect that hasn't changed in a long time.

No need to downgrade or use an old version of MakeMKV on macOS.

Ah, I see now, the downgrade is only necessary for linux. I misread that as Mac/linux:

Mac/linux commands to flash. the latest working version is 1.17.7 of makemkv for flashing do not use an newer version for flashing until further notice on linux

That drive has encrypted firmware. You need to use the encryption option ("enc" I believe - check the instructions).

Good to know, I hadn't seen it in the list so wasn't sure about that.

It might be cool if the

Code: Select all

makemkvcon info

command could include information about whether a drive has encrypted firmware or not.

I'm certainly grateful for the quick response from Billycar11 and you, Frank, but I wonder if it might be a good thing to help newbies fall into the pit of success.

Is the utility open source by chance?

At any rate, everything looks good to me after using the correct command So thanks all!

Code: Select all

./makemkvcon f -d '/IOBDServices/B16D63D6' -f /tmp/sdf.bin rawflash enc -i '/tmp/HL-DT-ST-BD-RE_WH16NS60-1.02-NM00100-211810291936.bin'

makemkvcon is the command line part of MakeMKV - not open source.
