Ultimate UHD Drives Flashing Guide Updated 2026

[MartyMcNuts]

I am trying to do this process for BP50NB40. In the section it mean BP50NB40 to > BP50NB40-NB50-1.03MK and ...> BP50NB40-NB50-1.03MK with enc. Where do i find the with enc and the BP50NB40-NB50-1.03MK with bootloader/full flash as well.

The easiest way is to use SDFtool Flasher and follow these steps.

1. Flash the drive to BP50NB40 (NB50) 1.03-MK.

Now for the crossflash:

2. Select the RECOVERY option and in the pop up, select the BP50NB40 (NB50) 1.03-MK firmware that you just flashed.
3. Select the BP60NB10 1.00-MK or BU40N 1.00 firmware that you want to use in the normal drop box.
4. Click START

So for the Buffalo BRUHD-PU3-BK, I used the SDF 1.3.5 flasher on "write", loaded HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin and hit start. Is that all there is to it?

pretty much you might have to do enc depending how new your fw is think bu13 and up is not sure haven't seen those in a bit

Yep. MakeMKV should now show the drive as BU40N 1.03

I have a really noob question and I apologize for asking.

But essentially, I just need a flashed drive to rip my UHD movies? And would I need a second one to do regular BD's, or is one enough?

I'm just too do this for the first time and I'm pretty clueless so wanted to ask the people that know their stuff

Anything recommended in the 1st post will handle DVD/BD/UHD.

What is enc? encryption? What is that all about? thanks.

It doesn't. Is this a problem?
it reads it as BD-RE BUFFALO OPTICAL Drive 1.03

When flashing with SDFTool there is a checkbox called "enc" you might have to check it or not. Try both scenarios. One will succeed and the other can't do any harm.

It seems no matter what I do (tried the all in one fw and the MK fw (japan) and the drive just continues to read:
Manufacturer: BUFFALO
Product: Optical Drive
Revision: 1.03
Firmware date: 2118-10-24 19:34
Bus encryption flags: 17
Highest AACS version: 78

Your done it will always read buffalo the case injects it own name mike had to work around that for flashing and drive recognition.

Your drive did not come on 1.03 it cam on bu13 or something like that

Hi all, my old ASUS drive just died, so I decided to upgrade to a UHD drive, and I bought a Hitachi-LG BU40N.
Reading the pinned post at the beginning of this thread, it seems like I'll have to flash its firmware, which I'm OK with. My question is the following: I read that "The only flasher anyone should be using now is Martys SDF GUI"; is there an alternative for Linux users, or must I do the flashing on Windows?

Cool, thanks!
Just to be 100% sure, I assume the firmware will be encrypted, and so I'll use the rawflash enc option to flash the 1.03MK. But would it allow downgrade, if my firmware is, say, the 1.04? (I don't know the actual version yet because I haven't yet received the drive).

Hey guys,

I apologize if this seems like a very rudimentary post asking these questions. I've been using MakeMKV for years with Blu-Ray and never had any issues with it. But now that I bought a BP60NB10 LG UltraHD drive and learned there is this whole firmware situation (why even sell a UHD player if it won't even play the disc???), I've been trying to make sense of these exploit instructions.

I downloaded the sdftool and the makemkv firmware pack that has been recommended by most, but I'm unsure which file to use. It just reads like Greek to me.

Again, sorry if this seems like someone who's just an amateur (which I guess I am), but I have an extensive movie collection that I would love to finally be able to rip those 4K discs that have been sitting on my shelves and it's weird that this would be such an immediate and senseless roadblock.

All of the other details seem correct too. MT1959 Drive platform and such.
