Ultimate UHD Drives Flashing Guide Updated 2026

Not sure what happened but the link in the initial post to the SDF.bin doesn't work anymore for me unless you add the www. to the domain name. I.e https://makemkv.com/sdf.bin doesn't work for me but https://www.makemkv.com/sdf.bin does.

Hi all, thanks to the OP guide I downgraded correctly my BH16NS55 from 1.03 to DE_LG_WH16NS60_1.00.bin
Prior to flash the DE_LG_WH16NS60_1.00.bin I flashed the WH16NS60 1.02MK as per encrypted firmware:
BH16NS55 on any Firmware directly to > WH16NS60 1.02MK

And everything should be ok. Thank you so much for the guide!!!

My question now is regarding other driver I own:

Product: BDDVDRW CH12NS40
Revision: 1.01
Firmware date: 2117-11-21 16:06
Drive platform: MT1959
Firmware version: 1.01

For that drive, there is no references on firts post, so, can I use the same procedure I used with BH16NS55? :
1) Flash WH16NS60 1.02MK
2) Flash DE_LG_WH16NS60_1.00.bin

Thank you
Lucas

It works for me without the www.

that would likly work but it looks like the firmware is already old enough to not need to be flashed does it already see UHD discs but with the sleepbug?

I would like to use/try more apps as well as MakeMKV. For instance, DVDFAB needs firmware 1.0. Currently I didn't notice sleepbug anyway.
Do you think I can proceed with the following steps without break my drive?
1) Flash WH16NS60 1.02MK
2) Flash DE_LG_WH16NS60_1.00.bin
Thank you

Thanks so much to everyone that made this so easy!
I just got a Buffalo BRUHD-PU3-BK brought over to me from Japan and it's working great on 1.03 MK.
I noticed though the firmware shipped on my drive (BU14) was newer than the firmware in the MK firmware pack - I did a dump before flashing with 1.03 MK, is it useful to anyone? Would like to help if I can, and this is literally all I'm capable of

Sadly the type of dump you have is not the kind we need you would have needed to contact the developer before flashing to get a real dump your current dump is just a cal data and some version numbers
But it's not currently needed it's still flashable

Well that takes away all my capability
But massive thanks again though. It went through without any problem and I'm ripping a disc now.

Hi, Now, I am considering to purchase Buffalo BRUHD-PU3-BK.
I am wondering if the latest version of BRUHD-PU3-BK can be downgraded?

I heard that the model is end of life, so I think I should obtain one.

Don't spend the extra on it it's just a BU40N in a case
Get the archgon

Yes the Archgon is a most better drive and value for money.

Hello what do you mean with use enc

[Chatomarocoloco]

I have the Pioneer BDR-S12UHT recorder and player. Read original UHD blu-ray but could not play due to processor issue.
The problem is that I want to remove the anti copy with MakeMKV and I get the error shown in the image. Is this model compatible?
or the error is due to something else that I do not know.

a greeting.
