Ultimate UHD Drives Flashing Guide Updated 2026

[trooperdadon87]

I'm new to the forum. I've been using Makemkv primarily for my Blu-rays to back them up to an external hard drive. It's always worked great so far.

However, I want to switch to 4k UHD soon and so my question is:

Is this generally possible with my BR drive "Techpulse 120" BD-XL M-Disc and 4K UHD is written on the front?

Do I have to flash this first? How do I go about this? Unfortunately, my English skills are a bit poor.

Thank you for your help and I hope I'm in the right post.

Greetings, trooper

Post your MakeMKV drive & Libredrive info.

Yes, it has to be flashed to enable libredrive as it is a requirement for UHD readability.

It's easy to do. Just follow the guide. Your drive is a LG BU40N. Flash it to BU40N 1.03-MK and you're all set.

I got the LG WH16NS40 Flashed with WH16NS60 Firmware v1.02, very simple yet it performs at it should, Have done only few rips but I will report back if I find any issues with it, but so far so good.

Bought an LG BH16NS40, FW 1.05, SVC CODE NS51, manufacturing date 2024 October

Now I cannot find this drive in post#1 exactly but reading viewtopic.php?t=25901
I see user had success with flashing HL-DT-ST-BD-RE_BH16NS40-NS50-1.03-NM00000-211711201943.bin

1 - can I somehow backup the current FW which I can restore in case of issues? or restore is not fully possible?
2 - since that success story is from 2022 perhaps my current 1.05 is a different 1.05, also my drive is a different BH16NS40, possible?
3 - thank you

Show your MakeMKV drive information.
But I think you can flash directly to WH16NS60 1.02MK.

Edit:
Sorry I've read your model wrong. Of course is the BH16NS40 with NS51 flashable.

You don't need a firmware backup. With the original LG firmware auto updater you can get your drive back to 1.05.

Should I flash it to 3.10 MK?
