Ultimate UHD Drives Flashing Guide Updated 2025

[Billycar11]

I'm so confused by the pioneer drives. I want to buy one to see if it helps with some disks that are giving me io errors. However there are multiple conflicting statements, even in this main thread. What is the current status with Pioneer drives? Are the green highlights (pioneer works, w/ drive list) accurate, or the yellow highlights accurate / must buy from re-seller?

the yellow you need one from a seller unless you fine one with fw before 12/22

So I'm pretty sure my WP50NB40 is a paperweight but I just wanted to check if anyone had any ideas on if this can be fixed.
I flashed the MK 1.02 build which it showed on MakeMKV and then I proceeded to do the cross flash to BU40N. In a moment of monumentally poor judgement I unplugged the drive when I mistakenly thought it was finished flashing. Now the drive reports its Revision as BOOT does not respond to the button press and the flasher GUI reports it is not an MT1959 and makemkv flasher just sits there.

I tried creating the bootable USB for the DOS flasher but it does not boot so I have not been able to try that yet.

flash it with the official LG updater sometimes they can unbrick it

No dice. It also recognizes it and marks the rev as BOOT but I immediately get a WRITE DRAM NG 05/26/03. Thank you!

Is it a problem if the disc says have never been played in a 4k player before trying to do them?
As I stated they show up but then once they spin down it says no disc. But I can do other 4K movies like labyrinth, Jumanji and Deadpool versus wolverine.

And I have zero issues with any Blu-ray or DVD?

No. I rip 4K movies all the time. I don't even own a 4K disc player.

Same. I have never owned a UHD player.

Hello, I am very new at this and am a little confused on what drive to purchase.
I am currently looking at purchasing a drive but it looks like they are all sold out on amazon.

Any tips on which one to buy that is currently in stock?

Thanks!
