I had made this post into its own thread, but apparently new accounts go into moderator approval, and the one mod that is still active was last online 2 days ago...so...ima try posting it here and see if anyone sees it.
Sanity check request for BP50NB40
Recently bought a BP50NB40. It's NB52 and was built in May of 2025. I am on linux (arch). I use the linux version of makemkv 1.18.1. I'd really prefer not to have to create a windows VM if I can avoid it.
From browsing guides and threads, it looks like what I need to do to get UHD ripping working is:
Found 1 drives(s)
00: dev_21:1, /dev/sr0, /dev/sr0
HL-DT-ST_BD-RE_BP50NB40_1.03_212107081603_<serial_number_of_drive>
So my later commands would go to /dev/sr0, right? Because I have no idea what dev_21 is. I assume that slot is specific to something for Mac.
Question 2:
Everything I can find on these forums indicates that the right way to flash this drive is a 2-flash process. But the UHD Sept 2025 guide (viewtopic.php?t=19634) makes it look like a 4-step process of:
Original Firmware, starting state
Load DE_LG_BP50NB40-NB50_1.03_MK.bin with encryption mode
Load DE_LG_BP50NB40-NB50_1.03_MK.bin again, but this time with 'full' mode instead of 'enc' mode
Load DE_LG_BP60NB10_1.00_MK_HBD.bin
Load DE_LG_BP60NB10_1.02-MK.bin
When I read
BP50NB40 to > BP50NB40-NB50-1.03MK then to > BP60NB10 1.02MK or 1.00MK
NB52 to > BP50NB40-NB50-1.03MK with enc > BP50NB40-NB50-1.03MK with bootloader/full flash > BP60NB10 1.00_HBD from Marty download/file.php?id=2143
if using command line add "full" after rawflash
BP60NB10 on any Firmware directly to > BP60NB10 1.02MK
I get the 4-flash process above. Which goes against literally everything I've read, so I assumed I was wrong. Am I?
Thanks for the guides/firmwares/etc. Some of the movies I wanted to buy are only sold in UHD. And they didn't have blu-rays inside. So...literally the only way I can use my purchase is to figure this out.
Yes, you are incorrect. All you need to follow is:
NB52 to > BP50NB40-NB50-1.03MK with enc > BP50NB40-NB50-1.03MK with bootloader/full flash > BP60NB10 1.00_HBD from Marty download/file.php?id=2143
if using command line add "full" after rawflash
This part: BP60NB10 on any Firmware directly to > BP60NB10 1.02MK is if you have a BP60NB10 drive to begin with.
Cheers

The latest version with `makemkvcon f` working for me is `1.17.7`
If that information is already present in the first page of this thread, it would safe me a looooooooooooooot of time.
I recommend changing the first page guidance to add this information in the How To Flash Videos and commands:

You don't have to use 'makemkvcon f', you can replace it with 'sdftool'.

I did a search, but nothing came back for this issue - so I apologize if this has already been addressed previously.
I have a Mac Mini M2 Pro running MacOS Sequoia 15.6.1 with the LG BP60NB10 drive. Haven't had any issues with DVD or regular Blu-ray discs, but UHD Blu-ray discs aren't working. Did a search and came across this in the forum stating the drive needs to be flashed for UHD discs to work.
My LG drive has Svc code NB12, manufactured in November 2023. I attempted to flash following the instructions, but I received an error that said "There is a disc in the drive, please remove it and try again." I removed the disc and tried again. With no disc in the drive I receive an error that says "Drive "/dev/rdisk6" not found."
So basically - I put any disc in and it tells me to remove the disc, I remove the disc and it can't find the drive.
It's been a hot minute since I've flashed anything like this, so I may be a little rusty. Any help is greatly appreciated.

Can you copy and paste the command you're using to flash on your Mac? On a Mac I'd be surprised if the drive identifier from step 6 returned /dev/rdisk6. I would expect it to be /IODBServices/###.

I figured out what the issue was! The LG drive was plugged in to a USB hub, which I had forgotten because it had been connected for over a year and a half. The USB hub was preventing the correct identifier from showing. Everything started working properly as soon as I connected the drive directly to my Mac Mini, and I was then able to flash it. After I flashed it I moved it back over to the USB hub and UHD discs are working now.
Thanks for your input!

I just want to report that I successfully flashed a Pioneer BDR-212 in the ICY BOX IB-525-U3 USB enclosure powered by the 12V 3A power supply that came with it. Flashing on Windows is super simple and @Billycar11 is helpful, too.
Perhaps the model number of this case could be mentioned in the original post. BTW, the enclosure is deep enough for Pioneer drives so no modification to the case is required. Besides, it seems to be widely available in Europe.
Thank you to everyone involved with this flashing effort. This is an amazing thread!
One request: Please provide a filehash of the zip files so that we can trust them upon download. Ideally the .exe would also be digitally signed but at the very least having a SHA256 of the zip files will help. Downloading anything from the Internet should give everyone pause unless there is a signature (embedded, sidecar, signed manifest, or at least a filehash).
Hello everyone, I have the following drive and it works perfectly with dvds and blu-rays, but I recently got a couple of UHD titles and wanted to see if it is possible to make this one UHD capable? Thanks in advance!
