I am also having trouble with my BP50NB40 SVC NB52 (manufactured 1/2026). I cannot seem to locate the BP50NB40 (NB52) 1.03-MK bin file. Can someone point me in the direction of where to find this? I only see the HL-DT-ST-BD-RE_BP50NB40-NB50-1.03-NM00800-212005070917.bin located in the "The all you need firmware pack". Full disclosure - I downloaded this to my drive on accident already.

I also downloaded the "Hybrid_Firmware_for_BP50NB40_to_BP60NB10" pack but those were not successful either. I need the BP50NB40 (NB52) 1.03-MK file still in order to proceed with flashing, I think? Once I have that, I see I need to crossflash by recovering the drive first, as previously stated by MartyMcNuts.

Any and all help welcome! I'm a bit of a newbie, so any and all instruction/feedback welcome

Thank you!

No, you want the BP50NB40 NB50 1.03 MK firmware, not NB52.

Everything you need is in my all you need firmware pack along with the gif showing you what to do in the first post of the SDFtool Flasher thread.

Thank you, Marty! Quick question - the only bin file I'm seeing in the firmware pack is the HL-DT-ST-BD-RE_BP50NB40-NB50-1.03-NM00800-212005070917.bin file - it doesn't really say 1.03 MK. Is this the correct one? If so, I will try again, but I did try this in the SDFtool and I'm still getting that my drive is a BP50NB50, even after applying the BP60NB10 file.

Appreciate the response!

Yes, that is the MK firmware. First flash this. Make sure that it is then showing this in Makemkv info. The start the recovery process as shown in the gif.

So I definitely didn't scroll down far enough to download your specific All You Need Firmware Pack... I just had the one that was posted in the main topic of this thread. I downloaded yours, followed your instructions/GIF and everything worked like a charm!

To claim one more moment of your expertise - I downloaded the BP60NB10 1.00 MK firmware to my drive, but there is a 1.02 MK bin available. Is it better to upgrade to the 1.02 or leave as 1.00? My other disc drive (same model, but SVC is the NB50) is 1.02, so wasn't sure if it was recommended I flash to latest version.

Appreciate your time!

1.02 is recommended but probably no big difference. If you want to use other ripping software like DVDFab you must flash BU40N 1.00 from the All you need package.

The last time I flashed a drive it was 7 years ago and I believe I used a LG firmware flashing program if my memory serves me right. This drive cost nearly $300 and don't want to brick it.

if someone can please post a link or tell me which firmware I should download and which way of flashing I should use?

The SDFtool Flasher GUI is simply a front end for the CLI. This is simply to make it easier for those not familiar with using CLI.

Also, it is recommended to use WH16NS60 firmware for your drive, not WH16NS40 firmware. This is because the NS60 firmware removes the UHD disc sleep bug and also reads faster.

Use WH16NS60 1.02-MK if you only use MakeMKV or Xreveal for UHD ripping or WH16NS60 1.00 if you use other UHD ripping software. All the firmware you need is in my firmware pack.

Went through the process of updating the firmware to allow UHD movies. After using the GUI to update the firmware, I was able to save the 1st LOTR movie, but now it won't save anything. Have reflashed, even via the MakeMVK built in program following the video guide (have dual boot on my main computer).
Linked to below is the drive I purchased, the 2nd drive I bought for the case to do the flashing (read about the issue with archgon cases). And a screenshot of MakeMVK showing my drive information and the error I'm getting.
One thing that's odd, is the 1st movie worked while keeping the drive in the 2nd case. But after the 1st movie, it'll randomly disconnect after clicking on the drive icon to load the movie info. When I use the original case, it won't randomly disconnect, but it does what's shown in the screenshot.

If this is a lost cause, I'm ok buying a new drive (please point me to a good one for UHD). But certainly would prefer not to if I can avoid it (they are pricey. lol)
Thank you!!!

you have a power issue try a higher powered usb port or get a powered usb hub

still having an error. switched to a desktop so there is better power available. Got it so it doesn't randomly disconnect. But will still fail. Screenshot below. There is an error that comes up about "downloading latest HK disabled or failed". Not sure if that is relevant? 1st time it tried to download that, it just sat there a while and failed.
