We have extensively tested the BP55EB40 with both 1.02MK and 1.00MK firmware versions.lmwardx wrote: ↑Tue Mar 17, 2026 3:45 pmSo 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!Coopervid wrote: ↑Tue Mar 17, 2026 1:37 pmYes, 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.lmwardx wrote: ↑Tue Mar 17, 2026 11:48 am
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!

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!
Firmware 1.00MK is clearly the best option if you are using the drive solely with MakeMKV. If you require broader compatibility (e.g. DVDFab support), then the BU40N with 1.00DE firmware is the better choice.
In our testing, 1.02MK frequently failed on discs where 1.00MK succeeded first time.
We would agree with martymcnuts, newer is not always better.
