Hi, I got the following BU50N drive and try to flash the firmware to enable LibreDrive. I searched the forum with 'BU50N' and went through 13 pages of search result. It seems that I should use "mk-firmware-pack-20200720\MK\HL-DT-ST\BU50N\HL-DT-ST-BD-RE_BU50N-1.00-NM00100-211711211006.bin" from this page: viewtopic.php?f=19&t=19113. Am I correct? Thanks a lot!

firmware for BU50N
Re: firmware for BU50N
You can use it or flash to BU40N 1.03MK.
The BU40N and the BU50N is the same hardware. The different model names related to different distribution channels.

Re: firmware for BU50N
Thanks a lot for your reply. I used the "All You Need Firmware Pack (MartyMcNuts)\Slim External Drives\DE_LG_BU40N_1.03_MK.bin" and it works! But just curious to know whether there will be any difference between this "DE_LG_BU40N_1.03_MK.bin" and "mk-firmware-pack-20200720\MK\HL-DT-ST\BU50N\HL-DT-ST-BD-RE_BU50N-1.00-NM00100-211711211006.bin"? Thanks again!
Re: firmware for BU50N
The BU40N / BU50N 1.00 is the original LG firmware and is nativly 4K friendly.
Advantage: You can use other tools like DVDFab also.
Disadvantage (in my opinion): The 1.03MK has less problems with difficult discs.
