Hello everyone,

I just bought a LG BU40N slim drive on Amazon that I put in an Icy Box external enclosure and connected it via USB-C to a MacBook Pro running Mac OS Ventura (13.6.9)

I followed the ultimate flashing guide and unfortunately the drive stays on its original firmware, even if the flashing procedure ends successfully

Here is what I did:

Code: Select all

./makemkvcon f -l                                                                                                                  
Found 1 drives(s)
00: /IOBDServices/BA1A4879
  HL-DT-ST_BD-RE_BU40N_1.04_212005061142_MOFO43B5246

Code: Select all

./makemkvcon f -d '/IOBDServices/BA1A4879' -f /tmp/sdf.bin rawflash main -i /tmp/HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin

When I open MakeMKV 1.17.7, here is the info about my drive:

Thank you very much! This helped me a lot as well.

For my understanding: When I used the MK firmware, do I need to flash any other non-encrypted firmware on top of it?
