That worked, thank you!

My bad.. I thought you meant that I tried the command without the enc param when you said no enc.. should've read the guide more carefully.

Here is the complete command that I ran:
LD_LIBRARY_PATH=../lib ./makemkvcon f -d /dev/sr0 -f sdf.bin rawflash enc -i HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin

Has anyone manage to flash a BU40N with the GC02 firmware? Every time that I try, it never commits.
Every flash attempt with 1.03MK reports full success via makemkvcon rawflash/enc on Linux. After every cold boot, makemkvcon -l still reports GC02, unchanged.
