Can't read AACS VID from disc - most likely current AACS host certificate is revoked by your drive
Downloading latest HK to C:\Users\USERNAME/.MakeMKV ...
Saved AACS dump file as C:\Users\USERNAME/.MakeMKV/MKB20_v61_THE_MATRIX_2077.tgz
The volume key is unknown for this disc - video can't be decrypted
Backup failed
After my assumption, the firmware of the drive is the problem. (No signs of inssuficent power for the drive, blu-ray "The Matrix" was released 2 years ago and other users reported successful rips, I don't try to rip from an ISO/backup - https://www.makemkv.com/faq/item/11)

Here Billycar11 suggestsAll of these drives will need to be flashed to unlock UHD Reading/Ripping

Is this also true for the above mentioned 1.04? I didn't found a 'BU40N 1.03MK'-firmwareBU40N on any Firmware directly to > BU40N 1.03MK
With the SDFtool I already tried to dump the current firmware of my drive with 'READ Firmware' but only got the user data 'dump_user_HL-DT-ST_BD-RE_BU40N_1.04_212005061142_[SERIALNUMBER].tar'
Last but not least, I'm a bit confused about the encrypted firmwares here:
viewtopic.php?f=16&t=19634
I guess this affects my device but couldn't find out where to see the exact installed firmware of my drive (which is why I tried to dump it with the SDFtool, like mentioned above). I only can asume it's something like HL-DT-ST-BD-RE_BU40N-XXXXXXX-212005061142Newer OEM Firmwares and encrypted:
New Encrypted firmware
List of Know Encrypted firmware (so far, any firmware with date in 2020 is encrypted)
...
HL-DT-ST-BD-RE_BU40N-1.04-N000500-212005061142.bin
...
LG 1.04+ / BU40N 1.03 / Asus 3.10+ and similar
...
But there is the, again, above mentioned 'HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin', so I can use this?...and there is no MK version of the same firmware/drive model or higher number...
My questions would be, did I miss anything? And if not, can I just flash it with "mk-firmware-pack-20200720 \ MK \ HL-DT-ST\BU40N-N-Main \ HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin" and the SDFtool? Is the 'DE'-firmware (DE_LG_BU40N_1.00.bin) any use to me?
I hope my thoughts are not too confuesd.
In advance I would like to thank you for every bit of advice.
