MKB20_v77_Mission-_Impossible_Dead_Reckoning_Part_One_F473.tgz.

I tried again using the latest keydb.cfg, but I’m still getting the following error message:
The volume key is unknown for this disc - video can't be decrypted
DEBUG: Code 0 at K/7I6&O",`|u5 8d:213132721
DEBUG: Code 0 at K/7I6&O",`|u5 8d:213131341
Failed to open disc

Here is the link to the shared file: https://drive.google.com/file/d/1Keiciq ... drive_link
I’d appreciate it if you could take a look and let me know if there’s anything else I can try.

Best regards,
MrPenguin

Could you also provide the (zipped) AACS/MKB_RO.inf file from your physical UHD disk please? The copy of MKB_RO.inf inside your TGZ dump file has been truncated to only 56 bytes, which makes it unusable to anyone except MakeMKV itself :(.

This is a Google Drive link where the disc’s mkb_ro.inf file has been uploaded.

Thanks for posting the full MKB_RO.inf file watz2z, your disc has been added to the public keydb.

If you haven't previously configured MakeMKV to utilise the public keydb you can follow my instructions here or use SamuriHL's utility for Windows (Link)
Public KeyDB Disc Submissions
  • LG/Buffalo/Asus drives only (Pioneer drives are not supported)
  • Please use file hosts, not forum attachments
  • If your disc dump is under 3MB, you need to manually include the MKB_RO.inf file from the AACS folder
