LibreDrive firmware for HL-DT-ST BD-RE BU40N

[mdhankins1]

Hello. I am a little confused about which LibreDrive firmware to pick for this drive. Any help? Using the mk-firmware-pack-20200720.

HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin (BU40N-N-Main)

HL-DT-ST-BD-RE_BU40N-U100-3M01801-211910161036.bin (BU40N-U-Tier2-Non-UHD)

When I view my device in SDFtool Flasher, it shows HL-DT-ST_BD-RE_BU40N_U101_212012011720_MO6L9191353

Thanks

The Ultimate UHD Drives Flashing Guide says BU40N on any Firmware directly to > BU40N 1.03MK

When I try the BU40N 1.03MK firmware I get an error message.

Command produced error code 0xff05c103

(nevermind, I tried the following morning and the flash worked)

Acutally I am a bit puzzled, too.

I tried to flash my drive, and it looks promising in the first moment:

Code: Select all

PS C:\Program Files (x86)\MakeMKV> .\makemkvcon64.exe f --all-yes -d  E: rawflash -i HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin

But after I restarted the pc and open makeMKV it still states this information:

Also - I though it might be some drive caching issue - I just gave it a shot. But without luck:

Can't read AACS VID from disc - most likely current AACS host certificate is revoked by your drive
Saved AACS dump file as C:\Users\(...)\(...).tar.gz
LibreDrive compatible drive is required to open this disc - video can't be decrypted.

Thanks in advance for any help.

EDIT
I also tried the sdftool_flasher with the FW Versions 1.00 and 1.03 (as recommended)

HL-DT-ST-BD-RE_BU40N_1.02_212012011716_MO3L91F0715.bin is listed as an encrypted FW in the guide. Either add enc to the command line, or make sure 'Encrypted FW' (?) is a green check in the GUI tool.
