Hello,

I purchased a Verbatim Ultra HD 4K Blu-ray player with the model code KIAB and serial number 43888. When I launch MakeMkv (v1.18.3 [win(x64-release]]), it gives me the following information:

Drive Information
OS device name: F:
Current profile: BD-ROM
Manufacturer: HL-DT-ST
Product: BD-RE BU40N
Revision: 1.05
Serial number: ***
Firmware date: 2124-04-23 13:47
Bus encryption flags: 17
Highest AACS version: 76

LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959

Should I flash it?
How can I flash it without causing an irreversible error ?

For your information, I put a Blu-ray in the drive, and after playing it with MakeMkv, I get the following error:

Code: Select all

Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - KEY NOT PRESENT' occurred while issuing SCSI command A40..002000800 to device 'SPTI:\Device\CdRom0'
Error 'Scsi error - ILLEGAL REQUEST:COPY PROTECTION KEY EXCHANGE FAILURE - KEY NOT ESTABLISHED' occurred while issuing SCSI command AD010..080002400 to device 'SPTI:\Device\CdRom0'
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\ERIC/.MakeMKV/MKB20_v76_Elvis_E891.tgz
LibreDrive compatible drive is required to open this disc - video can't be decrypted.
Failed to open disc

Thank you for your help

You need to flash it to BU40N 1.03-MK to enable libredrive. Just do it. It's extremely easy.

Thank you.
Is there a risk that I could render the player unusable if it malfunctions?

If so, can I revert to version 1.05?

Is this procedure on this site suitable?
https://github.com/nxyzo/Flashing-Verba ... -to-1.03MK

Can I use the file it provides?

Thank you.

I'm continuing my search for how to flash my player. The forum is very comprehensive, but I'm having trouble finding what I need.

I'm looking for the file I need to flash my player.

But I can't find it anywhere on the forum.

If I understand correctly, then I just need to do it like this.

- Close MakeMKV
- Open Command Prompt as Administrator
Navigate to the MakeMKV installation directory:

cd "C:\Program Files (x86)\MakeMKV"

Execute the firmware flashing command:

makemkvcon64.exe f --all-yes -d X: rawflash enc -i "PATH_TO_FIRMWARE_FILE"

(Replace X: with your optical drive letter and PATH_TO_FIRMWARE_FILE with the full path to the .bin file)

Please tell me if this is correct and correct me if I'm wrong.

As a reminder, here's the information provided by MakeMKV. .
