Ultimate UHD Drives Flashing Guide Updated 2026

[Billycar11]

Hi folks,
Apologies if this is the wrong place to ask... I'm new to the forum and Makemkv.
I have the following drive, which from what I've read here I think I should be able to flash with revised firmware to enable Libredrive. Where I'm unsure is which fireware I should be using so I would appreciate some pointers as you where to look.

Drive Information
OS device name: F:
Manufacturer: HL-DT-ST
Product: BD-RE BU50N
Revision: GE03
Serial number:
Firmware date: 2119-04-23 16:48
Bus encryption flags: 1F
Highest AACS version: 68

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

Can I also check that I should use the SDFtool flasher and lastly do I just flash the new firmware or should I be backing up the existing drive forward first.

Sorry for all the probably obvious newbie questions and thanks in advance for your help.
Mike

Treat it as a bu40n
Backups are not needed

Or email me or Marty for an automated flasher
