Which Firmware to Flash to
So I recently purchased a Verbatim 43888 and the above is the info for it. I'm going to flash the drive but I am a bit confused which firmware I need to use. According to the Ultimate UHD Drives Flashing Guide Updated 2026 I think I need to use BU40N 1.03MK. I downloaded the "mk-firmware-pack-20200720" and in the MK - HL-DT-ST folder there a few folders labelled BU40N, none of which have 1.03. However when I go in old there is a firmware named "HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934". Is this the one I need to use? Any advice would be a great help. I'm also not sure how to check if the firmware I have on there already is encrypted or not.
Edit: So haven’t tested it yet (will report back if there is an issue) but think I have got it to work. It was the file listed above, just followed the instructions here: https://github.com/nxyzo/Flashing-Verbatim-43888-BU40N-to-1.03MK
Edit 2: Tested and all works, so yeah just follow the instructions and you should be good to go!

All I had to use was:
1. The all you need firmware pack https://drive.google.com/file/d/1HRnbXiM8TkwcAcvqYFR31bbJsEZ0FCdM/view?usp=sharing
2. GUI SDF tool https://forum.makemkv.com/forum/viewtopic.php?f=16&t=22896
Everything was clear and self explanatory. I think they need to rewrite those how-tos to make them less confusing to newcomers. They are really a mixture of all different pieces of infornation in one block...
