Hi, my newly purchased a Verbatim Slimline drive currently cant rip certain DVDs and 4k Blurrays. A few do work, but I mostly use this specifc drives for 4k Blurrays and none of them worked.
Now, first of all, I could not find out if this drive is encrypted, and neither certain if the flashing shown here will work to enable LibreDrive. I downloaded the "All you need firmware pack" and the SDF Tool flasher already. Within the Firmware pack is a LG Slim BU40N, I assume that is the firmware required for this specifc drive. Am I missing something or coud I get started flashing using the flasher with the LG Slim Bu40N Firmware to enable LibreDrive?
Furthermore, from the list of encryped firmware I am uncertain if this drive is in fact coming with an encrypted firmware because I could not find the exact same one in the list but similar enough.
Drive Information
OS device name: D:
Manufacturer: HL-DT-ST
Product: BD-RE BU40N
Revision: 1.05
Serial number: MO4P33E2415
Firmware date: 2124-04-23 13:47
Bus encryption flags: 17
Highest AACS version: 82
LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959
No disc inserted
Excuse me for the silly questions. I would prefer not to instantly brick my newly purchased drive, given I already own an other drive which is not for 4k Blurrays and just the normal resolution.
As the drive is manufactured in 2024 the firmware is encrypted. SDFTool flasher will set this oprion automatically and you should flash BU40N 1.03 as recommended firmware. If you are using other ripping software besides Makemkv you should flash 1.00. The files are in the "all you need firmware pack" in the SDFTool post by Marty.
First time trying this with a UHD drive (my old bluray still works like a champ)
The PC looks like it recognises discs ok, but in MakeMKV it doesn't look right.
It sees the drive as:

The SDFTool pops up an error when I tried to backup the fimware:
"The drive you have selected does not have the correct drive platform (MT 1959) and cannot be flashed"

Would I be right in thinking the problem is the cable I'm got for it?
It's SATA > USB

I have a BP60NB10 drive that I flashed and it was working great. Drive stated having issues reading discs, so LG said I can send it back to get it replaced since it is under warranty. But in order to do that I need to flash the original firmware back on it. Is that something I can do? If so, how? I was looking at the recover option, but when it comes to selecting the correct new firmware, I didn't know what I would choose.
All working as hoped. However, if you try to flash the drive while the disk drive tray is ejected SDFTool throws an error with an error number. Would it be possible to check the status of the drive tray and throw a more human readable error if it's currently out?

Returned the drive and replaced it with a Verbatim 43888 ( https://www.amazon.co.uk/dp/B07MTP9VKX )
Much much nicer drive and comes with the cables and adapter options.
Easy firmware backup then install of DE_LG_BU40N_1.03_MK.bin
Currently testing with our Apollo11 UHD disk and it's doing its thing.
Thanks @Billycar11 for the nudge in the right direction

Um, no. It is just a GUI for the sdftool CLI so whatever error it spits out is it.

I downloaded the sdftool flasher for my PC to try and use it for my Blu-Ray player, but when I open the tool, the box opens like this and I can't resize it to use it I have a Windows 11 PC.

NOTE: If the GUI looks a bit deformed (happens on a 4k monitor), you can right click the exe and select properties. In the compatibility tab, click "Change high DPI settings" then under "High DPI scaling override" tick the box and select "System (Enhanced)" in the dropbox.

Thank you Marty, I finally received my UHD blu rays from storage and the Buffalo flashed drive works a treat - faster than expected. I really do appreciate all the work you do! Be lucky.

Apologies if this is in the wrong thread…newbie post but not new to the amazing makemkv software.
Bought the Buffalo BRUHD-PU3-BK. Read through the threads and wasn’t sure if it was BUN-40 flash process. I’m confused what to use, not done this before.
Thanks all.

Yes, it's a BU40N. You can flash it to BU40N 1.03-MK.
Thank you Marty, I really appreciate your reply.
I’ll use the LG BU40N 1.03mk. Is it simply ‘select drive’ “select write’ open this firmware from the pack and start?
