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.sukaimakyuri wrote: ↑Wed Dec 03, 2025 1:41 pmHi, 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.

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.
