Hi everyone,

I’m hoping someone can help me figure out why my drive still won’t read UHD Blu-ray discs after flashing.

The drive works perfectly with standard Blu-ray discs. I can rip regular Blu-rays in MakeMKV without any issues. The only problem is with 4K UHD discs.

Drive information:

* Manufacturer: HP
* Model: HLDS BU40N
* Firmware Revision: BW42
* Platform: MT1959

MakeMKV: v1.18.4

I purchased the drive in this enclosure:
JOYIN-BURN 9.5mm Tray-Loading USB Blu-ray Drive (Amazon ASIN: B0CS3MY2DG).

I used the latest SDFTool Flasher and the “All You Need Firmware Pack.” I manually selected DE_LG_BU40N_1.03_MK.bin, and the flash completed successfully without any errors.

However, MakeMKV still reports:
LibreDrive Information
Status: Possible (with patched firmware)
Firmware support: No
Firmware type: Original (patched version available)
Firmware version: 0.BW42P

When I insert a 4K UHD disc, I receive the following error:
LibreDrive compatible drive is required to open this disc.

Since standard Blu-rays work perfectly, I’m wondering if my HP BW42 drive requires a different firmware or cross-flash procedure, or if there’s something I should verify before attempting to flash it again.

I’d appreciate any advice. Thanks!

New to this side of things, when you say my case is likely junk do you mean the literal case holding the drive or case as in my scenario. I don’t mind trying to remove the case of it will make it function correctly as it works with normal blue rays perfect just not 4k UHD.

Yes, remove the drive from the casing.
