Hello everyone,
​I am trying to flash my drive to enable UHD reading (LibreDrive), but I cannot find the correct firmware file for my specific unit in any of the Custom Firmware Packs I have checked.
​My drive details are:
​Model: HL-DT-ST BD-RE BU40N
​Current Firmware: 1.05
​Could someone please share or point me to the exact .bin file I need to use with SDFtool Flasher?
​Thank you in advance!

Assuming the manufacturing date is 2016 or later, and the drive platform is MT1959 (which it should be), flash DE_LG_BU40N_1.03_MK.bin from MartyMcNuts' All You Need Firmware Pack. Then if you want DVDFab compatibility on Windows (or you have issues with Linux compatibility), flash DE_LG_BU40N_1.00.bin

EDIT : Also, that's a regular WRITE for this one with the default encryption settings (there will likely be encryption for the flash to DE_LG_BU40N_1.03_MK.bin, and there will be no encryption for the second flash to DE_LG_BU40N_1.00.bin if you choose to do it). No bootloader flash, no RECOVER.

The problem is that I cannot find it anywhere. Could you provide the exact path or a direct link? Thank you.
