Please help with BU40N "you cannot flash your drive to this firmware file directly" error

[Theozefrench]

Hi all,
Long time MakeMKV paid user, I want to rip 4K movies and after spending a few days in this forum I bought a BU40N slim external drive.
This is MakeMKV drive info :

Revision: 1.01

Bus encryption flags: 1F
Highest AACS version: 71

LibreDrive Information
Status: Possible (with patched firmware)
Drive platform: MT1959

This post : viewtopic.php?f=19&t=22653 says the fimware to use is the BU40N-N-Main, but wen I try to flash it I get the "you cannot flash your drive to this firmware file directly" error.

I feel I'm almost there, probably some intermediate firmware to flash, but can't fint the missing bit of information. Can you point me to what I am missing ?

Thanks for your time !

Thanks for your time !

Also, the SDFtool Flasher has been updated. You should be able to flash the BU40N with firmware DE_LG_BU40N_1.00 firmware.
