Hello guys,

my drive should be ready for libre drive - but I don't find it in the firmware download.

Which firmware should I use?
Thanks for your help.

Look in the folder BU40-N-Main. Flash 1.04 MK. Then it is recommended to downgrade to 1.03 from the OLD folder.

Or just directly flash BU40N 1.03-MK from the old folder.

It's still not evident to me when you have to first flash the equivalent FW like 1.04 ->1.04 MK and when you can just skip this step and go directly to a lower version. Please enlight me.

Bu40n 1.03 to current directly to 1.03mk
Wh/16ns40 and equivalents 1.04 to current directly to 1.04mk or WH16NS60 1.02mk as recommend
And same for WH16NS60
After they added the addition downgrade checks you can only go back to those firmwares in 1 step so for BU40N that's 1.03 for WH16NS60 it's 1.02 for WH/bh16NS40 and equivalents it's 1.04
For Asus it 3.10
There is more but you get the idea

Yeah, as Billy said but the way I like to think of it is:

BU40N_1.03-MK for slim drives and WH16NS60_1.02-MK for desktop drives are magic firmware's that can be flash to from any firmware version.

Example 1: The Buffalo, Archgon and LG BU40N, regardless of current firmware version (BU13, BN13, newly encrypted 1.02 and 1.04) can all be flashed directly to BU40N_1.03-MK. If you then want to change again, such as BU10 for Buffalo, it can then be easily flashed again.

Example 2: Any desktop drive from LG (WH14NS40, WH16NS40, BH16NS55, WH16NS60 etc), regardless of current firmware version, can all be flashed directly to WH16NS60_1.02-MK, if that is what you want to use. If you want to stick the firmware from the same model, then use the MK equivalent (or 1.04-MK of same model if no equivalent).

Hallo,
I am new here and had the same problem with my new BU40N drive and ended up here.

So I flashed with SDFtool Flasher 1.3.1 the file in folder mk-firmware-pack-20200720\MK\HL-DT-ST\BU40N-N-Main\HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin - this is the 1.04 MK right?

LibreDrive Information
Status: Enabled
Drive platform: MT1959
Firmware type: Patched (microcode access re-enabled)
Firmware version: 1.04

Then I want to downgrade (like described) to HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin from the OLD folder:
But I get an error:


What do I wrong?

Did you make a restart after the first flashing? The drive usually needs a powerdown after flashing.

Also show us the error you get when flashing

Is it generally true that 1.03 MK is the best firmware for a given drive even if there's a 1.04 and a 1.05 available?

The 1st post of Ultimate UHD Drives Flashing Guide Updated 2022 includes recommended FW versions for supported drives. Newer doesn't necessarily mean better.

Hi,
thanks for your replys. I think I don't make a restart after the first flashing.

Yesterday I do a 'RECOVER Drive' in SDFtool Flasher with DE_LG_BU40N_1.00.bin.
Then after a restart I flashed the HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin -> restart
Then I flashed HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin -> restart

After that I tried to make a backup of a brand new BD, but got a lot of "Scsi error - MEDIUM ERROR:L-EC UNCORRECTABLE ERROR" ...

I thought the drive is broken after flashing, but the research for this error leads me to this thread. So i gently cleaned the disc with a soft cloth and voilà, the disk can be copied now.
