Failed firmware flash LG BP55EB40 SVC EB40

[Troubadour]

Hello!

I tried to flash this drive:

LG Slim Portable Blu-ray/DVD Writer
Model: BP55EB40
SVC Code: EB40
(Nov. 2016)

as described here:

viewtopic.php?p=130958#p130958

But something went wrong and now the drive no longer works: The drive is still recognised and can be flashed, but when the eject button is pressed, only the LED lights up and the drawer no longer opens.

I have removed the drive (it is labelled with "Model: BU20N") from the case and installed it in a notebook, with the same effect.

Is there any other way to get the drive working again? It does not have to be UHD friendly...

I would be very happy if someone here could help me!

Yeah needed to be nb50/eb50 to flash it should have read the guide.
You can try flashing it back to an old NB 40 firmware with the recovery option in sdfgui

Thank you for your answer.

I found the solution here viewtopic.php?p=129930#p129930

I did a recovery flash from the firmware

DE_LG_BP50NB40-NB50_1.03_MK.bin
to the
BP50NB40-NB40-1.00-Clean.bin

Now it works again and it's a LibreDrive too.
