LG BP55EB40 - flash issue

[MFrost]

Hello, I'm a newbie here. I'd like to watch or rip a UHD Blu-ray disc on my drive. I have LG BP55EB40 svc code: EB40, manufactured: november 2016. I tried to flash the firmware, but I got stuck.

Now i got makmkv and I can’t open the drive tray:

I got the identical drive with SVC Code EB52, manufactured November 2024.

Cross-flashed it with BP60NB10 MK 1.03 firmware.

Looking at both our drive infos, the product on yours is wrong, BD-RE BP50NB40 instead of BD-RE BP55EB40.

Did you perhaps follow the SDFtool Flasher Guide to the letter and got BP50NB40 firmware in the first step instead of BP55EB40 firmware?

I would try flashing with Write and Encrypted the MK BP55EB40-NB50-1.03 firmware to see if this corrects your issue

I managed to flash it to version BD-RE BP55EB40 1.03 as you described, but unfortunately the disc tray still doesn’t open when I press the “eject” button.
