LG BU40 N Issues

[Lordsloss]

Hello everyone,

I recently purchased an Archgon Model: MD-8107-U3 and after reading the forums it appears the drive inside is an LG BU40N. I downloaded the SDF Tool Flasher in the "Downgrade Enabled Firmware V.2" and "The all you need firmware pack" I tried to use the tool and flash it to the one labeled "LG Slim BU40N" But I keep getting an error of "Check Sum is Mismatched. Drive will go to BOOT Mode. Please try again." Any ideas how to get it to work, or am I doing something wrong? Thank you in advance.

Follow the guide below and don't use that old flasher your trying to use

Hello. I tried to use the one listed in the guide and it said successful, but when I tried to copy the disk (4K The Fifth Element) it read it and errored out while trying to copy.

The error on VLC when viewing it is:

Blu-ray error:
This Blu-ray Disc needs a library for AACS decoding, and your system does not have it.
Your input can't be opened:
VLC is unable to open the MRL 'bluray:///D:\'. Check the log for details.

The error on the copy is:

Failed to save title 0 to file E:/Media Backup/The Fifth Element/Fifth Element_t00.mkv

Now it will not read the disk at all in MKV. Any ideas on what I did wrong?

Thank you in advance.

After a reset it is working fine now. Not sure why it did that, but thank you!
