Possible DOA drive?

[jedix]

I recently purchased an LG WP50NB40 with SVC Code NB52 Rom Version 1.03

I run Linux and haven't flashed anything.

Starting makemkv (which has beta registration valid for 2 more days) never stops seeking on a bluray or dvds.

Drive Information
OS device name: /dev/sr0
Manufacturer: HL-DT-ST
Product: BD-RE WP50NB40
Revision: 1.03
Serial number: <redacted>
Firmware date: 2121-07-08 16:09
Bus encryption flags: 17

LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959

Disc Information
Disc is being loaded

I'm not entirely sure if this is valid, but I also cannot dump the firmware with:

Code: Select all

makemkvcon f -d /dev/sr0 dump -o ./

strace shows that the command stops at write(1, "\n", 1) and the process consumes 100% of one of my CPUs.

I was planning to:
1. flash /LG slim BP50NB40-NB50/HL-DT-ST-BD-RE_BP50NB40-NB50-1.03-NM00800-212005070917.bin
2. flash (recover somehow in linux?) LG slim BU40N/HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin

but wanted to make a backup first. Is this drive DOA or will none of this work before I flash?

The drive has a strange usb cord with two plugs, so I tired plugging one in, two in, one into a powered hub, two into my pc. The spin up and reading sound fine, but the drive never seems to return.

It was the latest 1.17.8 linux version.

vlc was able to use the 1.17.8 library to open discs, downgrading to 1.17.5 worked and I was able to flash the drive.
