So my kid got his biggest wish fulfilled for his 13th birthday. The Verbatim 43888 (LG inside).
He now managed to brick it.
Yesterday we used the SDFtool flasher and successfully flashed it to DE_LG_BU40N_1.03_MK.
It could now rip 4K and everything was wonderful.
While I was at work (he’s on vacation) he went down a rabbit hole of wondering why it was slightly slower for HD discs than UHD. I told him not to worry about it and just enjoy ripping.
He instead decided that he could probably fix that by downloading and flashing it with some ancient tool from LG website. I assume he didn’t read the instructions and he totally neglected several warnings in the read me. After it had been stuck for an hour at 48% I forced it to stop. The flashing tool it self said it would take 2 minutes.
Now the drive is visible in windows device manager, but not doing anything. Eject doesn’t work.
The SDFtool can see the drive but it’s no longer MT1959.
Any advice? Apart from that he clearly learned a 150$ lesson and wasted his birthday present by thinking he could walk on water.

Manufacturer: HL-DT-ST

Revision: BOOT
Edit: he’s using a windows machine, but I have a Mac if that gives us other options

Thanks, Coopervid.
We found this thread viewtopic.php?f=16&t=40486 where someone suggested a similar tool from dell: https://www.dell.com/support/home/pl-pl ... erid=hn7y6
While I didn't check the checksum etc from that tool it looked identical to the LG flasher tool. So I can't tell if the LG tool would do the same.
Nevertheless. The dell tool worked. We ran it as admin and in windows 8 compability mode and it quickly got passed the 48% and MT1959 got enabled again.
Finally flashing with SDFtool and everyone is happy. I bet it will take a while before he tries to flash the firmware of something else
