The guide in the first post is great. I deeply appreciate the effort and work BillyCar, MartyMyNuts, et all put in. Really excellent. But it's also very generalized. So here is what I did, using their work, to get my specific drive working. The hope is just to help people with the same setup have more specific directions. (Or maybe just for me if I have to do it again ever)
The drive is a
WP50NB40 "LG Super Multi Blue Slim Portable", service code NB52. Flashing from a
Mac on Tahoe 26.2.
This zip file has all required files. (MakeMkv 17.7, the two firmwares, sdf.bin). Copied out of the first post, just the ones you need, in one place. -

1. Install the old (17.7) version of MakeMkv. Try to open it, get the security warning, bypass the warning in "System Settings -> Privacy & Security -> Open Anyway".
1.b. It won't actually run after that. Just crashes when you try. Doesn't matter. We're just going to be using a utility installed with it, from the command line. When we're finished with the flashing, we can remove this old version and use the current version.
2. Open the terminal. Change your working directory to /Applications/MakeMKV.app/Contents/MacOS/ ( "cd /Applications/MakeMKV.app/Contents/MacOS/" )
3. Run the command "./makemkvcon f -l", copy the part that says "/IOBDServices/XXXXXXXX" to notepad.
4. Copy the two firmwares and sdf.bin (from attached zip) to /tmp ( "cp 'path to where you extracted them' /tmp" )
5. Flash the first firmware, "HL-DT-ST-BD-RE_BP50NB40-NB50-1.03-NM00800-212005070917.bin". The current firmware is encrypted, so the command is the second one in the guide.
5.b. It's easier to write the command in notepad, and copy it into the terminal. So copy this, replace the XXXXXXX with the numbers you copied earlier, and then paste into the terminal.
Code: Select all
./makemkvcon f -d '/IOBDServices/XXXXXXXX' -f /tmp/sdf.bin rawflash enc -i /tmp/HL-DT-ST-BD-RE_BP50NB40-NB50-1.03-NM00800-212005070917.bin
Unplug the drive, wait 5 seconds, plug it back in.
7. Run "./makemkvcon f -l" again, if the numbers changed, copy them into notepad again.
8. Flash the second firmware, "DE_LG_BP60NB10_1.00_MK_HBD.bin". It's no longer encrypted, so use the first command from the guide.
8.b. Do the whole copy it into notepad, paste into the terminal dance again.
Code: Select all
./makemkvcon f -d /IOBDServices/XXXXXXXX -f /tmp/sdf.bin rawflash main -i /tmp/DE_LG_BP60NB10_1.00_MK_HBD.bin
Unplug the drive, wait 5 seconds, plug it back in.
10. Install the latest version of MakeMkv, see your UHD.
