Having some trouble here... apologies if I missed something in the earlier scrollback. I have an LG WP50NB40 and I think that I need to perform a two-step process to get it to read 4K UHD blu-rays, per this thread:

WP/BP50NB40 to > BP50NB40-NB50-1.03MK then to > BP60NB10 1.02MK or 1.00MK

That thread also has a section titled "Newer OEM Firmwares and encrypted", with a list of firmware versions which are encrypted. I believe I have completed the first step, but scrolling back in my terminal history to the first `./makemkvcon f -l` command, I *think* my drive was on HL-DT-ST_BD-RE_WP50NB40_1.03_212107081609_SIM22214I3351.

I had downloaded the "New! The all you need firmware pack" link, which is from here, and it contains the following folders:

• Asus 5.25 BW-16D1HT[/li]
  [li]LG 5.25 desktop[/li]
  [li]LG slim BP50NB40-NB50[/li]
  [li]LG slim BU40N[/li]
  [li]LG slim USB BP60NB10[/li]

Although there was no WP50Nb40 folder, I assumed that the bolded item, "LG slim BP50NB40-NB50", was close enough since some other comments indicated as such. That folder contains a single file, "HL-DT-ST-BD-RE_BP50NB40-NB50-1.03-NM00800-212005070917.bin" -- which I don't think is on the recommended upgrade path from the original forum? I copied that .bin file to the /tmp/lg/ directory and tried to flash it with the following command.
The command produced the following output
However, another `./makemkvcon f -l` run showed that it was still on the original firmware. Since the firmware version did not match the guide, I did a little more looking and found a different 'all you need firmware' download called "All You Need Firmware Pack (MartyMcNuts)", which did contain the firmware versions from the original flash path, which I copied into "/tmp/br/". After a few more false starts, where the makemvkcon tool said it had successfully completed but there was seemingly no effect, I found a post that mentioned something about the "enc" keyword, so then I ran the following command:
This command actually succeeded, and when I ran `./makemkvcon f -l` I saw that the firmware had been replaced with "HL-DT-ST_BD-RE_BP50NB40_1.03_212005070917_SIM22214I3351". I believe this now means that the firmware might be unencrypted, if it was encrypted before? Really unsure.

I am now trying to upgrade to the second recommended firmware, "BP60NB10 1.02MK or 1.00MK". I have "DE_LG_BP60NB10_1.00_MK.bin" downloaded from that MartyMcNuts download mentioned above. Unfortunately, I tried to run the following command and it produced another false completion (the device ID seems to have changed with the firmware update).
I tried the following variants: "rawflash main", "rawflash enc", "rawflash enc main", and then I noticed that the Windows-based GUI tool has you select a "RECOVERY" option rather than a "WRITE" option for this second step. After a lot more digging I think I pieced together that this corresponds to "rawflash full" instead of "rawflash main", but I am not really sure. Regardless, running that same command with "rawflash full" doesn't work, and neither does "rawflash enc full" (both indicate that the process completed but then running the `makemkvcon f -l` shows that the new firmware was not applied).

At this point I am able to use MakeMKV to rip a regular Blu-Ray but it does not recognize either of two 4K Blu-Rays that I have tried it out with (keeps whirring up and spinning forever). The "info" section from MakeMKV shows the following: What should I do now? (and thank you in advance for any help!)

If you really did start with a WP50NB40, then I don't think there's bootloader/full flash step. I think that's only when you start with a NB52.

I don't have either kind of drive, so have never had to go through the flashing steps. I might be totally wrong.

But according to the Guide, it should just be two flashes:

It is only the other kind of drive that has the bootloader/full flash step:
