LG BU40N, flashed & can't read 4K UHD (Solved!)

[nicholfd]

LG BU40N, UHD Official Internal Slim Sata 9.5mm in a Vantec NST-510S3-BK 9.5mm slim sata case. Connected directly to USB 3.0 port on Mac mini.

Flashed with MK/HL-DT-ST/BU40N-N-Main/HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin from mk-firmware-pack-20200720.zip, using the MakeMKV sdftool from the app

Flash command & output:

Drive works fine for DVD & Blu-Ray. Can't seem to read UHD. After 12+ minutes of the drive thrashing around, changing speeds, I get (several more lines of the Scsi error lines than below):

Can't read AACS VID from disc - most likely current AACS host certificate is revoked by your drive

LibreDrive compatible drive is required to open this disc - video can't be decrypted.
Failed to open disc

I can move the disc to a 5 1/4" desktop drive and read it just fine (disc is ok). I've tried multiple 4K UHD Discs. Some screenshots attached.

What am I missing with this drive?!?!?

Thanks,
Frank

try a high powered usb HUB

try a high powered usb HUB

Thanks - I'm using a Mac & the USB ports generally offer plenty of power for anything (more than the typical PC). It's showing 900 mA available. I'll find a powered hub, or the "Y" cable that came with the drive chassis and see if that helps.

Thanks,
Frank

try a high powered usb HUB

I found the Y-USB cable that has two USB-A connectors (came with the drive chassis) - PROBLEM SOLVED! Thanks!

I guess it takes more power to read 4K UHD vs. DVD/Blu-Ray?!?!?! I wonder why?

One more quick question - for future firmwares updates, do I still have to use the "enc" option for encrypted firmware?

Thanks,
Frank

[SamuriHL]

There are NO future firmware updates!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Touch not thy drive lest ye find yourself crying. Leave it right where it is.

I cannot seem to make the sdftool to work - tried the same syntax as you but I only get:

-bash: sdftool: command not found

What is wrong? Do you have perhaps a 101-instruction? Or is there an interface in the meantime to flash with MacOS?

Here the drive info:

You need to provide the full command line you attempted to use. You probably left the path off the command line. Where is the sdftool located (on a Mac, it's normally in the MakeMKV app, located in /Applications)? Where do you have MakeMKV installed? What is your current directory (type `pwd` to find out)?

You forgot to include the command line you used to try & flash the drive. Copy/paste what you typed into the terminal when you tried to flash the drive. You probably left off a "./" at the beginning, which indicates the sdftool is in your current directory.

Just to make sure:

My drive is following:

I have the HT-DT-ST folder in "Downloads"

So which syntax is correct being in the folder I am now?

If you stay in the directory you showed above, inside the MakeMKV app, you would start the command line with `./sdftool ` and add the rest of the command line options for your drive.

Hmm... now I'm not sure which file to choose as I probably should downgrade from 1.01 to 1.00 - there seems not to be any 1.00 binary...

Any ideas?

Not me - my knowledge comes from others in this forum, who are much more knowledgable. Maybe search for another thread with your drive, or start a new thread and specifically ask what firmware for your drive.
