LG BP71n

Post by B1gJ1mmy »

Good evening.

I took a gamble on a external UHD drive on Yahoo Japan. It's logitec branded. Internally it's an LG BP71N(see photo for details) I can't find any info on this forum about it I'm guessing it's not able to be flash modded. The price was good cost me 160AUD with shipping to the motherland so I'm not too upset.

Logitech number is LBD-PWA6U3CLW

Anyone got anything for me (Good or bad news)

I'm guessing it's a BU40N rebrand.
But might as well be safe do a read of the firmware and send it in to Mike the developer he will let you know where to go from there.

Best way for me to reach Mike I'm very new to this forum? I did a firmware dump using sdftool would that be enough.

Thanks.

That will be enough to start but a full backup maybe needed
The developer will tell you the details the forum or email will work to get in touch but since your new you probably can't pm so just email and sent the dump file with it

Ok I sent a message using the contact us a couple of days ago. However I could not attach a file that way. I cant see a direct email or anything.

I'll attach it here just for the sake of it.

This post is pretty old but
FYI
I flashed BU40N on to the BP71N drive (on Linux)
And it now works flawlessly!

On Linux, Kubuntu 24.04, the latest `makemkvcon` 1.18.2 refused to work (hanging). I had to download the 1.17.7
https://www.makemkv.com/download/old/ma ... 7.7.tar.gz
and use the firmware HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin (from the `The all you need firmware pack` ZIP file)
My command was

Code: Select all

makemkv-bin-1.17.7/bin/amd64/makemkvcon f -d /dev/sr0 -f /root/.MakeMKV/sdf.bin rawflash enc  -i /root/mkmkv/HL-DT-ST-BD-RE_BU40N-1.03-NM00000-211810241934.bin
The `sdf.bin` file is listed in Mike's posts.

Thank you for sharing this! You gave me the confidence to try on a recently purchased Logitech branded UHD Blu-ray drive (https://www.amazon.co.jp/-/en/dp/B08KPTZ79H):

Code: Select all

$ makemkvcon f --list
Found 1 drives(s)
00: dev_21:1, /dev/sr0, /dev/sr0
  HL-DT-ST_BD-RE_BU40N_1.03_211810241934_SIK05P7G84331
and it worked well! I basically used the same command you posted, with the exact same firmware. I also had to use MakeMKV 1.17.7, as I had the same hang issue you've written about with 1.18.3.

With makemkv installed to my user profile with GNU Guix, I can now use environment variables defined in libbluray, which VLC relies on, to watch Blu-rays in VLC by setting e.g.:

Code: Select all

export MAKEMKVCON=$(which makemkvcon)
export LIBAACS_PATH=$HOME/.guix-profile/lib/libmmbd
export LIBBDPLUS_PATH=$HOME/.guix-profile/lib/libmmbd
vlc /dev/sr0
The one thing I haven't gotten fully working yet is the BD-J blu-ray menus support also part of libbluray; I can display some background image of the menus, but it hangs after 1 minute and there are no buttons to click. I'll try following-up with upstream (https://code.videolan.org/videolan/libbluray/-/issues) about that.

Thanks for sharing! I bought this one like two years ago through Suruga-Ya but I haven't tried flashing it until literally today. What a timing to find your answer haha.
I flashed the mentioned firmware and I can confirm it works perfectly.
