Hi,Could you help with this, I have an BU40N drive that shows up in MakeMkV with this drive information:
Drive Information
OS device name: E:
Manufacturer: HL-DT-ST
Product: BD-RE BU40N
Revision: PA05
Serial number:
Firmware date: 2120-06-11
Bus encryption flags: 1F

is it possable to flash the drive?

I'm trying to flash the unit and I get error code 0x82052400.

Are you flashing it with BU40N 1.03-MK?

Hello, I'm trying to rip some UHD Blu-rays and I'm stuck on a persistent issue with my drive.

My goal is to flash my LG BP60NB10 drive to enable LibreDrive and rip UHD discs.

My Setup:

Drive Model: HL-DT-ST BD-RE BP60NB10

Firmware Version: 1.02 (Original)

Operating System: macOS

Tool: makemkvcon via Terminal

The Problem:

I have successfully flashed my drive multiple times. Each time, the terminal output shows Done successfully, confirming that the flashing process has completed.

However, when I check the drive information in MakeMKV, it still reports Firmware support: No and Firmware type: Original. The drive consistently fails to enter LibreDrive mode.

What I have tried so far:

Multiple Firmware Files: I have tried flashing with different firmware files, including those labeled as UHD-friendly and MK firmware from the forums.

Disconnect/Reconnect: After each successful flash, I have completely unplugged the drive from my Mac and plugged it back in.

Drive Identifier: I have verified the correct drive identifier using makemkvcon f -l before each flashing attempt.

Dump File Submission: I submitted a dump file to the forum, but was told it was useless because LibreDrive was not activated.

I am puzzled as to why my drive's firmware status remains "Original" despite the successful flashes. Am I missing a crucial step for macOS? Is there a specific firmware file for this drive model that I should be using? Or could this be a hardware-related issue?

Hey,

Thanks for putting this together. I need to flash my drive so i can rip some UHDs but i'm a bit confused about which firmware step i need to follow

here is my drive info from makemkv:

Code: Select all

Drive Information
OS device name: E:
Manufacturer: HL-DT-ST
Product: BD-RE WP50NB40
Revision: 1.03
Serial number: SIM22214I5041
Firmware date: 2121-07-08 16:09
Bus encryption flags: 17
Highest AACS version: 81

LibreDrive Information
Status: Possible, not yet enabled
Drive platform: MT1959

so i have a WP50NB40 with SVC code NB52, and im a tad bit confused about which downgrade path i need to take

WP/BP50NB40 to > BP50NB40-NB50-1.03MK then to > BP60NB10 1.02MK or 1.00MK
NB52 to > BP50NB40-NB50-1.03MK with enc > BP50NB40-NB50-1.03MK with bootloader/full flash > BP60NB10 1.00_HBD from Marty download/file.php?id=2143

is that first line for NB50 SVC code only so i need the second (annoying) path?

I have tried again with the 'enc' flag as you suggested.

I used the following command:
./makemkvcon f -d '/IOBDServices/AFC9B139' -f /private/tmp/sdf.bin rawflash main enc -i /private/tmp/HL-DT-ST-BD-RE_BP60NB10-1.02-NM00800-212005070935.bin

The terminal showed Done successfully once again.

second line.

is it possible to use the SDFtool flasher instead of the command line?

the SDF thread has this in it:

Code: Select all

For the moment, to flash the BP50NB40 SVC:NB52, using the latest SDFtool Flasher, follw the steps below:

1. Flash the drive to BP50NB40 (NB50) 1.03-MK.

Now for the crossflash:

2. Select the RECOVERY option and in the pop up, select the BP50NB40 (NB50) 1.03-MK firmware that you just flashed.
3. Select the BP60NB10 1.00-MK or BU40N 1.00 firmware in the normal drop box.
4. Click START

what is the difference between the WP40NB50 and the BP40NB50? I can't for the life of me find what is different between them. It seems like they use the same firmware upgrade path regardless of which one you get, but i want to make sure i'm not conflating 2 separate things.

There are no differences between the BP50NB40 and WP50NB40.

Yes you can use SDFTool Flasher if you are using 64 bit Windows 10 or 11. I recommend using the BU40N 1.00 firmware as it is compatible with all good ripping software. Just follow the instructions exactly and watch the gif a few times if needed.

Hi guys,
Is one of these new Asus external drives UHD friendly? Can you use these to rip UHDs?

Asus BW-16D1H-U Pro
Asus BW-16D1X-U
Asus SBW-06D2X-U

I had a question about the "include boot loader" checkbox since it states on mouseover that it helps with the BP40NB50 drives flash, but the instructions didn't specify to check it nor was it checked in the gif, so i left it unchecked and went ahead with flashing it to BU40N 1.00.

It appears to be working as intended! I'm currently ripping my UHD Blu-ray of Ghost in the Shell, with its sequel and Akira next. Very excited!

Thanks for all the hard work you've put into this guide and the hundreds of pages of follow-ups!

Cheers!
