Can't Find WH16NS40 NS50 1.05 Firmware

[wstrater]

I am trying to flash firmware onto an LG WH16NS40 with a ROM version of 1.05, a Svc Code of NS50 and a Manufacturer date of December 2024 from the Linux command line.

This is the drive details from MakeMKV.

Code: Select all

Drive Information
OS device name: /dev/sr0
Manufacturer: HL-DT-ST
Product: BD-RE WH16NS40
Revision: 1.05
Serial number: ##########

Highest AACS version: 53

This is the output when I list the drives with "makemkvcon".

The [Ultimate UHD Drives Flashing Guide Updated 2025][/forum/viewtopic.php?t=19634] lists "HL-DT-ST-BD-RE_WH16NS40-NS50-1.05-N000900-212005061440.bin" but I can't find that firmware.

I have tried "HL-DT-ST-BD-RE_WH16NS60-1.02-NM00100-211810291936.bin" since the write up mentions going directly to WH16NS60 with a WH16NS40. I used the following command and it reports success but nothing changes. I tried with and without "enc" since the downloaded firmware predates 2020 but the current firmware is after 2020.

Code: Select all

makemkvcon f --drive 'dev_21:0' --sdf-file sdf.bin rawflash main enc --in allYouNeed/HL-DT-ST-BD-RE_WH16NS60-1.02-NM00100-211810291936.bin

I am guessing the drive doesn't accept the downgrade.

I have seen some posts about using Windows tools that just "work" but I don't have a Windows machine and I am trying to do this from the Linux command line. I have even looked into some .zip files containing Windows tools and only see 1.02 or earlier versions.

Where can I find the correct firmware?

Thanks,
Wes.

If you read through the linux section of the forum, you'll notice that the last few linux releases seem to have some bugs. Downgrading to 1.17.6 or maybe earlier might get you to a version that can successfully flash your drive.
