Ultimate UHD Drives Flashing Guide Updated 2026

Changed it back to R1. Drive still wont recognise the 4k discs. Most frustrating

Are you based in the UK?

If so we could take a look at this drive. It is possible that the communications PCB has developed a fault.

Post your Makemkv info. Maybe you flashed it to a version after Dec. 22. Then it is unusuable for UHD until a fix is available.

Yes based in Aylesbury in Bucks. Would be amazing if you are able to look at it. Just let me know what to do
Thanks

Makes MKV Version 1.17.4

Rest of Drive info and Libre Drive info in a previous post. Fairly certain I could not get the flashing to work as that's how this all started with the errors I was receiving

Email us and we can arrange for someone to have a look at your drive when you post to us. I believe the issue will be the controller which can be repaired or replaced.

I have been looking through the posts and this is slightly beyond what I understand lol. I have this LG drive in the picture. What do I need to do to get it to work for UHD disks ?

What picture? What drive? Model number and age would be helpful knowledge.

Sorry I guess the pic didn’t post.

model- BP50NB40
SVC code - NB50

Soooo.
Running a BH14NS40 drive with version 1.00 firmware.
Following "Ultimate UHD Drives Flashing Guide Updated 2023"
Recommended Firmware to flash for MakeMKV:
WH14NS40 on any Firmware directly to > WH16NS60 1.02MK
(This filename doesnt actually exist in any of the firmware packages I have seen. The closest is HL-DT-ST-BD-RE_WH16NS60-1.02-NM00100-211810291936.bin.)
(I read that the BH and WH are interchangeable.)
Prior to the firmware burn I was able to rip a bluray disk non ultraHD. (Deadpool has two versions in the box.)
I burned the firmware. MakeMKV shows the following but now the drive will not read anything.

Drive Information
OS device name: D:
Manufacturer: HL-DT-ST
Product: BD-RE WH16NS60
Revision: 1.02
Serial number: SIK9QC36M511
Firmware date: 2118-10-29 19:36
Bus encryption flags: 17
Highest AACS version: 46

LibreDrive Information
Status: Enabled
Drive platform: MT1959
Firmware type: Patched (microcode access re-enabled)
Firmware version: 1.02
DVD all regions: Yes
BD raw data read: Yes
BD raw metadata read: Yes
Unrestricted read speed: Yes

The file name BH14NS40_N1.00-A4_patched.exe worked with my drive and has the exact correct model number... which I havent seen in any other file.
Running this file now gives me a checksum error.

Running makemkvcon64.exe f --all-yes -d D: rawflash -i C:\Games\HL-DT-ST-BD-RE_WH16NS60-1.02-NM00100-211810291936.bin does work and says it completes but it is in the same situation.

Anyone have any ideas about how to get this thing working again?
I only own 1 bluray but have a friend who has been making copies of his disks for quite some time. I do have a rare version of the original dune that I want to make a backup of but its just a plain old DVD and I have probably 10 other drives I could do that with.

It almost seems like I may have to do some dos action.
There seems to be a significant gap in information about some of this stuff.
For example NS40 drives. Flashed NS50 on NS40 drive when the instructions say to "WH14NS40 on any Firmware directly to > WH16NS60 1.02MK".
Which seems to be an NS40 drive to NS60? Either contradictory or not enough information.

Is there a comprehensive post that provides the missing pieces? Specifically for the BH14NS40 drive. Every reference I have found has either not been helpful or says to burn the version I have already burned.


"only use the recovery steps for older NS40 drives!!:
Ok here's a summary of what you need to do

Try the recovery option in sdf tool if that fails do this:

Downgrade your drive to WH16NS60 1.00 with sdftool or makemkv command line
Full shutdown pull power plug or flip switch push power button for 10 seconds
Then reflash WH16NS60 1.00 again with the unlocked lg or Asus flasher
Full shutdown pull power plug or flip switch push power button for 10 seconds
Then boot in to your dosflash bootable and dump the firmware https://www.youtube.com/watch?v=eXgybNfHhcg - Obsolete but can be useful for recovery
Use the transfer tool to your correct firmware and flash it.

You killed it as discussed in email there is no recovering unless you PC has ide mode for the sata controller and you stoped talking to me after I asked that.

Hello sjd101,

I received your drive today and decided just to plug it in and test it with some of my scratched discs. I have backed up the first two discs with no problem, and it works fine on my system. I will test five more BD100 discs and then BD66 discs. If it all works, I will clean the lens and parcel and return it. There is no charge at my end, just the postage to England. When you receive it, I will be happy to connect with Teamviewer remotely to sort out any issues with your system. The good news is that Pioneer Drive is working fine so far. Please contact me by email.

Regards Asmcom

Hello sjd101,

I would like to update you further on the drive you sent me that you thought might be faulty. I have tested with three different operating systems, found no faults, and tested with six discs. I conclude that the drive has no problem; the issue is with your computer. There is no charge, so there is no need to worry. Please remember Amazon and online retailers would not give you this assistance, so please remember to support the sellers on this forum who are here to help. I am happy to assist you when you receive the drive back. I will post on Monday morning.

Asmcom

Windows 11 see screenshot below




Apple Ventura 13.5





I will update the picture add Ubuntu Jammy fish 22.04.2 LTS when it is finished processing the disc

Seems like I may have bricked my drive. Would appreciate confirmation or advice from anyone here. Thanks.

Drive is an ASUS BW-16D1HT manufactured September 2021. I flashed DE_ASUS_BW-16D1HT_3.10_MK via SDFtool Flasher. I can open/close the tray, but MakeMKV quickly says no disc is inserted and the drive doesn't sound like it's making an effort to read it. I've tried USB adapters as well as direct connection to the motherboard. I've tried normal dvds, blu-rays, 4k blu-rays. I don't have any luck outside of MakeMKV (e.g. file explorer) either.

Shut down computer and restart it.

No effect. I flashed it a few months back and have rebooted many times since then.

Is this the expected behavior in a "bricked" scenario, though? Drive is recognized by the system, opens & closes, but makes no effort to read inserted discs?
