SDFtool Flasher
Re: SDFtool Flasher
I'm new to this so please be kind...
I've downloaded the SDFtool Flasher and the firmware file (I have a BP50NB40). I can see the list of encrypted firmware. How do I find out what firmware is currently on my drive in order to compare it to the list?
Thank you,
DFex

Re: SDFtool Flasher
When you launch MakeMKV itself, it will show your optical drive model, its firmware version and date. That and the SDFtool Flasher [url]viewtopic.php?f=16&t=22896[/url ] first post will tell you how to flash your drive. Note that your BP50NB40 if SVC: NB52 (a tag on the bottom of the drive) takes a two step process to make it UHD capable.

Re: SDFtool Flasher
I am trying to use the Flasher to enable my LG-WH16NS40 but I get an error message telling me I can't flash this drive. Can someone help me understand what I can do or if there is a fix? This is a brand new, never used drive.

Re: SDFtool Flasher
Near the top of the Ultimate UHD Drives Flashing Guide there's a section that starts with "Stop Read Before Flashing". Item 2 on that list is Drive Platform MT1959. Your drive says it is drive platform MT1939. That's an older drive platform that does not support UHD. The SDFtool is saving you from flashing the wrong firmware onto the drive and rendering it unusable.OneBadTexican wrote: ↑Sat Sep 20, 2025 4:37 amI am trying to use the Flasher to enable my LG-WH16NS40 but I get an error message telling me I can't flash this drive.

The drive you have maybe be new and unused, but it is not modern. If you can, return it.

Re: SDFtool Flasher
As dcoke22 said, it might be new but it is an old drive with the old MT1939 drive platform. The firmware on it is from 2013 so at least 12 years old!!OneBadTexican wrote: ↑Sat Sep 20, 2025 4:37 amI am trying to use the Flasher to enable my LG-WH16NS40 but I get an error message telling me I can't flash this drive.

Can you type here what the label on top of the drive says? Or attach a pic of the label?
Cheers

Re: SDFtool Flasher
Hey, I just wanted to clarify (I don't want to read through 90+ pages of replies, sorry). I just bought the ASUS drive to replace my failing LG 14-40 (purchased and flashed back in 2019?). The pinned post says "If your desktop drive has encrypted firmware, flash WH16NS60 1.02-MK first, then you can either leave it as is or flash any other desktop drive firmware if you want to." Does that mean I need to crossflash the LG firmware first, then flash on the MK 3.10 for ASUS? If so, do I use the recovery tool? Or am I good to just flash the MK 3.10?
Thanks in advance for clarifying.

Flash directly to 3.10MK. But the firmware WH16NS60 1.02MK is the firmware I would use for this drive. Here also: direct flash.
The flasher should check the "enc" check box automatically.

Re: SDFtool Flasher
Thank you Billy. Sadly, I believe you are right. I have contacted the vendor and they will send me a refund. He acknowledged that this is an older model and that his supplier sent this drive without notifying his company. He offered to upgrade the firmware to the latest 1.05 but I chose to just get a refund and buy a new one directly on Amazon even though it will be much more expensive.
I appreciate you clearing this up for me.
Thank you!
Juan

Re: SDFtool Flasher
Ensure you have MakeMKV installed in the default location.
Ensure you are using 64 bit Windows 10 /11.
Post the MakeMKV drive info / libredrive info sections for your drive.
Cheers

I have MakeMKV installed in the default location, I am using Windows 11 64bit, and I am using the most recent firmware package and SDFtool flasher versions available. I am having the same error as the previous users, when i press "start" it does nothing - just stays on "ready". Here's my MakeMKV drive info-

Does your drive have the controller chip mentioned in that post?
