To flash from 103-MK to 1.00, you don't need enc as MK firmware is not encrypted.
Yeah I know it’s not encrypted. It still won’t flash from 1.03-MK to 1.00, so I’m looking for help with that. I don’t know why it’s not working. SDFtool shows progress up to 100% and says it completes, but the drive is still on 1.03-MK.
Try the RECOVER method and see if that works. In the popup window, choose the 1.03-MK firmware currently on the drive, then in the normal firmware selection drop down box choose the 1.00 firmware.
Thanks this worked! I tried using the Recover method before, but didn't select the current firmware in the popup, so that's why it didn't work before. Now that I have this drive on 1.00 it's now reading 4K BDs.
Are there recommended slim drive enclosures that don't have copy protection built in? The one this new drive came with blocks it unfortunately.

Dunno. I suggest just getting the cheapest one you can but I'd be only looking at one's that use a USB-C connection, not a built in cable.

I purchased this on Amazon: External CD/DVD Drive for Laptop, DVD Burner CD Reader for Laptop, 8-in-1 USB 3.0 Portable CD Players for about $18, December, 2025. I removed the included drive & now use it with a BU40N equivalent. I just set aside the included drive (no use for it). This enclosure has an "attached/captured" USB cable with both a USB-C & USB-A connector for power/data (this cable is removable/replaceable inside the inclosure). It also includes a dedicated USB-C port for additional power only & includes an additional USB-C -> USB-A cable for power only. The other features/ports are just "nice to have".
It's worked perfectly for both flashing & ripping 4K/UHD.
Note of course I haven't even gotten to the point of having to read a 4K disc as I haven't yet been able to flash the drive. I continue to successfully burn single and double layer discs from one of the front 3.0 ports on my computer. When I once again get to the point of trying to flash the drive, I'll search out one of the USB ports on the rear of my computer; another option is to go to an older computer that's not connected to a 4K monitor and hook up my new drive to that after installing MakeMKV on it.
I have the display setting scale on my computer set to 300 (which is recommended for my 4K monitor). If I had it set to 100 I wouldn't be able to see any text. (One issue noted with the interface is that the high DPI settings much be changed so the interface is visible and usable.)
I was having the same flashing issues as you were, then I switched to the MakeMKV command-line (wherever you installed MakeMkv, add that to your path). Then open a command prompt and run makemkcon64 f -l (this will list drives available). Then, using the command, run "makemkvcon64.exe f --all-yes -d “ your drive letter here Example: D:” rawflash full enc -i “path to your firmware". You can try with and without the "enc" (stands for encoded firmware). I found that I was missing that "enc". Once I added it, everything worked (using this command-line option.)
Cheers and good luck!
Why am I getting this error? How can I resolve this?

Are you using a real windows 11 64 bit PC or some sort of VM?
I am on a real Windows 11 64 bit PC. A Minisforum MS-01.
What is the SVC code of your drive? It will be written on the label on the side of the box and also underneath the drive. If it is SVC NB72, it is not compatible.
Cheers

It is SVC NB52.
run the flasher as admin
some windows 11 pcs hide drive info from stuff
seen this with the pioneer flasher
