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.

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.)

Are you using a real windows 11 64 bit PC or some sort of VM?

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.

I have flashed my blu ray drive. Followed your guide. I believe its done correctly. Rips blu ray fine. But the drive does not detect the 4k UHD disk. "no disc inserted." I have unplugged and plugged the drive back in. Tried on different computers. Something I'm missing? It is a WP50NB40 SVC:nb52
