Here is my error message in CMD.

.\makemkvcon.exe f --all-yes -d E: rawflash -i "C:\Users\15030\Desktop\BU40N-FR\fire.bin"
Unable to load sdf.bin
Internal error 0xffffffff

Here is my error message when I try to open SDFtool Flasher

An error occurred trying to start process 'c:\users\15030\downloads\MakeMKV\sdftool64.exe' with working directory 'c:\program files (x86)\MakveMKV'.

When I ignore this error continue to open the software, the dropbox to choice BD drive is empty

Read the troubleshooting section of the guide you may just need to open a bluray or you may need to do the force flash command

Still same error on CMD. 0xfffffff
What's precisely the .net framework version SDFtool Flasher needs?
Maybe I directly installed it again, and it would be fine.
That's what error I get from the SDF tool Flasher. I tried three different win10 64 computers they all show the same error. I tried them on another brand new win7 64 computer, which shows another mistake "Machine lost the 1-1-0.dll.". Actually, the DLL wasn't lost.

The dropdown box in SDF flasher software also is empty. It didn't show any BD/DVD drive

System.ComponentModel.Win32Exception (2): An error occurred trying to start process 'C:\Users\15030\Downloads\MakeMKV\sdftool64.exe' with working directory 'C:\Users\15030\Desktop\SDF(v1.2.4)'. 系统找不到指定的文件。

Caokddjs, Did you ever resolve this? I appear to be having similar issues- same error ID. Have tried with flasher GUI on Win VM and on Mac terminal. No dice. Only difference is I am trying MK HL-DT-ST-BD-RE_BU40N-1.04-NM00500-212005061142.bin
