Good Day.

I have tried reading some of the post regarding flashing the FW for WH14NS40 to read/rip UHD disc(s). I am still fairly new with flashing drives but not PC bios. I have already dumped the fw of the drive to save a copy of it incase something went wrong. All I need now is guidance on what to do next.

Here is the makemkv information for my BDrive:

Here is the command i used to dump the original firmware: (did i do it right?)

makemkvcon64.exe f -d F: dump auto -o d:\bddump\

100% Operation finished

The Ultimate UHD Drives Flashing Guide says, right at the top, that the drive platform needs to be MT1959. Yours is MT1939. If you try to flash your drive, you'll probably break it.

Thank you for letting me know. Appreciate your response.
