I have also a problem to create a rest file with mkrest.exe - my Main is K770_R8BA024_MAIN_GENERIC_VI_RED53.mbn.

I try also the way over "Run" cmd.exe and the right path to mkrest.exe. The programm said, it has created a file "øK•ðøK•ðøK•ðøK" and now I can use XS for flashing. But the file dont exist on my disk.

So please, can anyone help me?
