What .dfu are you looking for?
The Walkera model configs are .bin files. Furthermore they are TX specific, so we also need to now whics devo do you have?
Deviation model files on the other hand are .ini files.
Or dou you need the firmware file for the Super CP? If I remember well, they are .bin files too...
The dfu extension is for upgrading the firmware of STM microcontrollers, which are used in the devo transmitters...
BTW here you can find everything you can download from Walkera:
