Orange Klif unlock error

Drivers are ok,but it remain stuck at this:

Searching phone;
Phone detected (PreLoader USB VCOM (Android))
Preparing to start meta mode;
Searching for debug port; (be sure drivers from support were installed)
Debug Port found on Android Gadget VCOM Driver (COM25);
Preparing to connect meta mode;

And nothing,what can be wrong?Thank you
