Deleted Firmware DEVO10 HELP!!

I've deleted the firmware of my devo10. Now I tried to put it on but doesn't work. Walkera.com doesn't have the firmware on the site and I do everything to update the firmware but when I want to upgrade the Deveation Dfuse Upgrade tool Says that: "This file doesn't have the right format"

I need help to get firmware on my DEVO10 so it can bind again with my Walkera qr 350 pro

Devo 10 Firmware V0.7: www.walkera.com/en/progoods.php?id=449&type=control

Hello,

Now I use deviation. Works great, except gimbal control.

Does anyone know how to set gimbal control??

Thx
