Crashed my phantom 3 standard and broke the yaw arm on the gimbal. I repaired it and put it back together. I went to test drone and everything works as usual. RC connects to p3 and flies perfectly fine. wifi connects to my device but the app does not produce a camera image or show connection in anything other than gps display. I've checked connections on wires and have tried to re download app. people have told me to do the firmware update but the app does not give the option to do the update. I would appreciate any help I can get!
