Hi guys, finally i had my own problem with my RC usb port. It does not communicate with my devices (Nexus7 and Samsung S4 mini) as it did since yesterday. I tried to update firmware to 1.3 before 1.4 .... the aircraft went ok but the RC does not work. I cannot access through DJI Go as it does not allow to enter camera view and through a usb stick the rc blinks for a while than it turns off by itself. After that... still no access to camera view from DJI Go. I've read a number of similar threads but I'm still not have a solution.... any suggestion?
