Hi there, my P4P made a dive in a river... after disassembling the gimbal and drying everything with air and rice for a few days... I reassembled everything: the drone is ok, all parameters fine and seems to fly as always. But I'm not seeing the camera and it says "no transmission signal", in the main page it says "gimbal disconnected"... Note that during startup the gimbal make its setup "dance". Even the gimbal movement from the Rc doesn't work. I double checked the flat cable connections and seems (seems...) all set. Please help!
