Last night my phantom 2 fall from 3m. No damage from the outside. The battery disconects it self from phantom. I put it back in phantom and turn it on. All I get i fast yellow led lights. It wont search for gps signal or could I start calibration. I connect it to assisten software and seen that gps, and other things works when I move phantom with my hand, but no signal is getting to controler. I tried to connect it with pressing that small red light/button on phantom but it's stays red, manual said it should blink red and turn to green. That doesnt happend. Also the assisten software is showing that phantom is in failsafe mode and I get error CFG-ERR. Can someone help me?
