I flew my drone at night recently at night and my daughter has distracted me for a couple seconds, and it was quite windy, and my drone flew dead onto a tree. After picking it up, it failed to turn on, so I opened the drone and a red cable was disconnected, so I hooked it back up with a soldering iron, and it started, after checking all the cables are connected I've put everything back together and booted the drone, it started, everything looked okay, the camera did it's little move and the lights turned on, but now the controller is not linking with the drone itself, I've tried re linking it with 3 different methods, nothing worked, I've checked all the cables are connected on the top of the drone where the motherboard is, and it's all okay. It's just not linking.

Sir, since you drone crashed, I would recommend you contact our support and start a case: http://www.dji.com/support. Please send it back for check and I would not recommend you fix it on your own. Thanks for your support.
