I just bought the 3dr solo off ebay and I have been running into some problems updating the software. When I start up the controller it says pre flight update so I went on to side pilot and loaded open solo on both the controller and the drone. Then when I try to fly the drone it makes a beeping sounds everytime that I press the fly button and it wont take off. Is there anyway for me to be able to fix this or should I just sell the drone and give up Ive tried everything.
