Long story short, P3 was working great when put on the shelf several months ago. Got it out today in to prep everything for a flight on Monday and wouldn't connect to DJI Go app after updating. Then updated firmware with the latest from DJI website. Everything was appeared to be done and got the success txt file. While sitting for a bit still not able to connect to the app, the camera began to go crazy. I decided to switch back to the older version of firmware. I inserted the sd card with the older version and the thing started producing what sounded like a fire alarm. The P3 is scheduled to fly Monday and don't have time to send it to DJI for repair (their solution to the problem). P3 has never been crashed and only been used two times. Can some one please help me or anyone located around Jackson Ms that could fix this thing ASAP?
