Hi there! My first night out with my Phantom 3 Professional was touchy. I took her out of her box, turned her on, and then realized I needed to update her firmware to v1.2.6. The next day: an IMU error. So I recalibrated her IMU—and she flew great, man, did she FLY. Ten flights later, a road trip, and today, I receive an "RC Requires Upgrade" error, accompanied by "Deserializer Disconnected" and the loathsome "IMU Error". Except this time, the option to calibrate IMU is greyed out in the Pilot App, and the camera no longer feeds video to the iPhone (No Signal). I've fiddled with the SD card, tried re-updating the firmware (the resulting read me .txt says the firmware is already installed), updated iOS, and I even tried flying her (yes, she still flys). But no video feed, and no recording capability. One curious thought I have goes back to that first IMU error. Before I knew how to calibrate the IMU, the Phantom's gimbal was limp until I stuck my fingers into her serial ports—at the top of the gimbal. Suddenly, her gimbal sprung to life. However, this didn't solve the IMU error, so I later calibrated it. Any thoughts on what might wrong with Audrey?
