Hey guys can use your help. Dji phantom 2 vision, I'm getting slow flashing yellow leds (non GPS mode), and when I input csc for motor startup, I get 5 red flashes then back to slow yellow. Here are the steps I took from research, I downloaded software assistance, upgraded firmware, calibrated imu both basic and advanced, check all parameters after calibration to make sure they fell between there range, calibrated TX, and calibrated compass. Everything went good , however same issue on start up. Any help would be appreciated!! Oh, I also sent email to dji, they sent response that they received my email, but, never responded on what I can do to resolve this, that was a week ago.
