So the p4 hit a branch and came down hard enough to do a little damage but nothing crazy. However there were multiple gimbal errors and a navigation system error. Updated firmware and re calibrated imu and compass. Cleared the gimbal errors but not the GPS error. Not the app says"cannot take off" and there are no satellites available and the are a with the satellite is shaded grey. I have taken it apart a little and didn't notice and damage or disconnected wires PLEASE HELP ME DIAGNOSE THIS.
