Started up the bird to check camera settings and for gimbal status it says "Gimbal disconnected". I here the bird making a noise like something is recycling and then I loose video. Last time I flew everything worked fine no crashes or hard landings. Camera goes thru the setup mode. Overal status show "Air Encoder Error (0x800020) restart aircraft.

Just a thought but, with so many having this problem in the past couple of weeks could the DJI Go app have been hacked? I know this sounds sort of riduclus but seems strange that so many are having the same problem recently.

  

Tried to refresh current firmward V01.02.0602 and it failed.

Was able to calibrate the gimbal from the app but still have the "Gimbal Disconnected" error with the same error code. Going to try and give you as much information as I can as I troubleshoot.

I am having the same problem. It seems to be related to the SD card, but trying multiple, valid SD cards, the system still has a problem.
