Loud beeps remain. 13) There is no response from RC to drone. 14) In DJI GO, shows "No Connection" 15) Camera controls on DJI GO app greyed out. 16) Cannot even format SD card, shows a time out message. 17) No TXT file gets written to the root of SD card showing fail / success. 18) Motors don't even start. WHAT I HAVE DONE 1) DJI GO on the latest IOS version 2.4.3 2) Reistablish pairing with RC and copter succesfully 3) SD Card formatted on another drone. 4) I even tried another SD Card 5) Firmware loaded on SD Card 1.6.0040 from laptop. THIS IS THE STATUS. Is there someone who can give me advice? All cables is fine on gimble - I also had no crashes. Can you please refer me to someone? I know its software and don't want to buy a new drone.
