So I updated the aircraft firmware to the current version 1.3.20 with no problems whatsoever. Then I tried to update the controller but it's giving me fits. First tried putting the sd card into the controller but it never found it so i tried it by connecting the controller to the aircraft, same results, didn't find it. I then hooked up my nexus tablet to the controller and clicked on the "update required" button and it downloaded and then they contortI installed it and everything seemed to work perfectly. When I restarted the controller I got the same message that the firmware needed updating so i tried it again and got an error that I needed version 1.3.20 and the current version is 1.3.20!' How is that possible? Anyone have any fixes?
