I bought a phantom 3 advanced without the controller. I then bought a controller off of ebay. The controllers current firmware is 1.1.8 . I need to use an sd card to update it to 1.3.20 so i can use the dji go app to update it from there but i cant find it anywhere. Does anyone know where i can find that outdated firmware? Thanks a ton. This comunity has helped me so much! -Izak
