In the DJI Go app, it says updates required, the RC controller needs an update, and it can't be updated with the app. I tried updating via SD card, fat32, only the bin file on the card, using a USB adapter, no go. I tried updating via a USB key, no go. I tried updating via connecting a USB cable from the Phantom with the SD card to the controller, no go. The controller just sits there on a green light, never turning blue. The controller is an "A" version Anyone know anything else I can try?
