Issues on updating the remote controller and corresponding solutions
Please try to update GL300A remote controllers by using a USB drive/ SD card adapter or connecting the aircraft gimble port with the controller via a USB cable. If you fail updating with these two methods, please connect your controller with your app (meanwhile keep the aircraft off and keep your mobile device connected with the Internet), then turn on your app, go to camera-aircraft status, download and install the firmware and the remote controller will be updated (More than 15 remote controllers in China have been updated in this way).
Remote controllers whose model type is GL300B can only be updated on your app, however, according to the survey, the updates failed in the following three conditions:
First: The remote controller turns off automatically, then the first led light on it turns cyan. And when you connect your remote controller with your mobile device again, the app says no signal, and there’s no notification that says the remote controller needs to be updated.
Solution: It’s possibly because the 1765 module on the remote controller fails updating. So please press these four buttons on the remote controller at the same time, namely, C1, C2, Recording and the Scroll that adjusts ISO, meanwhile, spare another finger to turn the remote controller on (don’t let the other four fingers go), then turn on the app and you’ll be able to download the firmware again and please follow the steps on the app and the remote controller will hence be updated. (More than 10 remote controllers in China have been updated in this way).
Second: The app fails updating the remote controller and the first led light turns red.
Solution: Please update on your app again. (More than 2 remote controllers in China have been updated in this way).
Third: The remote controller won’t update any ways.
Solution: The 1.2.0 Android app has this bug that no matter your firmware is latest or not, the app will ask you to update the remote controller. The new DJI GO Android app will solve this bug. (Many more remote controllers in China have been updated in this way).
