The camera/gimbal LED indicator is blinking RED, ORANGE, GREEN

Try reinstalling the app , then do a full format of the card to see if it helps with the update.

Hi Antonoprianto, our apologies for the inconvenience. Kindly uninstall it and reinstall DJI Assitant 2 by using this link: (https://www.dji.com/phantom-4-pr ... te_search#downloads) and try to upgrade the firmware again. You can also use a different cable so that we can isolate the issue. Thanks for your support.
