After installing new firmware on a DJI drone, you might see an “Unknown error (code: 180)” message when attempting to start the motors on your drone. That means you’re currently running a version of DJI GO 4 or DJI Fly that is not compatible with the firmware on your drone.
Follow these steps to resolve this issue:
If running DJI GO 4 or DJI Fly on a mobile device, install the latest version of DJI GO 4 or DJI Fly from the Apple store on your mobile device (if using an Apple device) or from the DJI Download Center (if using an Android device).
If using a DJI remote controller with a screen, connect it to Wi-Fi by swiping down from the top of the remote controller screen and install all available firmware updates when prompted. DJI app updates are often included with the remote controller firmware and it’s easiest to let that automatic install process handle everything.
If you’re already using the current remote controller firmware, then manually install the current version of DJI GO 4 or DJI Fly on your remote controller by following these instructions.
