Follow the steps below to install the latest firmware on your Spark, remote controller, and Spark batteries. Ensure you follow the steps from top-to-bottom. Carefully read each step and ensure you perform them exactly as written.

2) Firmware must always be installed on your Spark, but not all firmware updates need to be installed on the Spark batteries and/or remote controller. Review the Spark release notes so you understand what was changed and you're aware of any special installation instructions.
3) Most of the DJI GO 4 settings are stored directly on the Spark. When installing new firmware on the Spark, those settings will be reset back to the default settings. If you've made any special changes and/or are not sure you'll remember them later, you should document them now so you don't forget them when resetting them later.
4) Confirm that you're using the most recent version of the DJI GO 4 app. If using an Apple device, check the Apple App Store to see if an update is available. If using an Android device, you can check the current version and/or download the latest version of the DJI GO 4 app from the Spark downloads page.
