When the aircraft is connected to the remote controller and a new firmware version is available, the DJI Fly app will send you a firmware update prompt. You can follow the instructions to update the firmware for the aircraft, remote controller, battery, and other devices.

You can also update via the DJI Assistant 2 (Consumer Drones Series) software on a computer.

The latest version of the software can be downloaded from the DJI Air 3S Downloads page on the official DJI website.

Please be aware that certain factors can lead to an update failure, such as:

1. The battery level of the aircraft or remote controller is below 20%.

2. The aircraft or the remote controller is powered off during an update. If this happens, restart the aircraft and remote controller and try again.

3. The network is disconnected during a firmware download.

4. Your smartphone interface is switched to other apps during a firmware download.

The aircraft will restart multiple times during an update and automatically power off after completing the update.
