What factors can cause a firmware update to fail?

Top factors include:

1. The battery level of the Mini 5 Pro or remote controller is below 20%.

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

3. The network connection is lost during the firmware download.

4. Switching your smartphone interface to other apps during the download.

5. During the update, the drone will restart several times and will automatically power off once the process is complete.
