What factors can lead to an update failure on my Mavic 4 Pro?

The following factors can lead to an update failure...

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