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.
