### System Recovery

If Flux is not running correctly due to a failed or invalid update, System Recovery can be triggered by pressing Flux button when powering up. Recovery will execute the factory software instead of any installed update.

If an software update is present on the USB Storage, the factory software will install it and reboot.\
It is recommended to disconnect USB Storage when performing System Recovery to allow connection with the Flow App. Software update can be performed afterwards.
