Safemode sets up service sessions for [[NS_Services|ns:su]] and [[Network_Interface_services#nifm:u|nifm:u]].
Safemode sets up service sessions for [[NS_Services|ns:su]] and [[Network_Interface_services#nifm:u|nifm:u]].
It calls [[Network_Interface_services#nifm:u|CreateRequest ]] with '''request_id''' 0x02.
It calls [[Network_Interface_services#nifm:u|CreateRequest]] with '''request_id''' 0x02.
Then calls [[Network_Interface_services#nifm:u|GetSystemEventReadableHandles]] on the returned [[Network_Interface_services#IRequest|IRequest]] and creates an event object.
Then calls [[Network_Interface_services#nifm:u|GetSystemEventReadableHandles]] on the returned [[Network_Interface_services#IRequest|IRequest]] and creates an event object.
After submitting the first request, safemode repeats the request process again and waits for it to finish. If the request fails to finish at this point, [[PCV_services#bpc|RebootSystem]] is called.
After submitting the first request, safemode repeats the request process again and waits for it to finish. If the request fails to finish at this point, [[PCV_services#bpc|RebootSystem]] is called.
It calls [[NS_Services#ns:su|GetISystemUpdateControl]] and creates a system update event by calling:
It calls [[NS_Services#ns:su|OpenSystemUpdateControl]] and creates a system update event by calling:
* [[Network_Interface_services#nifm:u|GetClientId]] to obtain the current client's ID;
* [[Network_Interface_services#nifm:u|GetClientId]] to obtain the current client's ID;
* [[Network_Interface_services#nifm:u|IsAnyInternetRequestAccepted]] with the returned client ID (if no request was accepted, error 0x2A810 is returned);
* [[Network_Interface_services#nifm:u|IsAnyInternetRequestAccepted]] with the returned client ID (if no request was accepted, error 0x2A810 is returned);
* [[NS_Services#ns:su|ISystemUpdateControl cmd2]].
* [[NS_Services#ISystemUpdateControl|RequestDownloadLatestUpdate]].
After this, an event object is created and safemode loops waiting on it while calling [[NS_Services#ns:su|ISystemUpdateControl cmd3]] (update event?).
After this, an event object is created and safemode loops waiting on it while calling [[NS_Services#ns:su|GetDownloadProgress]].
When the system update event is signalled, safemode calls [[NS_Services#ns:su|ns:su cmd0]] (get update status?) and if this fails, [[PCV_services#bpc|RebootSystem]] is called.
When the system update event is signalled, safemode calls [[NS_Services#ns:su|GetBackgroundNetworkUpdateState]] and if this fails, [[PCV_services#bpc|RebootSystem]] is called.
Finally, [[NS_Services#ns:su|ISystemUpdateControl cmd4]] is called and the process exits.
Finally, [[NS_Services#ISystemUpdateControl|ApplyDownloadedUpdate]] is called and the process exits.
