It calls [[Settings_services#set:sys|GetServiceDiscoveryControlSettings]] to check ~~whether updates need to be installed or not~~. If ~~no updates need to be installed~~ it calls [[PCV_services#bpc|RebootSystem]], otherwise, the process continues.

It calls [[Settings_services#set:sys|GetServiceDiscoveryControlSettings]] to check if '''IsChangeEnvironmentIdentifierDisabled''' is set. If not, it calls [[PCV_services#bpc|RebootSystem]], otherwise the process continues.

It creates and starts a new thread with the sole purpose of setting up the display and showing a progress bar using raw graphics data embedded in the sysmodule's binary.

Line 47:

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.

Line 55:

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|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.
