6. Updateprompt.handleevent

       Case "Update-prompt-apply-result":        this. Handleapplypromptresult (detail);         break;

7. Updateprompt.handleapplypromptresult

8. Updateprompt.finishupdate

Here are two cases, one is gota, only need to restart the B2G process, there is a kind of fota, call Updateservice to complete the work of apply.

Finishupdate:functionup_finishupdate () {if(! This. _update.isosupdate) {      //Standard Gecko+gaia updates would just need to restart the process
      This  . restartprocess (); return; }    Try{ Services.aus.applyOsUpdate (  This . _update); }    Catch(e) { This. _update.errorcode =cr.ns_error_failure;  This. Showupdateerror ( This. _update); }  },
