Add a button to update the factory snapshot
It would be nice for nonadvanced users to have a button to update a factory image before. If one resets the router to a too-old version, an update is not possible because of expired certificates. And it is in general more useful to have the newest factory possible if one wishes to reset the router to factory defaults.
