If you flash a DM600 image, all your settings are set to default. Is that what you mean?
what I meant is that? Like my phone Asus P535, if anything goes wrong with it I just press 2-3 buttons during boot it would be HARD RESET
or in windows deleting/creating new profiles of the current user could solve setting problems too.
so forth I expect in Linux embedded machine, there should be some certain commands wipe-out the profiles and settings, so that it can re-configure like newly installed
