Is there a way to reset my T4i back to the factory settings if I can't access the menu settings? Such as a way to 'hard boot' the camera maybe by pressing a certain combination of buttons in a certain order? My menu and info buttons are not working right now so I can't do this the normal way through the menu.
Press the "Info" button several times and you'll see it allows you to display several different things while shooting. One of the choices is to display nothing at all... the screen goes black. If the screen is ever black, you're probably in that mode.
Just press the info button again.
