How to change the icons everywhere?

[AC Question]

I have pretty nice icons pack, which works together with Nova launcher. But it changes the icons only at desktop and app drawer. For example App Info and Opened Apps show the original icons. How to change them too?

The launcher controls just the home screens and the drawer. To change those icons on the settings you need to root your phone and check if there's an available ROM for your phone with that option.
