This is a theme I personally use to change the stock experience just a little bit. It mostly gets rid of the gradient backgrounds and grey menus as well as some notification panel changes. This theme will work with any Android 4.2 based ROM But I own a Razr HD Maxx and since there are quite a few AOSP based ROMs out there in good working order now (thanks to the awesome developers) I figured I would share here.

Here is a screen of the Solid Black Dialer. Only thing different between the two.
