How to change icon background>

[badboy.edition]

I want to add my own icon background and icon pattern. I was able to change some icons in framework.apk/res/hdpi-finger folder but icon background doesn't change!?

Help is appreciated.

there is a folder with all the files inside framework-res.apk

its a custom folder tho, it has less than 30 icons, vs the TONS of icons on the stock folder.
