It's just a link compiling to help on process.
Root your device - http://towelroot.com/
Install SuperSU - https://play.google.com/store/apps/d...persu&hl=pt-PT
Have a Custom Recovery - http://forum.xda-developers.com/show....php?t=2261606
Deodex your room (even if stock) http://forum.xda-developers.com/show....php?t=2759511,
AND this Xposed module - http://forum.xda-developers.com/show....php?t=2612179 or here http://repo.xposed.info/module/de.ro...osed.installer - the Xposed Repository is on the second link on main page, you'll need it to run the module. ***this one gives you the SuperUser too, but i used SuperSU from G.Play
