I'm using Exitenz ROM I have install the Gravity Box to have the 5 navigation bar and the Full Mod screen but that don't work ...
Also How you can have the Lockscreen of Z2 ?
First of all, please change your thread title, it has nothing to do with the subject.
About gravitybox, you have to activate it in xposed and reboot. Then, when you activate the navbar option, you have to reboot one more time for it to work.
If you have done all this and it still don't work then I unfortunately can't help you.
