Exclamation ZU Root Help?

Hi.

I rooted my Z Ultra using this method..
http://forum.xda-developers.com/show....php?t=2719677

It worked fine, until I tried to use Root apps. They all come up "grant/deny" etc but dont function properly.

Example: Freedom says "Write permissions on system partition are required in order to use Freedom"

So basically, it's saying it's rooted but can't write any system files.

How can I fix this or is there any other method to root this?

Thnaks.
