Search is your friend....Been cover thousands of times on forum already..

But there is one thing Im not getting, how are you rooted with z4root but unrooted with the one click method, those are developed by two different developers and there is no guarantee that it would remove all the root data from z4root.

I suggest SBF the device back to stock.
