I'm afraid (sure) you havent read the Thread or more than one (maximum) Post.

If you still have done it, there is no reason (and no understanding) for your question.

Read and learn!

In a lot of the Posts in this thread is written, that there is no working version for Android 4.2.2 at the Moment.
And this is exactly the OS Version of S4!

And, so the conclusion, it doesn't work on S4 at the Moment.
