might help to highlight what methods you tried.

Check the first post of [HOW TO]Update Galaxy S4 to Full Stock [MF9] w/ Root & Custom Recovery - xda-developers - read the section titled "HOW TO ROOT STOCK MF9" in the first post.

Before you proceed, read the thread carefully - verify your baseband/build etc
