[Q] [S4 ACTIVE SGH I537] How to root and add more display languages? topic

Hey, I am originally just looking to add a Turkish language for a device I just purchased for my dad. But all options require rooting. I followed towelroot and activeroot. Neither worked.

So my question is, is there a way to add languages without rooting? If not, how am i going to root my device and add more languages?
