If you have already tried rooting your Galaxy S4 mini duos using the old method which requires you to replace your existing kernel with an insecure one first, you probably ended up being in a bad situation such as a bootloop. This is because you are trying to put a kernel based off Jelly Bean onto KitKat.
Also please keep in mind that the downloads included in this post are strictly meant for the GT-I9192 model only. You can check the Rooting category for guides on how to root the GT-I9190 and GT-I9195 (just make sure that the post begins with "(KitKat)" otherwise it is meant for Jelly Bean and you should not try it!).
