So you may have already tried rooting your new KitKat firmware using the old method but you have ended up with just seeing the Samsung logo. Since the old rooting method required you to flash an insecure kernel, putting a kernel based off Jelly Bean into the new KitKat firmware would definitely not give you good results.
Also please keep in mind that the downloads included in this post are meant strictly for the GT-I9195 model only. You can check the Rooting category for guides on how to root the GT-I9190 and GT-I9192 (just make sure that the post begins with "(KitKat)" otherwise it is meant for Jelly Bean and you should not try it!).
- You need your USB cable
- Samsung USB drivers - A simple installation of Samsung Kies should take care of that.
- Odin 3.07 - Click here.
- CWM Recovery 126.96.36.199 - Click here.
- RootKit - Click here.
