I found this thread that should help. Has full instructions and the files you need.
Please read everything very carefully before doing anything. Good idea to read through the thread a bit too to see feedback from others.

And I'll add....if you have further questions it would be best to ask in that thread. They know the device best. The instructions make sense to me, so just read carefully and follow the instructions to the letter.
You need 10 posts under your belt to post in it, so I suggest looking through your device section and commenting and adding "useful" posts where you can to get to you 10 post minimum, so you can post in the first thread I linked you to.
Here's your device section. http://forum.xda-developers.com/gala...74755906220525
If you have issues following the root guide, you could post a thread in the q&a section for your device as well. Will help get your list count up.
Just be very detailed, like the exact issues/errors you got trying to root.
