Well, it's simple. First check updates of Your Android. After update (if there is any available) plug phone to PC in USB mode 'software' or some like that (I'm from Poland so i have other language of phone) and the most important: enable USB debugging in Settings>Apps>Developer options. After all try to root with SuperOneClick BUT with RageAgainstTheCage exploit!
Oh, and last. Do this on STOCK rom.
