Red face How to root N9977 correctly

Hi everybody ,

I have a N9977 6inch screen phone, with Android 4.1.1 Build-number e1911_v77_jbaol_g88_v20_20130111
But now I want to root it, so that it can run on Android 4.2 or higher.
Is there a way to correctly root it.
b.d.w. I'm from the Netherlands.
Is there also a way that it update it self, just as a Samsung Note or Nexus phone.
I know it's allot what I'm asking.
