Phone Note 2 SCH-N719 GSM Conversion

Hi. I have a Note 2 SCH-N719 and for any reason I cannot install google play or use anything related to google play. I tried to find any roots or custom roms and all this things but I didn't find anything. I wonder if anyone can help me to convert it or to do smth about it.

I have to say that I searched over and over the internet and I couldn't find anything...
