Does any one here knows how can I upgrade my 4.2.2 to 4.4 so I can play Pokémon when it comes out over here? I already have it rooted, and I read somewhere that you can upgrade rooted devices, but I found nothing helpful in the internet.
I don't know exactly what device you're using but i find this topic from XDA forums, i think it may help

The third version updated Google Play Store so i hope you can find your game from here. If you still can't get Pokemon Go from Play Store, you can go to http://choilieng.com (another website for downloading apps/games directly from Google Play store)
Good luck!
