Hello guys, here I provide a link to a flashable zip that contains the awesome 4.2 update for nexus 7.
flash it from a custom recovery like always.
here is the link for who can't get the ota update from settings menu.
the file is tested! don't flash it if you are on a custom rom, just stock! enjoy
this is the lockscreen screenshot (made with my phone, I can't take screenshots, I have not root access), just to let you see that is works and is pretty nice
and here you find a link of a video of the most important features on 4.2 provided by philespo, all credits goes to him
