I was able to use the latest Hangouts self-patched with Lucky. I can send and receive SMS, Hangouts messages, etc...
Hangouts Dialer (patched or not) is a NO GO. I can call and it's connected but no voice gets through.
Rant: Can't wait for this POS Z10 to break so I can buy a real Android. Too cheap to buy one when this POS still works for most of the things I do.
