I had to go a different route to get the keyboard to work. I flashed the zip and went to language & inputs but it said that both Google keyboards were chosen but the 4.1.2 was the one that was working. I had to open the keyboard and long press on the space bar and chose the 4.2 keyboard from that list.

That's what I had to do. Only thing difference is that mine says English US Keyboard, not 4.2. Actually works pretty good, using it to type this now.
