It wasn't full. My problem was it the beta version of the Lollipop.
I've updated the lollipop beta firmware over kitkat and that ****ed up my phone. But I think the problem is solved. Not 100% but, my phone it's ok now.
If you want you can follow the below instructions.
1. Flash with the transitional firmware B800
2. Wipe everything: data and cache. After that i saw that my keyboard is missing. (This was a general bug in the lollipop beta)
3. Flash it with full B609
4. Imediatly after the flash i got a notification for upgrading to B623
5. Done upgrading and now looks ok
