Question [REQUEST] CM-10.2 phone dialer app backport to CM-11

Hi, I've been using cm-11 for a while and the KK dialer app just sucks, google changed something that really shouldn't have changed. Not that much anyways, the whole new concept sucks. "I just want a dialer man". Anyways, I tried backporting the phone app from cm-10 but it didn't work and I couldn't find any guide on backporting this way. My guess is that I was messing something up since this is a system app after all. Any guidance (or if anyone knows how to do it and could do it real quick ) it would be really appreciated.

PS: If I filed this under the wrong category just let me know, this was the more fitting I could find.
