So,, I just went through a long process (about two hours) of wiping and installing a rom (well attempting to install) until i just decided to go back completely stock and start over (no root or anything).. The first time i powered the phone on after flashing stock, I had no launcher so i went immediately to googl esearch through the recents page to get nova back. While searching, a google search update appeared and it led me to sign in (as usual) then it downloaded. after a few moments, I noticed That nova hadn't appeared in the status bar as a downloaded app so i pressed the home button-- And the google now launcher appeared. I thought that this was incompatible with JB.. I said all of this to ask what happened? haha I'm just slightly confused.
