Do you ever have to delete or remove the old stock launcher before or after installing the new one? I ask because I flashed nova launcher and thought I followed the directions to the "T" but when I rebooted the screens did not look right, nothing like the posts said and I could not get the google search bar to remove as it was supposed to do even though I clicked the right option in settings. Then when I tried to unisatll it and wento into CWM recovery the phone just froze with LOADING in big letters and a warning to not turn the phone off!! After 20 min I clicked to START and the phone booted up but was not right. I then decided to flash back to my back up and now I am ok. I would like to use that custom layncher but want to do it right.
