  1. So I did everything here and got my phone running the ROM. Now I want the phone to look like the Lollipop that Nexus phones have. The real stock one. It looks much nicer than the LG one. Is this possible without launchers and things that will slow down the phone. Originally this was why I followed this tutorial. Little did I know that it doesn’t do what I thought it does.
