    Oh funny. But chance you choose the exact same name for your kernel, as Superdragonpt and me did. 

    Oh wait…You just used our kernel without mentioning it. 

    Are you going to copy and paste more stuff from other developers (redmi note 2 for example)? Then this rom really could be great…Oh, typo, I meant to say deleted…Lol
