No I didn't.....In the main instructions...like for Noobs (which I am not, just been a long time since I have used a different ROM..my excuse and stickin' to it! haha) But it never said to clear cache/data...that I saw anyways...
You seem to know a lot about this stuff....Would you be willing (I hope lol) to PM and send me you're email so I can ask you some stuff. I need a clear answer on a couple things and just want someone to just answer it strait up.
(do you suggest a certain ROM manager to apply you're theme you made?)
