Welcome to XDA! Since someone else answered the same question you posted in a different thread (see http://forum.xda-developers.com/show...&postcount=751), I'm going to move this thread to Q&A (remember to post all questions in Q&A) and close this thread. I like your idea of trying to make your own ROM. Good luck!
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
