Well feces, I wish I knew what to tell you. I'm honestly surprised no one here has chipped in. I figured someone would know. You may wanna head over to xda forums and ask it there. That group is way more into rooting with stock and custom roms. They'd probably be more qualified to assist you.
EDIT:. Lol! I can say feces, but the language filter, filters out the p word for feces xD.
