Major thanks to Rivertamer for his help testing!
IMPORTANT: Tiffany84 has just created flashable files for users, the links are below the animated gif. The original files still attached to the post are not flashable and require adb push or copying from your sdcard to the appropriate system directory.
Thank you againTiffany84 for packing this up in flashable zips for everyone.
