Also attached zip for flash GSM-fix + bootanimation form stock + SLIM perfomance control + touch sound from Liquid Smooth 2.9.
NOTE: if the build.prop in future versions of the ROMs changes, this may cause problems. Don't be surprised if it does. Don't use it on non-4.3 ROMs unless you like softbricks
