THERES NO NEED TO CHANGE PERMISSIONS OR MOVE FILES IN A ROOT EXPLORER.
JUST WIPE CACHE BEFORE FLASHING.
Ive searched almost everywhere i could and was never able to find an easy fix for the ios type emoji's ... So i made a flashable zip( using titanium) that enables the ios emoji keyboard from flipz xylon rom, it works with any rom including stock 4.2.2 . Tried it on three different phones . All the work goes to Flipzmode for maintaining the rom and having emoji support . If this is breaking the rules in anyway , im sorry in advance lol.
