READ THE FOLLOWING BEFORE CONTINUING.
This is a demo. There are bugs in them, its still laggy. Questions Comments or Concerns please go to the right thread. Search your question up before asking, most of the questions you might have might already have been answered. This is not mine, all credit goes to huaweimercuryguru in cricketusers.com for giving us this and the revert back to Gingerbread. Also some credit goes to Anthony S. Burkett for putting everything into one thread for easy find, Sandman45654 for putting a thread on how to root the ICS Update and Erica for making a thread on how to customize your System UI and more.
Follow the directions as told, do not try to make shorcuts and skip a step, double check if its downloaded correctly. If there are any errors downlaod again and try again, check on the download page how big is the file just to make sure it downloaded correctly. Make a backup of you stock rom and have a backup of that as well. If yu have any questions please search on the threads, do not make any new ones, I have seen minimum two questions being aske over and over again. People get frustrated by having to answer the same question more than one, use the search feature. Thank You.
