- RESTORING APPS & DATA
-It is RECOMMENDED to install apps directly from PLAY after flashing 4.4.2 and NOT allow Google to auto-restore your 4.3 apps & data.
-Some users have had success using Titanium Backup and Rom ToolBox Pro when restoring Apps & App Data (NEVER system apps or data)
but some have had issues as well. - thanks Tada10
-Running previous 4.3 backups on KK 4.4 is NOT advised: galaxies will implode!
Make a Back Up of your new 4.4.2 stock image BEFORE making any choices outside of those recommended by the Devs
