Warning:

Prerequisites:

• A rooted Samsung Galaxy S3. If you have not rooted your phone yet, please take some time and root it using our easy rooting tutorial.
• The KitKat ROMs we are going to talk about are custom ROMs and therefore they require the presence of a custom recovery like ClockworkMod or TWRP on your device. Not only this, you must have the latest version of the recovery you use. You can download ROM Manager (CWM) or Goo Manager (TWRP) to install the latest version.
