These are the guidelines to root Samsung Galaxy S3 Neo smartphones operating on the Android 4.4.4 KitKat software update. The guide makes use of the CF-Auto-Root application made by popular developer, Chainfire, as well as the Odin flashing tool put together by the official Samsung developers but never officially released.

The CF-Auto-Root file in this guide for the Samsung Galaxy S3 Neo is based on Android 4.4.4 KitKat software updates and the KTU84P.I9300IZHUBNH3 firmware build number. You do not need to be running the KTU84P.I9300IZHUBNH3 firmware on your Samsung Galaxy S3 Neo before you start using our guide to root the device. However, you can use that firmware information as an indicator for your own. Some of the devices in the Samsung range will not boot the older image files.
