To begin with the custom stuff, the very first thing you need is to gain the root access on your phone. After having it rooted, you will be able to install applications like Titanium Backup, Greenify, System Tuner etc. Having the device rooted will allow you to access the core of your Android system and you will be able to make changes to improve performance and battery life of your device. The second important thing to play with custom stuff is to have a custom recovery installed on your device. There are two popular custom recoveries, CWM and TWRP. Custom recovery allows you to create and restore Nandroid backup, mount your system from recovery mode, wipe cache and dalvik cache, flash zip files of custom ROMs and Mods etc. Now that TWRP recovery is available for our beloved Galaxy Core 2, we will be installing it on this device in the succeeding guide.
