Rooting And Custom Rom
Updated: 12/25/2017 07:17 PM

1. Unlocking Bootloader: Opens the door to the internal memory of the device to be written on to. This allows you to flash images onto the main partitions of the phone. 
2. Installing a Custom Recovery: A custom recovery is flashed onto the recovery partition of the device and overwrites the stock recovery that exists by default. Custom recoveries bring lots of functionality and give you the ability to perform wipes, install flashable zips, create full backups of your NAND (Nandroid backup), and various other features. An unlocked bootloader is needed to install a custom recovery.
3. Rooting: You can gain root by either flashing via recovery a pre-rooted custom rom, or flashing a zip containing the SuperSU binaries. A custom recovery is necessary to do this.
