How to root or un-root your Samsung galaxy S5?

Rooting is the process by which you can gain full control of your Android smartphone. This is basically done to achieve very heavy customizations for a phone.

Advanced users often want to tweak and use more options and also customize their phone to their liking. This is where rooting the device helps them. Certain privileges are gained after rooting that is not available when you first buy the phone. Through rooting, one may completely uninstall the operating system and replace it with another one. This is especially applicable for Android smartphones.

This can be compared to jailbreaking of Apple’s iOS-based phones. Rooting can allow you to access the subsystem of your Android Smartphone. The restriction imposed by the manufacturer can be bypassed easily. What is even better is that you may overclock or underclock your phone to improve its performance, battery life and handle heating issues etc. Even the phone’s firmware can be replaced with a new one that is even better and customizable to a great extent.
