How to root your Android

What is rooting the Android?

Android rooting is the process of allowing users of devices running the Android mobile 
operating system to attain privileged control (known as "root access") within Android's subsystem.Android is based on Linux. 

On Linux and other UNIX-like operating systems, the root user is equivalent to the Administrator user on Windows. The root user has access to the entire operating system and can do anything. By default, you don’t have root access to your Android device, and certain apps won’t function without root access.

With root access, you can disable the bloatware that comes with your phone, manually deny app permissions, run a firewall, access the entire file system, or tether your device, even if tethering functionality has been disabled. You’ll find many apps that require root access in the Google Play store (formerly known as the Android Market), although they won’t function until you root your device.

Warnings

Before you root your Android phone or tablet, there are a few things you should be aware of:

• Warranty – Some manufacturers assert that rooting voids your device’s warranty. However, rooting will not actually damage your hardware. You can “unroot” your device and manufacturers won’t be able to tell if it’s been rooted.
• Security – Google Wallet, in particular, has a vulnerability on rooted devices that could allow other apps to access your PIN and other wallet information.  Google Wallet displays a warning message if you run it on a rooted device. If you’re one of the few people using Google Wallet for NFC payments, you may want to reconsider rooting your device.
• Bricking – Rooting a device is a very safe process. However, there’s always some danger of “bricking” a device when you go outside the normal parameters and hack around with it — particularly if you’re trying to root a device or operating system version not supported by a tool. “Bricking” means to breaking the device, making it about as useful as a brick. When you root, jailbreak, or install a custom ROM, or otherwise hack around, you do so at your own risk. It’s a good idea to do a little bit of research first and see if other people report success rooting your device.

Disclaimer: Rooting your device will void its warranty. In addition, performing the rooting procedure incorrectly may have unexpected consequences. Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.

Setup

Here we will use SuperOneClick for root process.

Download here: SuperOneClick

The actual rooting process itself should only take a single click. However, you’ll need to do a few quick things first:

Download and install the Java JDK and Android SDK on your computer before continuing. Java must be installed before the Android SDK.

Enable USB debugging on your Android. On the device, go into the Settings screen, tap Applications, tap Development, and enable the USB debugging check box.

Connect your Android to your computer using its included USB cable. Don’t mount the device’s SD card on your computer – just plug it in.

You’ll also need the USB drivers for your phone or tablet installed. SuperOneClick itself should be able to automatically install the appropriate drivers – however, if this fails, you’ll need to download and install the appropriate drivers from the device manufacturer’s website.

Start here

1. Now you have downloaded and installed SuperOneClick. Open it.

2. Click the Root button in the SuperOneClick window and SuperOneClick should do the rest.

3. The process will take a few minutes. If you run into a problem, you might want to check the XDA Developers forum for your device or do a Google search. 

Once you have completed above process, restart your device after rooting it. You will see the Super User Icon and it means that you have successfully rooted your phone. Keep in mind that on using this method to root Android device will also help you to unroot it, but you can't root it again.
