Rooting is a process that allows users of cellphones running the Android operating system to attain privileged control (known as "root access") within Android's Linux subsystem, similar to jailbreaking on Apple devices running the iOS operating system, overcoming limitations that the carriers and manufacturers put on such phones. Rooting makes possible to use custom versions of the Android system such as CyanogenMod, supporting features unavailable in stock ROMs. It also allows for newer versions of Android not supplied by the original device manufacturer. In contrast to iOS jailbreaking, rooting is not needed to run applications not distributed by the official Android Market.
Now for the instructions
In this article, I will discuss all kinds of aspects of rooting your Android phone and the benefits that come with it.
Maybe you’ve heard about "rooting" a phone from a friend or read about it somewhere on the Internet. Maybe you even *kind of* know what it is but aren’t sure what you can do with it. Or maybe you are already running a rooted phone and looking for more ways you can utilize it. Whatever the case may be, this article is for you.
What Is Rooting?
First, for the newbies, let me clarify what rooting is. Getting root or rooting your phone is the process of modifying the operating system on your device to grant you complete control over it.
This means you can overcome limitations that the carriers and manufacturers put on your phone, extend system functionality, and even upgrade it to a custom flavor of Android.
The name root comes from the Linux operating system world, where the most privileged user on the system (otherwise known as Administrator on Windows) is called root.
Now, I’d like to take a moment to dispel a common misconception and clarify one thing: rooting does *not* mean installing a custom ROM (a ROM is a modified, "aftermarket" OS).
Installing a ROM may require rooting first, but just rooting can be done in only a few minutes, keeping your stock OS otherwise completely intact.
Usually rooting is fairly simple – in most cases you can find several videos and articles on the web that explain how to do it on your specific phone model – just Google "YOURPHONEMODEL root".
Rooting is not something manufacturers or carriers approve of but they can’t really prevent it from happening because the rooting process usually exploits a vulnerability in the operating system code or device drivers and allows the "hacker" to upload a special program called "su" to the phone. This program, not present or requiring a password by default, is the one that provides root access to programs that request it.
Now an obligatory warning: rooting your phone does run the risk of potentially bricking it (i.e. your phone could become nonfunctional) – so do your homework before attempting anything
Benefits Of Rooting
Let’s check out some of the benefits of rooting your Android phone.
Full Control Over Android
You have access to alter any system files, use themes, change boot images, delete annoying stock apps, such as Sprint’s NFL Mobile live and Nascar Sprint Cup Mobile, and other various native applications that might drive you crazy (Footprints, Voice Dialer, etc).
Back Up The System
On most rooted Android devices, you can back up your entire system to an SD card, much in the same way you can image a hard drive. This is great if you’d like to try a new ROM, as you can back up your phone, wipe it completely, flash the new ROM, and if you don’t like it, you can just restore from your backup and your phone will be exactly how it was before you wiped it.
The easiest way to do this at the moment is by using ‘Rom Manager’ http://www.appbrain.com/app/com.koushikdutta.rommanager(easily installable from the Android Market), developed by famed Android developer Koush.
Rom Manager allows you to easily flash a custom recovery image which is what you will need in order to backup and restore your phone. The recovery image is a special program that can be booted into outside of the phone’s main operating system, sort of like the BIOS on a PC. By default, the recovery image on most Android phones only gives you a few options, mainly related to wiping the phone. Custom recovery images expand upon these options and usually include scripts that can do things like fix your file permissions, or allow you to flash custom ROM’s that the normal recovery image would otherwise reject.
Normally, flashing a custom recovery image requires some command line work, either on your PC, or on a terminal emulator directly on the phone, but Koush’s Rom Manager should automatically flash his custom recovery image (known as ClockworkMod Recovery) for you, provided you’re on one of the phones listed below.
In order to use Rom Manager, you’ll need to make sure you’re using one of the supported devices, and that it is already rooted. Here is the list, as of today:
HTC Droid Eris (CDMA), AKA: Verizon Droid Eris
HTC Hero (GSM)
HTC Hero (CDMA), AKA: Sprint Hero
HTC Dream, AKA: T-Mobile G1
HTC Passion, AKA: Google Nexus One
HTC Magic (Sapphire 32A)
HTC MyTouch/Ion (Sapphire 32B)
Motorola Droid/Milestone
Using Rom Manager is pretty simple. Download and install the application from the market, fire it up, and you’ll be prompted with a disclaimer. If you’re feeling brave, go ahead and hit continue. You’ll be prompted to allow the application superuser permissions during this process – make sure you allow it access.
The first thing you’ll need to do is flash the ClockworkMod recovery image that I mentioned earlier, which can be done right in the app (it’s the first option). Rom Manager should automatically find the latest version of the right image for your phone, download, and install it – the whole process is seamless.
After that is done, you can simply use the ‘Manage and Restore Backups’, and ‘Backup current ROM’ options to, well, backup your current ROM or restore from an existing backup. It’s that simple!

Save Space On Your Phone
Move cache data to SD card
Moving cache data makes for a speedy system. Rooting allows you to save things like browser cache to your SD card to free up space. Its not too complicated a process, but does take a bit of skill. XDA Developer’s have instructions http://forum.xda-developers.com/showthread.php?t=471653posted on their forum if you want to tackle the task, it is definitely worth it.
Move installed applications to SD card
Moving and storing apps on internal memory can significantly slow your device down. If you root, you can avoid that completely.
The easiest way to move applications to your SD card would be to flash a custom ROM that just does it for you (using an app called Apps2SD) – Cyanogen ROM http://www.cyanogenmod.com/is always a good choice.
Run Special Applications
Android-WiFi-Tether or Barnacle Wifi-Tethering – Probably the most useful applications you could utilize on a rooted device. They turn your rooted phone into a wireless access point so that you can effectively share your phone’s Internet connection with laptops and other devices near you, using WiFi or Bluetooth.
These apps are better than similar apps, such as PDANet or EasyTether, because
you don’t have to run special clients on your computer and servers on your phone
you can share a single connection between multiple devices
Super User – allows you to approve or deny root access to any application
Auto Memory Manager – kills tasks you wouldn’t be able to otherwise
Move Cache for Root – move cache for browser, market, maps, street view, and gmail onto SD card
Startup Manager – Clean up android system from system startup to boost system power and memory from the get go
SetCPU for Root Users – Overclocking your rooted device lets you speed up your phone’s processor when you are using it and lets you slow it down when it goes into "sleep" mode. It can either be a battery hog or battery saver.
Install Custom ROMs
The Android custom ROM scene started growing shortly after the first Android phone, the T-Mobile G1, was released. The ROMs that were initially available just offered a few tweaks here and there – access to developer only sections of the operating system, debugging information, and things of that nature.
Now, around 1 1/2 years after the release of the G1, the Android ROM community has grown immensely and ROMs have been developed for most of the Android phones currently on the market.
They’ve gone far beyond simple tweaks and can now give your phone an entirely new look and feel. There are ROMs that can make your phone fly by replacing the kernel with hyper-optimized versions or even overclocking the CPU. The possibilities are nearly limitless and attempting to cover all of the features of all the ROM’s available for all of the phones out there would be pretty much impossible. If you’re interested in flashing a custom ROM on your phone, your best bet is to hit the Googles, search for "phonename custom ROM", see what comes up. You’ll likely find at least one forum dedicated to hacking your phone with plenty of information to get you started.
Here at AndroidPolice, we’re planning a series of custom ROM reviews for as many phones as we can get our hands on. Stay tuned for updates!
Good luck and happy rooting!
Have you rooted your phone? If so, what are you running?

I am No Way Responsible for this if you brick your phone or something goes wrong (although bricked phones can be unbricked)
P.s. Sorry for my English grammar (this is all the knowledge i've personally collected from various people who use andriod phones so please people if you have any knowledge about this please share with others
