Today we are going to learn something about our mobile phones.

There are several questions...?

Can i change my mobile Operating System.?

If i can change my mobile Operating System than how..?

So i m going to help you to learn how to replace your previous mobile OS using the following method.

First of all you need to know how to start the procedure to make possible change OS.

it's same like computer installation your need to boot your system and than install the windows in DOS mode.

So you need to know first what is Rooting?

Rooting (Android OS)

Rooting is the process of allowing users of smartphones, tablets and other devices running the Android mobile operating system to attain privileged control (known as root access) over various Android subsystems. As Android uses the Linux kernel, rooting an Android device gives similar access to administrative (superuser) permissions as onLinux or any other Unix-like operating system such as FreeBSD or OS X.

Rooting is often performed with the goal of overcoming limitations that carriers and hardware manufacturers put on some devices. Thus, rooting gives the ability (or permission) to alter or replace system applications and settings, run specialized applications ("apps") that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android user. On Android, rooting can also facilitate the complete removal and replacement of the device's operating system, usually with a more recent release of its current operating system.

Root access is sometimes compared to jailbreaking devices running the Apple iOS operating system. However, these are different concepts: Jailbreaking is the bypass of several types of Apple prohibitions for the end user, including modifying the operating system (enforced by a "locked bootloader"), installing non-officially approved applications via sideloading, and granting the user elevated administration-level privileges (rooting). Only a minority of Android devices lock their bootloaders, and many vendors such asHTC, Sony, Asus and Google explicitly provide the ability to unlock devices, and even replace the operating system entirely. Similarly, the ability to sideload applications is typically permissible on Android devices without root permissions. Thus, it is primarily the third aspect of iOS jailbreaking (giving users administrative privileges) that most directly correlates to Android rooting.
