The listing, New! Samsung Galaxy S4 Jailbreaking/Rooting! Instructions Only! has ended.
Android 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") within Android's subsystem.
Rooting is often performed with the goal of overcoming limitations that carriers and hardware manufacturers put on some devices, resulting in the ability to alter or replace system applications and settings, run specialized 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.
As Android derives from the Linux kernel, rooting an Android device is similar to accessing administrative permissions on Linux or any other Unix-like operating system such as FreeBSD or OS X.
Root access is sometimes compared to jailbreaking devices running the Apple iOS operating system. However, these are different concepts. In the tightly-controlled iOS world, technical restrictions prevent
1.installing or booting into a modified or entirely new operating system (a "locked bootloader" prevents this),
2.sideloading unsigned applications onto the device, and
3.user-installed apps from having root privileges (or from running outside a secure sandboxed environment).
