What is Rooting/Jailbreaking?

Now that you know the difference between jailbreaking and rooting (or lack thereof), we’ll answer the next obvious question; what is rooting?

In a nutshell, when we root a phone we are actually trying to gain root access (you’ll sometimes here people say Superuser access, which is essentially the same thing). You can basically think of it in the same terms you think of a tree’s roots. The roots of a tree are the very bottom of the tree just as root access is giving us access to the very bottom or most basic files, systems, and commands on our phone. In Linux/Android, the root user is the user with all permissions to change and alter any files on the system/phone.

Why would we want access to these most basic folders and systems on our phone? Well, because these are where things like our phone’s operating systems files are contained and once we have access to them, we can change them to our liking (or we can have someone with some developing experience change them to our liking by flashing a ROM, but we’ll get to that in a sec).

Besides changing our phone’s operating system files, we can also load apps that need root access to run, by that I mean they need access to some of those most basic files and systems to do what they do. A popular example of this, would be the WiFi tethering app, which can turn the phone into a WiFi hotspot so that you can share your 3G/4G connection with other devices in the area. This app needs to access certain features in the phone that are normally not accessible unless we root the phone and then tell it that WiFi tethering has permission to use that root access (yes, even though we have root access, there are measures in place for us to determine what apps can use that privilege and what apps cannot).

IF you don't understand... I have nothing to say...
