Ever hear rooting android or Jail breaking an Apple device? Well they both are done for Basically the same reason. They are done so you can gain full access to your device. Here you can learn how to root your android device.
By rooting your device you basically become the super Administrator of it.You can edit system files,Change Cpu,Flash custom roms Uninstall System Apps,Run Even more Apps that you normally couldn't,Get free Paid Apps,Run A Vnc Server,and Much More. Rooting is a quite simple process but if done wrong can brick your device.Rooting more than likely voids your Manufactures Warranty.
