During his presentation at last years Big Android BBQ,Â XDA Elite Recognized DeveloperÂ AdamOutler gave a presentation and showed off a box that was able to automatically root a phone. Dubbed the “Root All The Things Box,” all you needed was to plug in a device and watch the LED indicators on the box. And in a couple minutes the device would be rooted. This magic box was built on a Raspberry Pi.
In this episode , AdamÂ shows how to manually turn on and off GPIOs on the Raspberry Pi. This is the same technique used in the operation of the Root All the Things Box. According to Wikipedia, General Purpose Input/Output or GPIO, is a generic pin on a chip whose behavior, including whether it is an input or output pin, can be controlled or programmed by the user at run time. So check this video out.
