Do you want to reboot and your rom doesn't have that shortcut?
Do you want to enter the recovery and you don't want to enter the line manually into the terminal?
Do you want to enter your bootloader to use fastboot and there is no way reboot into it?
Be afraid no more! This simple aplication gives you 3 shortcuts to do all these 3 tasks without having to type the lines into command lines. You just need root permissions and you're good to go!!!
A single click in the icon and boom, the device will do as its told, hassle free, easy and FAST, no interface involved or strange permissions asked, it only does what it's advertised, NOTHING ELSE.
Can't be more easy than this.
* Update the Root calls library
* Update the SDK version
* Add a progress bar after clicking to reboot just to show some visual feedback
