very short memo

root your android

Sometimes you would like to obtain root privilege on android device. For example, in case that you install applications, which requires root privilege (e.g. bash).

I hereby share with you a quick procedure to do so.

Please be note that unlocking boot loader will lose warrant of your device. I remind you that this procedure shall be done totally under your own risk :-)

backup

You have to backup your precious data of device before you start. Take your time so that you will not lose your treasure.

unlock boot loader

Shutdown your device and boot into boot loader mode by pressing “-” button upon start-up. And then connect android device to your ubuntu and execute following command.

$ sudo fastboot oem unlock

This command execution will unlock boot loader. And lock state will change from “locked” to “unlocked”.

install root application

Download CFA-Auto-Root package, which matches your device and install it.

For example,

$ fastboot boot image/CF-Auto-Root-<device_name>-nakasi-nexus<*>.img

install application

Now your android device is capable of allowing applications to have root privilege.

For example I have installed following applications (some do not require root) to manipulate android.

  • terminal emulator
  • BusyBox
  • hacker keyboard
  • bash
  • vim_touch

Fine. Now I can play with my android any time I want!
