The very first step in rooting is to first unlocking our boot loader. It can be easily through 3 simple steps.

Step 1, we need to install Android Debug Bridge (adb) and relevant tools with a simple apt-get


# sudo apt-get install android-tools-*


Step 2, we need to shutdown our Nexus 10 and boot into bootloader by pressing all three buttons (volume up, volume down, power)

Step 3, which is the last step, is to unlock the device’s bootloader by the following command and then follow the instruction appear on the screen of Nexus 10. Press the volume button to agree to unlock your Nexus 10.


# sudo fastboot oem unlock


That simple! Enjoy :)
