Requirements

This guide will reportedly work good for all Google Nexus 7 devices running Android 4.1 Jelly Bean, the latest iteration of Android.

Before We Begin

Before starting with the procedures to unlocking the bootloader of your Google Nexus 7 and rooting it, make sure that you are ready with the following packages:

Before beginning, make sure that your device has USB debugging enabled under Settings -> Developer options.

How To Unlock the Bootloader and Root Google Nexus 7 and Install ClockworkMod Recovery

WARNING! All user data on your device will be cleared!

Take note we must unlock bootloader before we can install ClockworkMod recovery, and we must install ClockworkMod recovery before we can root. This guide shows you how to do three, in the proper order.

To unlock the bootloader of your Google Nexus 7, install ClockworkMod recovery, and root the device, follow the steps below:

  • Connect your Nexus 7 to your computer via a USB cable.
  • Open a command prompt (First, press Win + R to launch the Run dialog, then enter “cmd” in the dialog box).
  • First, change the working directory of the command window to the directory where you had placed the CWM recovery file (recovery-clockwork-6.0.1.0-grouper.img or recovery-clockwork-touch-6.0.1.0-grouper.img) using the command “cd directorylocation” without quotes (for example, “cd c:\android“).
  • Then, in the command prompt, enter the following commands one after another:
    • adb reboot bootloader
    • fastboot oem unlock

      Y
      ou will then be asked to accept and all user data on the device will be wiped.
    • EndFragment–>fastboot flash recovery recovery-clockwork-6.0.1.0-grouper.img or fastboot flash recovery recovery-clockwork-touch-6.0.1.0-grouper.img

For most users, the ClockworkMod recovery would have been permanently flashed to your device after this step. If not, ONLY IF NOT, follow the steps below:

  • Turn off your device.
  • Boot into ClockworkMod recovery mode by keeping the ‘Volume Up’, ‘Volume Down’, and ‘Power’ buttons pressed.
  • Select ‘Mount /System’ from ‘Mounts and Storage’.
  • Then type the following commands one after another in the command window:
    • adb shell
    • cd /system
    • mv recovery-from-boot.p recovery-from-boot.bak
  • You have now successfully unlocked your device and permanently flashed ClockworkMod recovery to your device.

Follow the steps below to root your Google Nexus 7:

  • To start rooting your tablet, go back to the main menu by pressing the ‘Power’ button (or boot into ClockworkMod recovery if you are not already there).
  • Go to ‘install zip from sdcard’ –> ‘choose zip from sdcard’.
  • Select the file JB-SuperSU.zip which you had downloaded earlier.
  • Choose ‘Yes’ to install the zip.
  • Congrats! You now have a rooted Google Nexus with unlocked bootloader and ClockworkMod recovery on your hand (or on your table Winking smile ).

Conclusion

Enjoy your rooted Google Nexus with unlocked bootloader and the extensibility of ClockworkMod recovery. Now you can do things such as block ads [7] or deny apps Internet access [8].
