How to Root the original Nexus 7(3G)

It’s not difficult to find the method to root the original Nexus 7 (2012). But I faced a few issues while rooting it and found solutions from many sources. So I thought ill consolidate and document the process in one single post.

Disclaimer: I am not responsible for any damage the process does to your device. Please proceed at your own risk.

  1. Install Helium from the play store into your device. Install the desktop counterpart from here. Now connect your Nexus to the PC and follow the instructions until the Helium is enabled to back up your Nexus. Once its enabled, do a complete backup.
  2. Now don’t forget to copy this backup into your PC. The root process will format your memory and all data will be lost.
  3. I used Superboot. There are many tools out there to root your Nexus, but I randomly chose superboot and didn’t regret my decision.
  4. Download the Superboot zip file above and extract to a directory.
  5. Put your device in bootloader mode – Turn off the phone then turn on with the ‘volume up’ and ‘volume down’ buttons both pressed to enter the bootloader.
  6. Go to the extracted folder and right-click with shift pressed. Select “Open Command window here” from the menu.
  7. In the command window type : fastboot-windows oem unlock
  8. This command will unlock your bootloader.
  9. Once its done, type : superboot-windows.bat
  10. This command will upload a new kernel boot.img to your Nexus 7 and it will root the device when you power it up for the first time.
  11. If all goes well, you are done and you have successfully rooted your Nexus 7 (Mobile)
  12. When you power it up, if it asks for a password to unlock your memory, then you have a few more steps to complete.
  13. If your tablet is on, power it off. Press and hold Power until the device powers on, then immediately press and hold Volume Down (while still pressing Power). You will see the word Start with an arrow drawn around it.
  14. Press Volume Down twice to designate Recovery mode. Press Power to restart into Recovery mode. You will see an image of an Android robot with a red exclamation mark.
  15. While holding down Power, press Volume Up. Use the volume keys to scroll to “wipe data/factory reset” and press Power to select it. Scroll down to “Yes – erase all user data” and press Power to select it.
  16. You are done. You now have a rooted Nexus 7
