Rooting your smartphone is easy and you can learn how to do it by taking a look at this tutorial. After you root the Galaxy Nexus you will be able to flash new custom ROMs and install applications that usually require root access. Usually, after rooting a device you might be running a security vulnerable device, but you can add new apps and functions that should improve your overall Android experience.

Before starting the root process, you will first have to take a look at the preparation guide below. These guidelines will teach you what you need to do before getting to the How-To Root part of this post:

  • Use this tutorial only for the Samsung Galaxy Nexus I9250 smartphone.
  • Both Takju and Yakju versions of Galaxy Nexus will work with this tutorial.
  • Use the guide if your device is currently sporting the Android 4.3 JWR66V Jelly Bean Firmware version. Though, the SuperSU by Chainfire will most probably work with previous Galaxy Nexus firmware versions.
  • Enable the USB Debugging option from your device’s Developer Options menu.
    > if the Developer Options menu isn’t listed in the Settings menu, then you will need to enable it by opening the About Phone section, scroll down to Build Number and tap this menu 7 times to enable Developer Options.
  • Download and install Android SDK for your PC. Link here.
  • Your computer should have the Google ADK SDK Fastboot drivers from here.
  • Make sure that there is enough power left in your device’s battery, as you wouldn’t want for your smartphone to power off in the middle of the rooting process.
  • Read all the info that I’ve listed in this article and don’t skip any steps.
  • Note that we cannot be held responsible in case you brick your device in the process.
  • This root process shouldn’t remove any important applications from your smartphone.
  • Your Galaxy Nexus should be running on an unlocked bootloader and it should be running the TWRP Recovery image.
  • Your device needs to run the TWRP Recovery image before starting the root process, as otherwise you won’t be able to apply any changes.

If you didn’t install the TWRP Recovery image for your Galaxy Nexus, then you can use the next few steps and learn how to do it successfully:

  • Download the latest Galaxy Nexus ‘maguro’ TWRP Recovery image from here.
  • Place this img file where you have stored the adb and fastboot folders.
  • Power off your smartphone.
  • Boot the Galaxy Nexus into Bootloader Mode.
    > press Volume Up, Volume Down and Power buttons all at the same time and the Bootloader / Fastboot mode will appear.
  • Connect your device with your PC using the USB Data cable.
    > If you have the correct drivers installed, then the Bootloader scren will say FASTBOOT USB.
  • Launch the Command Prompt window where you’ve place the TWRP Recovery img file.
  • Enter the following command line:¬†fastboot flash recovery¬†openrecovery-twrp-2.6.0.0-maguro.img
  • Wait for the installation to complete.

When the TWRP Recovery is successfully installed you can continue with the rest of this tutorial steps. If you have any other questions, please use the comments section listed at the end of this post.

    I did fastboot flash recovery openrecovery-twrp-2.6.0.0-maguro.img and now I have lost all my data and apps, and I can not continue with the process because when I try to enter Recovery Mode I see the Android Avatar with a red triangle and after a while the mobile reboot. I can NOT say thank you for this post.
