For those of you who are looking to get the Android 5.1 today not tomorrow, this tutorial will show you how to update your Nexus 4, 5, 6, 9, or 10 to the latest Android 5.1 and root it.

UPDATE: Also works for Android M Preview but DO NOT install SuperSU as you will soft brick! (Cannot root M Preview atm.)

Android 5.1 comes with some nice performance/ram tweaks to make your Nexus device a bit faster plus cool features like drop-down WiFi/Bluetooth menus and more!

*Note – This method works for all Nexus devices and also works for other versions of firmware such as KitKat.

Who this tutorial is for:

  • For people with a rooted Nexus device who want to update to Android 5.1 with root.
  • For people who want Android 5.1 and root and have a custom ROM on rooted Nexus device.
  • For people who want to install latest Android 5.1 bootloader and radios. (Could make your network faster/better, get better signals.)

This method WILL NOT ERASE ANYTHING on your Nexus device.  If you are already on a stock firmware/ROM, you can skip the “Wipe/Factory Reset” step in the video, it will simply upgrade you to latest Android 5.1 + root.  If you are on custom ROM, you will probably have to do a “Wipe/Factory Reset” so backup your ROM and/or apps using Titanium Backup app FIRST!

Before we begin, we assume you already have an unlocked bootloader on your Nexus device.   If you don’t know what this is, you probably shouldn’t be following this tutorial.

Download the Files you need in the video tutorial:

  • Download firmware here on our Nexus Android 5.1 Firmware page or on Google’s site. (For Android M Preview, go here instead)
  • fastboot.zip – This contains all the fastboot files you need for all Windows, Mac, or Linux.  You DO NOT NEED to download the whole Android SDK, we just saved you an hour downloading the SDK, this is ALL YOU NEED!
  • Android USB Drivers – For Mac or Linux, YOU DO NOT NEED DRIVERS.  For Windows, you will need Android USB drivers, please see video tutorial on how to install these drivers.
  • SuperSU – You will need this to root Android 5.1.

NOTE: For Nexus 6, you will need to use this fix along with the below tutorial!

    When I’m doing the “fastboot flash system system.img” command it says “load_file: could not allocate 1778070480 bytes
    error: cannot load ‘system.img’

    Any idea what might be wrong? I’m on a Nexus 6, rooted and bootloader unlocked
