Check the guidelines listed in this post in order to learn how to flash this new factory image for your tablet. The Factory Image can be installed, but you need to know that no data will survive the flashing process.

In order to install this factory image you need to be an advanced user, and you need to know your way around your device’s Fastboot Mode. Before starting the installation process you need to check the following instructions below:

  • use this post only for the LTE Google Nexus 9 tablets.
    – do not use this post for other different devices.
  • enable the USB Debugging from your tablet’s Developer Options menu.
    – if you can’t find the Developer Options you need to go to Settings> About Device and tap seven times on the Build Number section.
    – return to Settings, scroll down and you will find Developer Options there.
    – open Developer Options, find USB Debugging and enable it.
    – if there is an “OEM unlocking” option listed, then you should enable that, too.
  • if your Nexus 9 LTE tablet runs rooted firmware, then you will lose root access.
    – any custom Recovery will be replaced with stock Recovery image.
  • you can flash the update over custom ROMs, too, but you should backup all important files before starting the installation.
  • by installing such factory image you will end up wiping the entire tablet of all data.
    – no files will survive the Nougat 7.0 Factory Image installation.
  • use the tutorial only if you are an advanced user, as we cannot be blamed in case you brick the tablet nor in case you lose any important data in the process.
  • read the whole post and do not skip any steps that we’ve listed in this post.
  • check battery charge level of your tablet, there has to be over 50% charge left before the device switches off completely.

How to flash Android 7.0 Nougat Factory Image for LTE Nexus 9:

You have to setup the Android SDK for your computer in order to make sure that it will detect your tablet when you’ll connect them.

The Android SDK can be downloaded from here. Install all the files on your computer.

Next, find the SDK Manager exe and launch on your PC. It can be found under the SDK installation directory.

Use SDK Manager app to download and install the required Nougat 7.0 and usb drivers.

After SDK Manager does its thing and installs all required files you can continue to the next steps. If the tablet is not detected by your device you have to try and install this other Google usb driver here.

    – ‘platform-tools’ is the folder obtained while setting up the Android SDK on your computer.
  3. Switch off the tablet.
  4. Now boot it in Fastboot Mode.
  5. Connect your Nexus 9 to computer via usb cable.
    – if the tablet is not detected you need to reinstall the USB drivers above.
  6. Go to platform-tools folder and launch a command-prompt in that folder.
    First thing that you need to do is to unlock the Nexus 9 Bootloader, use this command line: fastboot oem unlock
    Confirm.
  7. Next, get to platform-tools folder again and launch the flash-all.bat installer script.
    Confirm the Android 7.0 Nougat installation for device.

Note: the installation process will take a while before it completes. In case the command prompt tells you that some file is not found, and the factory image cannot be installed, then you should try to repeat installation if the installation gets stuck for more than 20 minutes.
