• When asked for the location of the installation, it is recommended to C://android-sdkplatform-tools since this location will be used for the rest of the steps. For other location, please remember the directory and folder.


• Now, Download the OTA update. It should be in a .zip file.

• Make sure that your device is currently on the “From” Build Number that’s listed for each device. For that open Settings > About Phone and scroll down to About Phone. At the bottom, you’ll find the build number. Make sure it matches the “From” listed below for the device that you’re upgrading. Be sure to update your Android version before installing. The zip file will have a rather large name, so feel free to rename it, so you don’t have to type out the entire file name in the CMD Window.

STEP 6 : Install the OTA Update

Open the Command Prompt in Windows or Terminal on a Mac and navigate to the folder that ADB and Fastboot are installed in If you put the ADB and fastboot to some other location, you should have to navigate to that location. To make things easier, so you don’t have to type out long directories, you can also paste it by pressing ALT and the spacebar, then choose Edit before selecting Paste.

Now that your device is already connected to the PC and USB debugging is enabled, the Fastboot should be restarted. Follow one of the two methods below.

(i) Type “ADB reboot bootloader”

(ii) Turn your device off, and then turn it back on while holding down the relevant key combinations for your Nexus 9 by pressing volume down and power key for 10 seconds.

When you see the start in Fastboot menu, Press Volume Up till it changes to Recovery. Press the Power button to select it.

When You see an Android with a red exclamation icon, press and hold the Power key, then press the Volume up key to show the Recovery Menu.

You will get a new menu. Navigate to apply update from ADB and select it by pressing the Power button.

In the command window — make sure you are in the directory where ADB and Fastboot reside — type: “adbsideload [the full name of the file].zip” without the brackets around the file name.

The update will install and reach 100 percent.

Now, you can restart the phone and the new updated Marshmallow will welcome you.
