Update Nexus 9 to Android 5.0 LRX21L Lollipop Factory Image

Nexus 9 can be updated with the Android 5.0 Lollipop LRX21L factory image — the official one released by Google. Android 5.0 is yet to be released for other devices, but Nexus 9 users can download it from the Google Developers website. Nexus 9 already comes loaded with this same build of Lollipop, but it can come in handy when trying to root your Nexus 9 or installing custom ROMs. This is when a factory image can clean your mess when you do something wrong and your tablet refuses to boot up. You can manually update Nexus 9 to Android 5.0 LRX21L factory image from the tutorial below — and root Nexus 9 on this software version.

As you continue reading below, we will guide you through how to backup data, some other important tips and the entire process of how to install Android 5.0 LRX21L on Nexus 9 using the official stock factory image. The only catch is that if this will be your first time playing around with a stock factory image, you might have to unlock your bootloader first before continuing – which means wiping all of your tablet data. This is a full firmware and does not require your Nexus 9 to be on a specific Android version from before. Make sure you read all the step-by-step instructions carefully before performing it. Let’s continue to the tutorial below.

Backup and Other Important Tips

Done with the USB drivers? Perfect. The tutorial is on the next page, but first, please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps:

Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. See below for some tips on how to backup data:

If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your tablet, we strongly recommend you to also backup using that as it creates a complete image of your existing tablet set up.

A few more optional tips that you should remember:

1. Having problems connecting your Android tablet to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean, KitKat and Lollipop.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your tablet goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your tablet might get bricked or go dead permanently. No one wants that, right?

4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your tablet is locked to a carrier, unless we have specified the carrier name or device model.
