Nexus 9 users can now install Android M MPZ79M Developer Preview 2 on their devices. This new update comes after the previous preview release that was launched at Google I/O 2015 in May. There are a lot of bug fixes and changes to a few APIs so developers can test and verify their apps before the final Android M is released. An over-the-air (OTA) update is expected to be rolled out in the next few days, but for those who do not want to wait can follow our tutorial below. You can manually update Nexus 9 to Android M MPZ79M factory image from the tutorial below — and root Nexus 9 on Android M Developer Preview 2.
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 M MPZ79M 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.

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:
- Backup your Apps. How? –> How to Backup Android Apps.
- Backup your SMS messages. How? –> How to Backup/Restore SMS Messages.
- Backup Contacts, Gmail and Google Data. How? –> Sync with Google Sync.
- Backup Call History. How? –> How to Backup Call History.
- Backup WhatsApp Messages. How? –> How to Backup/Restore WhatsApp Messages.
- Backup APN Settings: GPRS, 3G, MMS Settings. How? Note down everything from: Settings > Wireless & Networks (More…) > Mobile networks > Access Point Names.
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 Developer Preview 2.
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.
