How to Install Android M Developer Preview on Nexus 5, 6, or 9

Today’s announcement of Android M at Google I / O 2015 has already made us very excited. If you want to experience the new popularity (and you have a Nexus 5, 6, 9, or Player), here’s how to get it installed on your device right now.

First, you need to unlock your device. You don’t need root, but you can read more on how to unlock your device in our rooting guide here . You will also need ADB and fastboot installed on your computer and have at least a vague working knowledge of them . Then follow these steps:

  1. Download the factory image for your device here .
  2. Unzip the file and save it in a searchable location.
  3. Connect your device to your computer using a USB cable and make sure debug mode is enabled.
  4. Open ADB Command Prompt.
  5. Enter adb reboot bootloader to access your device’s adb reboot bootloader . (OS X users should add ./ in front of this command.)
  6. Go to the folder containing the factory image.
  7. Enter flash-all to run the installation script. (OS X users, same caveat as in step 5.)

The script will take a few minutes. Usually, devices will delay the boot animation for a few minutes before launching, so if it takes you a while , don’t panic . Once the device boots up, login and have fun!

Warning: This will erase data from your device. Google mentions this on several of its download pages, but in case you missed it, flashing will completely wipe your device and wipe all your data . Be sure to make a backup before proceeding, and don’t try it on a device you absolutely need to work.

If you don’t have a single device lucky enough to be adorned with Android M, you can still check out our previous roundup here . We will also try to find features that Google has not announced. If you spot anything cool, mention it in the comments below! Android M is a developer preview, but the full version (which will have its own name) should be released later this year if last year’s L version is any indication.
