While the Android 6.0 Marshmallow OTA update is nowhere in sight, Google has silently updated its developer page to list the Marshmallow factory images for the Nexus 5, Nexus 6, Nexus 7, and Nexus 9.
The factory images are available for all the Nexus devices, including the 3G/LTE variant of the Nexus 7 and Nexus 9.
- Nexus 5
- Nexus 6
- Nexus 7 (2013) (Wi-Fi)
- Nexus 7 (2013) Wi-Fi + 3G)
- Nexus 9 (Wi-Fi)
- Nexus 9 (LTE)
- Nexus Player
Since the OTA update is not yet available and will take up to a couple of weeks to roll out to everyone, you can flash the Marshmallow factory image on your Nexus device to get a taste of the latest version of Android right away. You can find the steps to flash the Android 6.0 Marshmallow factory image on your Nexus 5, Nexus 6, Nexus 7, or Nexus 9 here.
