Google’s factory images for the Nexus 9 and Nexus Player are just what you need if you find stock software boring. And good news! You can get factory images for both devices now from the Android developers site.
Factory images are a necessary tool if you somehow botch modifying your device and need to go back to Google’s stock software. They essentially let you wipe the slate clean and start over from scratch.
The devices themselves are available in the Google Play Store and various online retailers. The Nexus 6 is supposed to go back on sale in the Play Store on Wednesday, so we could be seeing the factory image for that soon.

Why this matters: If you plan to root your device, the factory image is your safety net. It will restore your tablet, phone, or media puck back to its original state should things go haywire while installing a custom ROM. Also, the release of factory images is one of the final steps before Google starts pushing out the newest version of Android to existing devices. So if you have a Nexus 4, 5, 7, or 10, hang tight and try not to wear out your finger pressing that “check for updates” button. (It doesn’t speed things up, anyway).
