Android 7.1 Developer Preview 2 (NPF26F/H) is now available for the Nexus 5X, Nexus 6P, Nexus 9, Nexus 9 LTE and Pixel C, add support devices: Nexus 9, Nexus 9 LTE (Sorry Nexus 6 users…). And this is the final Developer Preview.
How to install Android 7.1 Developer Preview2 without entering recovery?
Usually I prefer use the FlashFire to install Full OTA package rather than use TWRP, As I can do all the step in one, like keep the TWRP recovery, root permissions.
But at this time, There is no Full OTA package download link have been provided by Google, so I just wait someone get the OTA message to extract the hidden download link.
If you have modified the build.prop for using the Google Assistant, you have to restore the original device name and rolling in the Beta programme again to receive the OTA.
Download the factory images of Android 7.1 Developer Preview 2 from Google.

If you use the factory image, remember it will wipe all your data of your phone, if you did not want to wipe data, I would suggest you wait for the Full OTA package.
