When Google initially announced the arrival of the Android N Developer Preview, they ended up stating that there would be five builds of the software before they end up publishing the public and final release of Android N, which was officially announced as Android 7.0 Nougat at the end of last month. Today, Google has announced the fifth and final build of the Android N Developer Preview, and alongside its announcement they have started to push out the over-the-air updates for DP5 to compatible devices. Users won't have to wait for the OTA to hit their device, of course, as Google now makes the OTA downloads for devices available to flash manually alongside the factory images.
If you're already familiar with the process of flashing new software to your devices manually, then simply pick whether you'd like to download and flash the factory image or the OTA and go to work on the process. The factory images as well as the OTA downloads will be available for the Nexus 5X, the Nexus 6P, the Nexus 6, the Nexus 9, the Nexus 9 LTE, the Nexus Player, the Pixel C, and the General Mobile 4G. It's also worth mentioning that the factory image is also available for the Sony Xperia Z3 for both the D6603 and D6653 model numbers, but to install the software it has to be done through Sony's Xperia Companion software on the PC, which should arguably be a little bit smoother of a process since the software should be taking care of pretty much everything.
If you have one of the other devices and will need to flash either the factory image or the OTA manually, you can find the links to the other compatible devices below. If this is your first time flashing a factory image, be aware that doing so will wipe your device, so you'll want to create backup of anything that you find important and won't want to lose. If you're downloading and installing the OTA software instead you won't have to worry about data wiping, but you should still do a backup just in case, and you'll need to have ADB installed on the computer for either process. If you're ready to get started, click on the link for your device to download the files you need.
