Android 5.1 is rolling out now for most Nexus devices, but as usual it’s taking a while to arrive on devices. If you’re not keen on waiting around for an update you can take things into your own hands with the official OTA files published by Google. Manually installing an OTA update is not as simply as when it arrives on your phone, but it’s also not terribly difficult to do. Follow along and in no time you’ll have Android 5.1 up and running.

First you’ll need the OTA files for your device. Click (or right-click “Save As”) on the corresponding link below to start downloading. To find your current build number go to Settings > About phone.
