How to Install Android 11 Developer Preview for Pixel Devices and GSI Builds

The process to install the Android 11 Developer Preview is not overly complex for Pixel 2, 3, 3a, or 4 users, but it requires a few specific steps and some caution. This guide will walk you through the installation process, including how to sign up for the Beta Program and apply the preview build via ADB commands.

Eligibility and Beta Program Sign-Up

Before you begin, you need to ensure that your device is eligible. The Android 11 Developer Preview is currently available for the following devices: Pixel 2, Pixel 3, Pixel 3a, and Pixel 4. If you have one of these models, you can proceed with the Beta Program sign-up. To sign up, visit the Android Beta Program website and follow the instructions to create a Google account if you haven't already.

Sign in with your Google account and check if your device is eligible. If it is, you can opt-in to the Beta Program. In a few days, the Android 11 Developer Preview will be available as an OTA (Over-The-Air) update.

Note on Stability and Risks

It is important to note that the Developer Preview is a beta version and not all apps have been optimized for Android 11, leading to potential crashes or instability.

Before proceeding, remember to back up your data, and proceed at your own risk. This process may damage your smartphone permanently, so it is crucial to have a backup or an alternative phone available in case something goes wrong.

For Non-Pixel Users

If you do not own a Pixel device but you have a Project Treble-supported smartphone or tablet and want to try the GSI (Google System Image) builds of Android 11 Developer Preview, you can follow alternative methods. GSI builds are available for both ARM and ARM64 devices. You can bookmark this page to stay updated as more builds become available.

Steps to Install Android 11 Developer Preview for Pixel Devices

Apply for the Beta Program: Visit the Android Beta Program website to create a Google account if you haven't already or sign in with your existing one. Check if your device is eligible and opt-in to the Android Beta Program.

Download the OTA File: Once your device is eligible, download the Android 11 OTA file. This file will contain the preview build.

Boot Into Recovery Mode: Perform a hard reset on your device. On most Pixel devices, you can do this by pressing the Volume Down and Power buttons simultaneously. Alternatively, some Pixel devices have a Download Mode, but it's not enabled by default. If you are unsure, consult the device manual or Google support. In the recovery mode, select 'Apply Update from ADB'.

Set Up ADB and Universal ADB Driver: Ensure that you have ADB (Android Debug Bridge) tools and the Universal ADB driver installed on your computer. You can download these tools from the official Android Developer website.

Install the OTA File via ADB: Open a Command Prompt (Windows) or Terminal (Mac/Linux) and navigate to the folder where you have the OTA file. Run the command 'adb sideload ota_file_' to start the installation process. Ensure that both your phone and computer are connected to the same Wi-Fi network.

Reboot the Device: Once the installation is complete, reboot your device. You should see the recovery screen. Navigate to the 'Reboot Now' option to restart your phone.

After completing these steps, you should have successfully installed the Android 11 Developer Preview on your Pixel device. However, please remember that this process is still in the beta stage, and you may encounter bugs or other issues. Proceed at your own risk and be prepared to troubleshoot any problems that arise.
