Install Android 11 Developer Preview On Pixel 4, Pixel 3, Pixel 3a, & Pixel 2

install Android 11 developer preview

Google has released a very first version of Android 11 as a developer preview. You can now install the Android 11 developer preview on your Google Pixel devices, except for Google Pixel and Pixel XL. As this is a developer preview, you will need to install it via adb and will need a computer. When the beta version of Android 11 becomes available, you can sign up for the Android beta program.

  4. Factory image Android 11 for your Pixel phone.
    • You can download the factory images below.


This is a preview from the developer and we cannot stress this enough. It’s even earlier than a beta version. There will most certainly be bugs and there is no guarantee how small or huge the bugs are. You must understand the risks involved and take full responsibility for your actions. You can proceed with confidence that the method works. However, things can go wrong. In this case, you must understand that you have been warned, and you have gone with it anyway.

In addition, installing the Android 11 developer preview will completely erase your device. Therefore, make sure you have backed up everything that is important, including files and folders to your device’s internal storage.

Create a backup

Creating a backup is never a bad idea. On your Pixel, go to Settings> System> Backup. Here you can see if automatic backup is enabled. If not, activate it. If activated properly, you can also see the date your data was saved. You can also see what data has been backed up. If you think the backup was done fairly recently, you can leave it there.

If you prefer, you can press the Backup Now button to start the backup process manually. The process may take a while, but if things go wrong with Android 11 and you go back to Android 10, you’d be happy to have all of your call logs, contacts, SMS messages, etc.


How to install Android 11 Developer Preview on Pixel 4, Pixel 3, Pixel 3a and Pixel 2

Unzip the downloaded factory image. It would be better to unpack everything inside the platform tools or the adb folder. Launch adb when you are ready. Then connect your device to the computer using a USB cable and restart it in quick start mode with the following command.

adb reboot bootloader

  • Go to the platform-tools folder.
  • Use the flash-all command to start flashing the firmware.
    • On Linux or Mac, use
    • On a Windows machine, use flash-all.bat.

If for some reason the flash-all method fails, you can successfully flash the various components of the Android 11 developer preview manually. To do this, follow the steps below.

  • The first file to flash is the updated bootloader, and this can be done with this command ../ fastboot flash bootloader [bootloader file].img
  • You can see the progress in the terminal or the command prompt window even if you don’t see anything on your phone. After updating the boot loader, restart the boot loader using the following command ../ fastboot reboot-bootloader
  • Now flash the updated radios with this command ../ radio flash fastboot [radio file].img
  • Restart again ../ fastboot reboot-bootloader
  • And finally, flash the image file which will be in zip format ../ fastboot -w update [image file].Zip *: French

When everything is flashing, your device should restart automatically. When it returns, you go directly to the Android 11 developer overview.

Android 11 Public Beta

Every year Google releases the public beta version of a new version of Android to Google I / O. Google I / O 2020 arrives somewhere between May 12 and May 14, so we can expect a release public beta also appeared around this time. There will be three developer previews before that and a total of three Android 11 betas.
