Ahead of schedule, Android 11 Developer Preview is here! The first Android 11 Developer Preview is a bit different from last year's Android 10 Preview because it is extremely early and that means there is no simple wireless installation method yet – although we can expect to see a later version of the Developer Preview with easy installation options.
Unless you have an older Pixel lying around, we definitely recommend that you wait until Android 11 Developer Preview is a bit further. For those who have a spare phone or want to throw caution against the wind, you must install the update manually. Please note that you need a device from the Pixel 2 series or newer, because the original Pixel is not supported.
Without further delay, here is how to install Android 11 Developer Preview.
This is what you need to get started  A compatible Pixel device (2 series or higher) and a USB cable to connect it to your computer.
Now for the actual steps:
Download the correct files
You must download the correct file for your device before you get started. Click here to grab the OTA image for your specific Pixel device. It is also possible to use the full factory images ( here), although that requires extra hoops, such as unlocking your bootloader and more. So if you want to keep it simple, we recommend sideloading OTA.
Prepare your phone
After you have installed the file, you must restart your phone in recovery mode to apply the OTA.
- First switch off your telephone.
- Then press and hold the power and volume buttons simultaneously.
- The boot loader menu is now displayed. Use the volume buttons to scroll to recovery mode.
- Select the recovery mode by clicking the on / off button.
- You will see an Android robot with an exclamation mark. Now press the on / off button and the volume button for about a second.
- Release the Volume Up button to fully recover.
- We then use the volume buttons and scroll to "Apply ABD Update". Press the on / off button to select the option.
- Finally, you see a blank screen with information about sideloading an OTA.
Preparing your PC
Now that your phone is ready, it's time to let the magic happen.
- Connect your handset to your PC via a USB cable. Remember that ADB utilities must be installed on your PC.
- Enter the command prompt in Windows. On Linux or Mac you want to use Terminal.
- You must then enter abd sideload for Windows or ./adb sideload for Mac / Linux.
- Now you want the name of the .zip folder from before. Press enter.
- Once completed, your phone returns to recovery mode and you can remove the USB cable.
- Go to Restart now with the volume keys and press the power button.
That is all. If everything went well, restart now in the Android 11 Developer Preview.
