Android 12L, the company’s beta, is expected to be released in 2022. Let’s cross our fingers while we wait for this update. If you have a compatible Google Pixel smartphone, you can check and update your Android version to get Android 12 or 12L version. In most cases, you won’t need to perform a full data reset to update to Android 12 or 12L, but it’s still a good idea to go back. up your data before doing so.

In that guidewe will teach you how to install Android 12 and 12L on Google Pixel and other Android devices. So, without much hesitation, let’s get started.

Sideload Android 12/12L via Recovery and ADB

To install the stable build, you need to sideload the appropriate OTA package to your device from Recovery via ADB. This method will also work for Google Pixel devices with a locked bootloader.

  • Download the update .zip file to your computer here. For convenience, you can rename this file to a simpler name and place the file in the directory where ADB is located on your computer.
  • Optional but recommended: Check the SHA-256 checksum of the file you downloaded to ensure the file downloaded completely and correctly.
  • Enable USB debugging on your phone — Go to Settings > About Phone > Tap “Build number” 7 times, (optionally) enter your pattern, PIN or password to enable Developer Options and navigate to Settings > Developer Options > Enable “USB Debugging”.
  • connect your phone to your computer. Authorize your computer to connect to your phone when the prompt comes up On your phoneif this is the first time you are connecting to this ADB computer.
  • On your computer, run the command.
  • adb reboot recovery

  • Your phone should now be in recovery mode.
  • On your phoneselect the option “Apply ADB Update”
  • On your computer, run the command:
  • adb devices

  • This should return a serial device with the “sideload” next to its name, indicating that your device is connected to the computer in sideload mode.
  • On your computer, run the command:
  • adb sideload “filename”.zip

  • Where “filename” should be replaced with the name of the file downloaded in Step 1
  • The update must be installed on your phone. When the installation is complete, choose “Reboot system now” on your phone to restart on Android 12.
  • Flashing full factory image via Fastboot

    If you have an unlocked bootloader on a Google Pixel device, you will need to update the full factory image of Android 12 or 12L via Fastboot. This is typically done via a flash-all.sh or flash-all.bat script file included in the downloaded file, but their default configuration also cleans the device completely. You can, however, retain your data by deleting the wipe “-w” attribute from the command within the script.

  • Download the factory image .zip file here on your computer.
  • Optional but recommended: Check the SHA-256 checksum of the file you downloaded to ensure the file downloaded completely and correctly.
  • Extract the .zip file and copy and paste the resulting files into your ADB and fastboot folder on your computer for convenience.
  • Optional: The resulting files would contain a flash-all.sh or flash-all.bat script file. Using a text editor, open the flash-all.sh file if you are on macOS/Linux or the flash-all.bat script file if you are on Windows. Find and remove/delete the -w flag in the fastboot update command. This will skip data wiping for your phone. To avoid compatibility issues, a data wipe is recommended.
  • Enable USB debugging on your phone — Go to Settings > About Phone > Tap “Build number” 7 times, (optionally) enter your pattern, PIN or password to enable Developer Options and navigate to Settings > Developer Options > Enable “USB Debugging”.
  • connect your phone to your computer. Authorize your computer to connect to your phone when the prompt comes up On your phoneif this is the first time you are connecting to this ADB computer.
  • On your computer, run:
  • adb reboot bootloader

  • This will restart your phone in Fastboot mode.
  • On your Mac/Linux PC, run:
  • flash-everything

  • This command runs the flash-all.sh script file, which will install the required boot loader, baseband firmware, and operating system. If you’re on Windows, just double-click the flash-all.bat file.
  • When the script finishes, your device will reboot into the new operating system.
  • Install Android 12/12L GSI

    Even if you don’t have a compatible Pixel smartphone, you can still install Google’s official GSI binaries to test Android 12 or 12L as long as your device supports Project Treble. You also need an unlocked bootloader. The last thing we need to say is that updating a GSI will require you to factory reset your device, so be prepared to lose app data before proceeding with this! We recommend that you take a backup off the device (such as on your PC or SD card) in case something goes wrong.

  • Download links for the official Android 12/12L Beta GSIs can be found here. Google has not yet published GSIs based on the stable version. You must download the appropriate version based on your device’s architecture. To see what architecture your device has, run the following command:
  • adb shell getprop ro.product.cpu.abi

  • Optional but recommended: Check the SHA-256 checksum of the file you downloaded to ensure the file downloaded completely and correctly.
  • Extract the .zip file and copy and paste the resulting files (system.img and vbmeta.img) into your ADB folder and fastboot on your computer for convenience.
  • Enable USB debugging on your phone — Go to Settings > About Phone > Tap “Build number” 7 times, (optionally) enter your pattern, PIN or password to enable Developer Options and navigate to Settings > Developer Options > Enable “USB Debugging”.
  • connect your phone to your computer. Authorize your computer to connect to your phone when the prompt comes up On your phoneif this is the first time you are connecting to this ADB computer. On your computer, run:
  • adb reboot bootloader

  • This will restart your phone in Fastboot mode.
  • As mentioned earlier, the target device’s bootloader must be unlocked beforehand.
  • Next, we need to disable Android Verified Boot (AVB). To do this, run the following command:
  • fastboot flash vbmeta vbmeta.img

  • Optional but recommended: Enter the following to wipe the system partition:
  • fastboot erasing system

  • Update Android 12/12L GSI:
  • flash system fastboot system.img

  • Let the image flash, it may take a few minutes. Once that’s done, clean the userdata partition:
  • fast boot -w

  • Finally, restart your device:
  • fast reset

  • Fortunately, your device should boot to the new Android version.
  • Final note
