Basic requirements

  1. Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
  2. Make sure your computer has adb and fastboot. Setup instructions can be found here.
  3. Enable USB debugging on your device.

Unlocking the bootloader

  1. Enable OEM unlock in the Developer options under device Settings, if present.

  2. Connect the device to your PC via USB.
  3. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
    adb reboot bootloader
    

    You can also boot into fastboot mode via a key combination:

    • With the device powered off, hold Volume Up + Volume Down + Power.
  4. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    

    If you don’t get any output or an error:

    • on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
    • on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable and port!
  5. Now type the following command to unlock the bootloader:

    fastboot oem unlock
    
  6. If the device doesn’t automatically reboot, reboot it. It should now be unlocked.
  7. Since the device resets completely, you will need to re-enable USB debugging to continue.

Installing a custom recovery using fastboot

  1. Download the PixelExperience Recovery. Simply download the latest recovery file.

  2. Connect your device to your PC via USB.
  3. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
    adb reboot bootloader
    

    You can also boot into fastboot mode via a key combination:

    • With the device powered off, hold Volume Up + Volume Down + Power.
  4. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    

    If you don’t get any output or an error:

    • on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
    • on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable and port!
  5. Flash recovery onto your device (replace <recovery_filename> with the actual filename!):
    fastboot flash recovery <recovery_filename>.img
    
  6. Now reboot into recovery to verify the installation. Do not reboot into the existing OS, since it will overwrite the recovery you just installed!
    • With the device powered off, hold Volume Down + Power.

Ensuring all firmware partitions are consistent

In some cases slot b can be unpopulated or contain much older firmware than slot a, leading to various issues including a potential hard-brick. We can ensure none of that will happen by copying the contents of slot a to slot b.

To do this, sideload the copy-partitions-20210323_1922.zip package by doing the following:

  1. Download the copy-partitions-20210323_1922.zip file from here.
  2. Sideload the copy-partitions-20210323_1922.zip package:
    • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
    • On the host machine, sideload the package using: adb sideload copy-partitions-20210323_1922.zip
  3. Now reboot to recovery by tapping “Advanced”, then “Reboot to recovery”.

Installing PixelExperience from recovery

  1. Download the PixelExperience installation package that you would like to install or build the package yourself.
  2. If you are not in recovery, reboot into recovery:
    • With the device powered off, hold Volume Down + Power.
  3. Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).
  4. Return to the main menu.
  5. Sideload the PixelExperience .zip package:
    • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
    • On the host machine, sideload the package using: adb sideload filename.zip.
  6. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.

Post-install instructions

In some devices flashing a custom avb key to avb_custom_key is supported. Doing this will allow you to lock your bootloader. This step is OPTIONAL.

  1. Make sure your device is in bootloader/fastboot mode.
  2. Download the PixelExperience avb_custom_key Image from Here
  3. Flash the ‘.img’ file via fastboot:
    • On the device, be in bootloader/fastboot mode.
    • From the host machine, flash the image using: fastboot flash avb_custom_key avb_custom_key.img
  4. Now you can lock your bootloader using: fastboot oem lock
