keyboard_arrow_left Back to the overview

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.
  4. Boot your device with the stock OS at least once and check every functionality. Make sure that you can send and receive SMS and place and receive calls (also via WiFi and LTE, if available), otherwise it won’t work on PixelExperience either! Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.
  5. PixelExperience is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!

Unlocking the bootloader

  1. Enable OEM unlocking and USB debugging in the Developer options under device Settings, if present.
  2. Visit Lenovo’s bootloader unlock page in a web browser.
  3. Fill out the form with your device’s IMEI, serial number, and your email. Complete the captcha and accept the terms that you’re voiding your warranty by choosing to unlock your bootloader.
  4. After some time, you should get an email from devworld@lenovo.com with a link to your unlock token. Download it to your computer.

  5. Connect the device to your PC via USB.
  6. 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 Down + Power.
  7. 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!
  8. Type the following command to flash the unlock token:
    fastboot flash unlock sn.img
    
  9. Now type the following command to unlock the bootloader:

    fastboot oem unlock-go
    
  10. The device will automatically reboot, and your bootloader will be unlocked. Since the device resets completely, you will need to re-enable USB debugging to continue.

Installing a custom recovery using fastboot

  1. Download the custom recovery.

  2. Connect your device to your PC via USB if it isn’t already.
  3. If your device isn’t already in fastboot mode, 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 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 Up + Power.

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 Up + Power.
  3. Now tap Wipe.
  4. Now tap Format Data and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.
  5. Sideload the PixelExperience .zip package:
    • On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
    • On the host machine, sideload the package using: adb sideload filename.zip.
  6. Once you have installed everything successfully, run ‘adb reboot’.
