Install LineageOS on
Google Pixel XL

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.
   warning

   Warning: 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 LineageOS either! Additionally, some devices require that VoLTE/VoWiFi be utilized once on stock to provision IMS.
5. LineageOS 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 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 -d 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. Now type the following command to unlock the bootloader:

   fastboot flashing unlock
   

   info_outline

   Note: At this point the device may display on-screen prompts which will require interaction to continue the process of unlocking the bootloader. Please take whatever actions the device asks you to to proceed.
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 Lineage Recovery using fastboot

1. Build a LineageOS installation package. The recovery will be built as part of it!
   warning

   Important: Other recoveries may not work for installation or updates. We strongly recommend to use the one linked above!
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 -d 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 (preferably use a USB Type-A 2.0 one or a USB hub) and port!
   check

   Tip: Some devices have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar ..., fastboot boot ..., fastboot flash ... you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub.
5. Flash recovery onto your device:

   fastboot flash boot boot.img
   

6. Now reboot into recovery to verify the installation.
   • Use the menu to navigate to and to select the Recovery option.
   info_outline

   Note: If your recovery does not show the LineageOS logo , you accidentally booted into the wrong recovery. Please start at the top of this section!

EFS/Persist Backup

1. If you are not in recovery, reboot into recovery:
   • With the device powered off, hold Volume Down + Power. Then use the menu to select Recovery Mode.
2. Now, use the volume buttons to select “Advanced”, and then “Enable ADB”.
3. Now open Terminal (Linux/macOS), or PowerShell (Windows), run adb -d shell, and then run the following commands within it:
   • dd if=/dev/block/sdd9 of=/tmp/modemst1.img
   • dd if=/dev/block/sdd10 of=/tmp/modemst2.img
   • dd if=/dev/block/sdd3 of=/tmp/persist.img
   • exit
4. Now from that same Terminal/PowerShell, run:
   • adb -d pull /tmp/modemst1.img
   • adb -d pull /tmp/modemst2.img
   • adb -d pull /tmp/persist.img

Repartition

1. Download the flashable repartition script from here for 32 GB models, and here for 128 GB models.
2. Rename the downloaded zip file to repartition.zip.
3. On your device’s screen, choose “Apply Update”, then “From ADB”.
4. From your Terminal/PowerShell, run adb -d sideload /path/to/repartition.zip, filling /path/to/ in with the path you downloaded the repartition zip to.
   info_outline

   Note: The repartition script package in question isn’t signed with LineageOS’s official key, and therefore when it is sideloaded, Lineage Recovery will present a screen that says Signature verification failed, this is expected, please click Continue.
   warning

   Warning: This step may take up to 5 minutes, please ensure your USB connection/power source isn’t interrupted during this time.
5. The device will complete the repartition process, and will display Done! on-screen, at this point please select “Advanced” then “Reboot to Recovery”, then proceed with the installation process.

Installing LineageOS from recovery

1. Build a LineageOS installation package.
2. If you are not in recovery, reboot into recovery:
   • With the device powered off, hold Volume Down + Power. Then use the menu to select Recovery Mode.
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 LineageOS .zip package but do not reboot before you read/followed the rest of the instructions!
   • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
   • On the host machine, sideload the package using: adb -d sideload filename.zip.
     check

     Tip: After the package is installed, recovery will inform you that reboot to recovery is required to install add-ons. In case you want to do that, please select “Yes,” otherwise “No”.
     check

     Tip: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.

Installing Add-Ons

1. Click Apply Update, then Apply from ADB, then adb -d sideload filename.zip for all desired packages in sequence.
   When presented with a screen that says Signature verification failed, click Continue. It is expected as add-ons aren’t signed with LineageOS’s official key!

All set!

Once you have installed everything successfully, you can now reboot your device into the OS for the first time!

• Click the back arrow in the top left of the screen, then “Reboot system now”.
