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. Setup instructions can be found here.
  3. Enable USB debugging on your device.
  4. Make sure that your model is actually listed in the “Supported models” section here (exact match required!)
  5. Boot your device with the stock OS at least once and check every functionality.
  6. LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!

Checking the correct firmware

Installation on your device requires a specific firmware version to be installed before you continue.

  • Firmware refers to a device-specific set of images that are included in, and updated by the stock OS
  • LineageOS builds for this device require an Android 12.0 version of the stock OS to be installed prior to following the installation guide
  • Please ensure that you are checking the Android version, and not the vendor OS version
  • Being on another custom ROM, including unofficial builds of the same version of LineageOS, does not ensure that this requirement has been fulfilled
  • Please re-read this section as many times as necessary to fully understand the requirements

Failing to install the correct firmware version prior to installation may result in failure to install LineageOS, unexpected crashes post-installation, or permanent damage to your device!

Rooting your device

Installing Lineage Recovery using dd

  1. Download Lineage Recovery. Simply download the latest recovery file, named boot.img.
  2. Place the recovery image file on the root of /sdcard:
    • Using adb: adb -d push <recovery_filename>.img /sdcard/<recovery_filename>.img
    • You can use any method you are comfortable with. adb is universal across all devices, and works both in Android and recovery mode, providing USB debugging is enabled.
  3. Now, open an adb -d shell from a command prompt (on Windows) or terminal (on Linux or macOS) window. In that shell, type the following commands:
    su
    dd if=/sdcard/<recovery_filename>.img of=/dev/block/bootdevice/by-name/boot_a
    dd if=/sdcard/<recovery_filename>.img of=/dev/block/bootdevice/by-name/boot_b
    
  4. Reboot into recovery.
    • From the same shell, type the following command:
      reboot recovery
      

Ensuring all firmware partitions are consistent

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

To do this, sideload the copy-partitions-20220613-signed.zip package by doing the following:

  1. Download the copy-partitions-20220613-signed.zip file from here.
  2. Sideload the copy-partitions-20220613-signed.zip package:
    • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
    • On the host machine, sideload the package using: adb -d sideload copy-partitions-20220613-signed.zip
  3. Now reboot to recovery by tapping “Advanced”, then “Reboot to recovery”.

Installing LineageOS from recovery

  1. Download the LineageOS zip file that you would like to install or build the package yourself.
  2. If you are not in recovery, reboot into recovery:
    • Run adb reboot recovery.

  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.

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 Yes. 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”.
