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!

Special requirements

Rooting your device

  1. Download TowelRoot from here.
    1. Click the large lambda symbol to download the apk.
    2. Install and run the apk to achieve root.

Installing a custom recovery using dd

  1. Download a custom recovery - you can download one here.
  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/platform/msm_sdcc.1/by-name/recovery
    
  4. Reboot into recovery.
    • From the same shell, type the following command:
      reboot recovery
      

Installing LineageOS from recovery

  1. Download the LineageOS 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 Home + Volume Up + Power. Let go of Power immediately when the phone vibrates, but keep holding the two other keys.
  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 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”.
