Install LineageOS on nash

Basic requirements

  1. Make sure your computer has adb and fastboot. Setup instructions can be found here.
  2. Enable USB debugging on your device.

Unlocking the bootloader

  1. Connect the device to your PC via USB.
  2. 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.
  3. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    
  4. Follow the instructions at Motorola Support to unlock your bootloader.

  5. Since the device resets completely, you will need to re-enable USB debugging to continue.

Temporarily booting a custom recovery using fastboot

  1. Download a custom recovery - you can download Lineage Recovery. Simply download the latest recovery file, named something like lineage-17.1-20200707-recovery-nash.img.

  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 Down + Power.
  4. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    
  5. Temporarily flash a recovery on your device by typing:
    fastboot flash boot <recovery_filename>.img
    
  6. With the device powered off, hold Volume Down + Power.

Pre-install instructions

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 work around that by copying the contents of slot a to slot b.

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

  1. Download the copy-partitions.zip file from here.

  2. Sideload the copy-partitions.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.zip

Installing LineageOS from recovery

  1. Download the LineageOS installation package that you would like to install or build the package yourself.

    • Optionally, download additional application packages such as Google Apps (use the arm64 architecture).
  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 LineageOS .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. (Optionally): If you want to install any additional add-ons, click Advanced, then Reboot to Recovery, then when your device reboots, click Apply Update, then Apply from ADB, then adb sideload filename.zip those packages in sequence.

  7. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
