  5. (Optional) Push NikGapps Omni to your device and install the zip. Make sure you include a “nikgapps.config” file in your “/tmp” folder that is configured to install to “system” rather than “product” or “default”.
  6. Reboot to system. You should now be in LOS with Gapps.
  7. (Optional, but recommended): Install Magisk via TWRP
  8. (Optional, but recommended): Run fix script to fix brightness slider not working and to make Magisk work. If you didn’t install Magisk but only want the brightness fix, just enter “n” when prompted in the script. To run the script:
    • NOTE: Script has a .txt file extension to allow hosting on AFH. Remove that so it’s just .sh to match the instructions below.
    • Download and push to device when booted into TWRP
      adb push /tmp
    • Enter an adb shell
      adb shell
