  6. Navigate to: Settings > Device Preferences > About > System Update > Local Update.
  7. The TV will scan the USB drive. If it detects update.zip, select it.
  8. Confirm the update. The TV will restart and show a green Android robot with a progress bar.
  9. Do not interrupt – this takes 10–20 minutes. The TV will restart twice.
