   • If you get the error "This service is not available in your region", use the System Settings to set your device's country to match the region of the system firmware
   • If you cannot access wireless settings, note that the device will automatically connect to any network named attwifi with no password

2. Once it is complete, press (A) to reboot your device
3. Your device should have rebooted into the Luma3DS configuration menu
   • Luma3DS configuration menu are settings for the Luma3DS custom firmware. Many of these settings may be useful for customization or debugging
