3. Once completed and the bottom screen says "done.", exit b9sTool, then power off your console
   • You may have to force power off by holding the power button
   • If your console shuts down when you try to power it on, ensure that you have copied boot.firm from the Luma3DS .zip to the root of your SD card

2. Press and hold (Select), and while holding (Select), power on your console
3. Your console should have booted 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
   • For the purpose of this guide, leave these options on the default settings (do not check or uncheck anything)
   • If your console shuts down when you try to power it on, ensure that you have copied boot.firm from the Luma3DS .zip to the root of your SD card
4. Press (Start) to save and reboot

At this point, your console will boot to Luma3DS by default. Luma3DS does not look any different from the normal HOME Menu. If your console has booted into the HOME Menu, it is running custom firmware. On the next page, you will install useful homebrew applications to complete your setup.
