Section IV - safecerthax

1. With your console still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), and while holding these buttons together, power on your console
   • Keep holding the buttons until the console boots into Safe Mode (a “system update” menu)
2. Press “OK” to accept the update
   • There is no update. This is part of the exploit

   • If the console freezes or crashes, force power off the console, then retry this section

Section V - Installing boot9strap

1. When prompted, input the key combo given on the top screen to install boot9strap
   • If a step on the lower screen has red-colored text, and you are not prompted to input a key combo, follow this troubleshooting guide
2. Once it is complete, press (A) to reboot 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

If you came from Black Screen Unbrick return to the page now, and follow the CFW Troubleshooting

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.
