If you would like to learn about fastboot3DS you can read more on it's wiki page, otherwise continue with this guide to move your setup to boot9strap.

Instructions

Section I - Prep Work

1. Power off your console
2. Insert the SD card into your computer
3. Copy boot.firm and boot.3dsx from the Luma3DS .zip to the root of your SD card
4. Create a folder named boot9strap on the root of your SD card
5. Copy boot9strap.firm and boot9strap.firm.sha from the boot9strap .zip to the /boot9strap/ folder on your SD card
6. Copy SafeB9SInstaller.firm from the SafeB9SInstaller .zip to the root of your SD card
7. Reinsert your SD card into your console

Section II - Installing boot9strap

1. Press and hold HOME, and while holding HOME, power on your console. This will launch the fastboot3DS menu
2. Select [+] Boot from file... -> sdmc: -> SafeB9SInstaller.firm
3. You will have booted into safeB9SInstaller
4. When prompted, input the key combo given on the top screen to install boot9strap
   • If the top screen is blank, power off your device and re-do Section II
5. Once it is complete, press (A) to reboot your device
   • Your console may 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
   • For the purpose of this guide, leave these options on the default settings (do not check or uncheck anything)
   • If your device 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
   • 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.
