This is the approved revision of this page, as well as being the most recent.

Required Reading

Luma3DS can be installed as a bootloader instead of boot9strap or fastboot3ds, but unless you exactly know what you're doing, you don't want it as it makes updating Luma3DS more difficult and removes some troubleshooting options as it ignores boot.firm on the root of your SD card if it exists. On this page, you will find instructions for going back to boot9strap. If Luma3DS is installed as a bootloader, Booted from SD/CTRNAND via FIRM0/1 will be displayed in yellow on the bottom screen in the Luma3DS configuration menu.


What you need

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 /luma/payloads/ folder on your SD card
  7. Reinsert your SD card into your console

Section II - Installing boot9strap

  1. Press and hold (Start), and while holding (Start), power on your console. This will launch SafeB9SInstaller
    • If you boot to the Luma3DS configuration menu, you held SELECT instead of START
    • If you boot to the HOME Menu, your payloads folder may be incorrectly spelled or in the wrong location
    • If you see a “Luma3DS Chainloader” menu, use the D-Pad and (A) buttons to navigate to and select SafeB9SInstaller from the list
  2. 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
  3. Once it is complete, press (A) to reboot your device
