Required Reading

A GodMode9 script runner is a standalone version of GodMode9 that automatically runs a .gm9 or .lua script when launched. If a script runner is installed to firm 0 it will run a script every time you power on your console, making it difficult to run anything else on the console. When a script runner is launched it checks for the existence of iderped.firm on the root of the SD card and if found will launch the firm instead of running the script; we can use this to launch SafeB9SInstaller and reinstall boot9strap.

Instructions

What you need

Section I - Prep Work

  1. Power off your console
  2. Insert the SD card into your computer
  3. Copy boot.firm, boot.3dsx, and config 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 and rename it to iderped.firm
  7. Reinsert your SD card into your console

Section II - Installing boot9strap

  1. Power on your console. This will launch SafeB9SInstaller
  2. When prompted, input the key combo given on the top screen to install boot9strap
    • If the top screen is blank, power off your console and re-do Section II
  3. Once it is complete (all seven steps on the bottom screen are green), press A to reboot your console
  4. Your console may 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 displays a white notification LED and shuts down when you try to power it on, ensure that you have Luma3DS's boot.firm on the root of SD card (inside Luma3DSvX.X.X.zip)
  5. Press START to save and reboot
