3. Create the folder sd:/3ds
   • You may already have this from a earlier section in the guide.
4. Place FBI.3dsx into sd:/3ds/
5. Create the folder sd:/cias/

Section II - CFW Check

1. Hold SELECT, and while holding SELECT, power on the console
   • If the check was successful, your console should have booted into the Luma3DS configuration menu
2. Press START to save and reboot
3. Power off your console

If you do NOT boot into the Luma3DS configuration menu, custom firmware was not installed on your console. Join the Nintendo Homebrew Discord and ask, in English, for help

Section III - Updating the System

1. Update your console by going to System Settings, then “Other Settings”, then going all the way to the right and using “System Update”
   • Updates while using B9S + Luma (what you have) are safe
   • The updater may display a message saying “Your system is up to date” instead of updating. This is normal if you are already up to date; continue to the next section
   • If this gives you an error, set both your DNS settings and Proxy settings to “Auto”
   • If this still gives you an error, follow this troubleshooting guide

Section IV - RTC and DSP setup

1. Close System Settings
2. Press L+↓+SELECT at the same time to open the Rosalina menu
   • If one of these buttons is broken, download this config.ini and put it in sd:/luma, replacing the existing one. This will change the Rosalina menu key combination to X+Y
3. Select “Miscellaneous options”
4. Select “Dump DSP firmware”
5. Press B to continue
6. Select “Nullify user time offset”
7. Press B to continue
8. Press B to return to the Rosalina main menu
9. Press B to exit the Rosalina menu

Section V - CIA Installation

1. Open the Activity Log
2. Press L+↓+SELECT at the same time to open the Rosalina menu
3. Select “Miscellaneous options”
4. Select “Switch the hb title to the current app”
5. Press B to continue
6. Press B twice to return to the Rosalina main menu
7. Press B to exit the Rosalina menu
8. Close Activity Log
9. Reopen Activity Log
   • This should open the Homebrew Launcher
10. Open FBI from the list of homebrew
11. Select SD, then click cias
12. Select the Current directory option, then choose to Install and delete all CIAs
13. Close FBI
    • Six new applications should be on the home menu.

Section VI - NAND Backup and CTRNAND Luma/GM9

1. Power off your console
2. Press and hold Start, and while holding Start, power on your console. This will launch GodMode9
   • If you do not boot into GodMode9, ensure that you copied GodMode9.firm into sd:/luma/payloads/ and that the folders are not misnamed (e.g. luna, lumas, playloads, payload.)
   • If you are prompted to create an essential files backup, press A to do so, then press A to continue once it has completed.
   • If you are prompted to fix the RTC date&time, press A to do so, then set the date and time, then press A to continue.
3. Press Home to bring up the action menu
4. Select Scripts…
5. Select GM9Megascript
6. Select Backup Options
7. Select SysNAND Backup
8. Press A to confirm

10. Select Scripts from Plailect’s Guide
11. Select Setup Luma3DS to CTRNAND
12. When prompted, press A to proceed
13. Press A to unlock writing to SysNAND (lvl1), then input the key combo given
14. Press A to continue
15. Press B twice to exit GM9Megascript
16. Hold R and press START to power off your console
17. Insert your SD card into your computer
18. Copy the contents of sd:/gm9/out/ to a safe location on your computer
    • These files are critical backups and should be backed up to multiple locations (i.e. cloud storage) if possible
    • The two SysNAND files are your NAND backup and can be used to revert your console to a working state if it is bricked by a software issue
    • The essentials.exefs file contains your console’s system-unique files and can be used to recover your data in the event of a hardware failure
19. If you still have them, delete the two SysNAND files from sd:/gm9/out/ from your SD card
    • The essential.exefs file is small and may be kept on your SD card for ease of access

You’re done! Custom firmware is now fully configured on your console.

Information and Notes Here are some key combos that you should know: Holding SELECT on boot will launch the Luma3DS configuration menu. Holding START on boot will launch GodMode9, or if you have multiple payloads in sd:/luma/payloads/, the Luma3DS chainloader. By default, pressing L+↓+SELECT while in 3DS mode will open the Rosalina menu, where you can check system information, take screenshots, enable cheats, and more. This can be changed from the Rosalina menu. If you have a modified Luma config, this key combination may be X+Y instead. Holding START+SELECT+X on boot will make the notification LED show a color for debug purposes. See here for what each color means.

See here for some suggestions on things to do with custom firmware.
