### Required Reading

The file `boot.firm` is what is launched by boot9strap itself after it finishes loading off of NAND. In this case, we are using Luma3DS by [LumaTeam](https://github.com/LumaTeam/) to patch the device, allowing it to run homebrew software.

On this page, we will make critical system file backups and install the following homebrew programs:

+  **FBI** *(installs CIA formatted applications)*
+  **Anemone3DS** *(installs custom themes)*
+  **Checkpoint** *(backs up and restores save files for 3DS and DS games)*
+  **Universal-Updater** *(a homebrew app store for downloading homebrew from the 3DS over Wi-Fi)*
+  **GodMode9** *(multipurpose tool which can do NAND and cartridge functions)*
+  **Homebrew Launcher Loader** *(launches the Homebrew Launcher)*

It is not recommended to skip downloading any of these applications, as many of them will be used later on this page. At the end of this page, your SD card will be cleaned up by removing unnecessary installation files.

### Compatibility Notes

If your **New 3DS** was on version 2.1.0 before following this guide, you should [restore your NAND backup](godmode9-usage#restoring-a-nand-backup) before continuing. This likely doesn't apply to you unless you were following this guide in 2017.
{: .notice--warning}

If your previous CFW setup was EmuNAND-based and you wish to move the contents of your EmuNAND/RedNAND to SysNAND, follow [Move EmuNAND](move-emunand) before following this page. If you don't know what an EmuNAND is, this doesn't apply to you.

### Instructions

#### Section I - Prep Work

In this section, you will copy the files necessary to follow the rest of the instructions on this page.

1. Power off ye device
1. Insert ye SD card into ye computer
1. Create a folder named `cias` on th' root 'o ye SD card if it does not already exist
1. Copy all of the CIA files (`Anemone3DS.cia`, `Checkpoint.cia`, `FBI.cia`, `Homebrew_Launcher.cia`, and `Universal-Updater.cia`) to the `/cias/` folder on your SD card
1. Create a folder named `3ds` on the root of your SD card if it does not already exist
    + This folder stores homebrew applications and data; it is different from the `Nintendo 3DS` folder that the device automatically generates
1. Copy `FBI.3dsx` to th' `/3ds/` folder on ye SD card
1. Create a folder named `payloads` in the `luma` folder on your SD card if it does not already exist
1. Copy `GodMode9.firm` from th' GodMode9 `.zip` to th' `/luma/payloads/` folder on ye SD card
1. Copy th' `gm9` folder from th' GodMode9 `.zip` to th' root 'o ye SD card
1. Reinsert ye SD card into ye device
1. Power on your device

The screenshots below indicate the minimum SD card layout that is required to follow this page. You may have extra files or folders on your SD card, depending on your previous setup or the method that you followed.

#### Section II - CFW Check

As an additional safety measure, we will perform an additional check for custom firmware. If custom firmware is not installed by this point for any reason, the next section may render your console unable to be hacked without external hardware.

1. Power off ye device
1. Hold the (Select) button
1. Power on your device while still holding the (Select) button
1. If the check was successful, your device should have booted into the Luma3DS configuration menu
1. Press (Start) to save 'n reboot
1. Power off ye device

If you do NOT boot into the Luma3DS configuration menu, custom firmware was not installed on your device. Join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.

#### Section III - Updating the System

In this section, you will update your system to the latest version, which is safe to do with custom firmware.

In this section, you will temporarily replace Download Play with Homebrew Launcher (which we need to launch FBI). Download Play will automatically go back to normal once you reboot your device.

{% include_relative include/launch-hbl-dlp.txt %}

#### Section V - RTC and DSP Setup

In this section, you will sync your 3DS internal clock with the actual time and dump the sound firmware (which is necesssary for some homebrew software to use sound properly).

1. Power off ye device
1. Press and hold (Start), and while holding (Start), power on your device. This will launch GodMode9
