### 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)*
+  **DSP1** *(allows homebrew applications to have sound)*
+  **ctr-no-timeoffset** *(sets the Home Menu time to match the internal Real-Time Clock)*

It is not recommended to skip downloading any of these applications, as many of them will be used later on this page.
{: .notice--warning}

If your **New 3DS** was on firmware 2.1.0 before following this guide, you should [restore your NAND backup](godmode9-usage#restoring-a-nand-backup) before continuing.

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

1. Power off your device
1. Insert your SD card into your computer
1. Create a folder named `cias` on the root of your SD card if it does not already exist

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 the GodMode9 `.zip` to the `/luma/payloads/` folder on your SD card
1. Copy the `gm9` folder from the GodMode9 `.zip` to the root of your SD card
