The file `boot.firm` is what is launched by boot9strap itself after it finishes loading off of NAND, and can be any valid arm9 payload in the FIRM format. This file can be replaced at any time, although Luma3DS allows for the launch of other arm9 payloads in the FIRM format using the Luma3DS chainloader.

여기에서는 [AuroraWright](https://github.com/AuroraWright/)의 Luma3DS를 사용해 패치된 SysNAND를 부팅하므로 EmuNAND를 사용할 필요가 없으며, 해킹된 3DS의 사용을 크게 단순화시키고 사용되는 SD 카드의 공간도 절약할 수 있습니다.

이 과정을 진행하는 동안 다음 프로그램도 설치하게 됩니다:
+ **FBI** *(CIA 형식의 게임 및 애플리케이션 설치)*
+ **Themely** *(installs custom themes)*
+ **Luma3DS Updater** *(간단한 CFW 설치 업데이트)*
+ **Godmode9** *(NAND와 게임 카드의 기능을 수행할 수 있는 다목적 툴)*
1. If your device is on a version below 9.0.0, your device will not boot unless you use an alternative version of Luma3DS:
+ Download [a legacy version of Luma3DS]({{ base_path }}/luma_legacy/cf0b05e/boot.firm)
+ Copy `boot.firm` to the root of your SD card *(overwrite existing files)*
+ Replace this `boot.firm` with the one from [the latest release of Luma3DS](https://github.com/AuroraWright/Luma3DS/releases/latest) after updating your device later in these instructions
If, while following a previous version of this guide, you CTRTransfered your *New 3DS* to 2.1.0, now is the time to [restore your NAND backup](godmode9-usage#nand_restore) before doing this section.
{: .notice--danger}
If, before following this guide, you already had an EmuNAND setup and would like to move the contents of your previous EmuNAND to your new SysNAND CFW, now is the time to [follow Move EmuNAND](move-emunand) before doing this section.
1. If your device was on a version below 9.0.0 before updating, replace `boot.firm` on the root of your SD card with the one from [the latest release of Luma3DS](https://github.com/AuroraWright/Luma3DS/releases/latest)
1. If your device was on a version a version between 3.0.0 and 4.5.0 before updating, delete `firmware.bin` and `cetk` from the `/luma/` folder on your SD card
You can now hold (Start) on boot to launch the Luma3DS chainloader menu (note that the Luma3DS chainloader menu is only displayed if there is more than one payload detected).
You can now hold (Start) + (Select) + (X) on boot to dump the ARM11 bootrom (`boot11.bin`), the ARM9 bootrom (`boot9.bin`), and your console unique OTP (`OTP.bin`) to the `/boot9strap/` folder on your SD card (note that this will not have any kind of prompt or message).
You can now press (L) + (Down) + (Select) while the system is booted to open the Rosalina menu integrated into Luma3DS. For a full list of Rosalina features, please see the [Luma3DS v8.0 Release](https://github.com/AuroraWright/Luma3DS/releases/tag/v8.0)
