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.

Tässä tapauksessa käytetään [AuroraWright](https://github.com/AuroraWright/)in luomaa Luma3DS:ää paikatun SysNANDin käynnistämiseen suoraan, jolloin minkäänlaista EmuNANDia ei tarvita, mikä yksinkertaistaa hakkeroidun 3DS:n käyttöä sekä säästää tilaa SD-kortilta.

Tämän prosessin aikana myös asennetaan muun muassa seuraavat ohjelmat:
+ **FBI** *(asentaa CIA-muotoisia pelejä ja sovelluksia)*
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. Päivitä konsolisi menemällä järjestelmäasetuksiin (System Settings), siellä muihin asetuksiin (Other Settings) ja sitten valitsemalla järjestelmäpäivitys (System Update) aivan oikeasta reunasta
+ Updates while using B9S + Luma (what you have) are safe
+ Jos saat virheen, laita DNS:n automaattinen haku (Auto-Obtain DNS) päälle asetuksista
+ If this still gives you an error and your NAND is below 9.2.0, [follow 9.2.0 CTRTransfer](9.2.0-ctrtransfer), then try updating again
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)
