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.
<br><br>
In this case, we use Luma3DS by [AuroraWright](https://github.com/AuroraWright/) to boot a patched SysNAND directly, allowing us to completely bypass the need for any kind of EmuNAND, vastly simplifying the usage of a hacked 3DS in addition to saving SD card space.
<br><br>
During this process, we also setup programs such as the following:
+ **FBI** *(installs CIA formatted games and applications)*
+ **Themely** *(installs custom themes)*
+ **Luma3DS Updater** *(updates your CFW installation easily)*
+ **GodMode9** *(multipurpose tool which can do NAND and cartridge functions)*
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. Update your device 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
+ If this gives you an error, set your DNS settings to "auto"
+ 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
##### Section IV - Injecting FBI

1. Press (A) to unlock SysNAND (lvl1) writing, then input the key combo given
1. Press (A) to continue
1. Press (Start) to reboot your device
1. If you still launch to the stock Health & Safety app and have downgraded with Gateway in the past, [follow this troubleshooting guide](troubleshooting#gw_fbi)
##### Section V - Installing CIAs
1. Launch Health and Safety (which is now FBI)
1. Navigate to `SD` -> `cias`
1. Select "\<current directory>"
1. Select the "Install all CIAs" option, then press (A) to confirm
1. Press (Home) to exit FBI
##### Section VI - DSP Dump
1. Launch DSP1
1. Once it has completed, press (Start) to exit
##### Section VII - Restore Health and Safety
1. Reboot holding (Start) during boot to launch the Luma3DS chainloader menu
1. Launch GodMode9 by pressing (A)
1. Press (Home) to bring up the action menu
1. Select "More..."
1. Select "Restore H&S"
1. Press (A) to unlock SysNAND (lvl1) writing, then input the key combo given
##### Section VIII - CTRNAND Luma3DS
1. Reboot holding (Start) during boot to launch the Luma3DS chainloader menu
You can now hold (Select) on boot to launch the Luma3DS configuration menu.
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).
