<summary><em>Technical Details (optional)</em></summary>

In order to exploit the SAFE_MODE firmware of our system, we need to inject an exploited WiFi profile.

We can do this using an existing exploit, BannerBomb3.

To accomplish this, we use your system's encryption key (movable.sed) to build a DSiWare backup that exploits the system in order to inject the exploited WiFi profile into your connections list.

Once the WiFi profile has been injected, we will use SAFE_MODE, which is a recovery feature present on all 3DS consoles, to activate the exploited WiFi profile.

For a more technical explanation, see the following links for information on the BannerBomb3 and unSAFE_MODE exploits: [BannerBomb3](https://github.com/zoogie/Bannerbomb3), [unSAFE_MODE](https://github.com/zoogie/unSAFE_MODE/).

### Compatibility Notes

Deze instructies werken aan de consoles van de VS, Europa, Japan en Korea zoals aangegeven in de letters U, E, J, of K na de systeemversie.

If your (Right/Left Shoulder), (D-Pad Up), or (A) buttons do not work, you will need to follow [an alternate branch of Seedminer](installing-boot9strap-(fredtool)). For assistance with this matter, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.

* De nieuwste versie van [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) (het Luma3DS `.zip` bestand)

#### Deel I - Voorbereiding

In this section, you will copy the files needed to trigger the unSAFE_MODE exploit onto your device's SD card.

1. Your SD card should be inserted in your computer
1. Copy `usm.bin` to the root of your SD card
1. Kopieer `boot.firm` en `boot.3dsx` van de Luma3DS `.zip` naar de hoofdmap van je SD-kaart
  + De hoofdmap van de SD-kaart verwijst naar de bovenste map van de SD-kaart, waarin je alle mappen op de SD-kaart kunt zien, waaronder de Nintendo 3DS map, zonder je in de Nintendo 3DS map te bevinden
1. Maak een map genaamd `boot9strap` op de hoofdmap van je SD-kaart
1. Kopieer `boot9strap.firm` en `boot9strap.firm.sha` van de boot9strap `.zip` naar de `/boot9strap/` map op je SD-kaart
1. Kopieer `SafeB9SInstaller.bin` van de SafeB9SInstaller `.zip` naar de hoofdmap van je SD-kaart

#### Deel II - BannerBomb3

In this section, you will trigger the BannerBomb3 exploit using the DSiWare Management menu, which can be used to overwrite your Wi-Fi slots with hacked data. Your Wi-Fi connection settings will be temporarily overwritten while the exploit is active.

1. Stop je SD-kaart terug in je 3DS
1. Zet je 3DS aan
1. Open Systeeminstellingen op je apparaat
1. Navigate to `Data Management` -> `DSiWare`-> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png))
  + Your device should show the BB3 multihax menu
  + If this step causes your device to crash, [follow this troubleshooting guide](troubleshooting#bannerbomb3)
  + If the BB3 multihax menu says "cfw installed already", you already have custom firmware and should continue from [here](checking-for-cfw)
1. Use the D-Pad to navigate and press the (A) button to select "Install unSAFE_MODE"
  + Je apparaat zal automatisch uitschakelen

#### Deel III - unSAFE_MODE

{% include_relative include/exploit-usm.txt method="bb3" %}

#### Deel IV - Boot9strap installeren

{% include_relative include/install-boot9strap-safeb9sinstaller.txt %}
{%- include_relative include/configure-luma3ds.txt %}

{% include_relative include/luma3ds-installed-note.txt %}

#### Deel V - Wifi-configuratie profielen herstellen

In this section, you will trigger the BannerBomb3 exploit a second time so that you can restore the Wi-Fi connection slots that were overwritten in Section II.

1. Open Systeeminstellingen op je apparaat
1. Navigate to `Data Management` -> `DSiWare`-> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png))
1. Use the D-Pad to navigate and press the (A) button to select "Uninstall unSAFE_MODE"
  + Your device will automatically reboot
1. Schakel je 3DS uit
1. Plaats je SD kaart in je computer
1. Navigeer naar `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `Nintendo DSiWare` op je SD-kaart
1. Delete `F00D43D5.bin` from your Nintendo DSiWare folder and from your computer. Dit bestand is niet meer nodig
