1. Stecke deine SD-Karte in deinen Computer
1. Copy `boot.firm` and `boot.3dsx` from the Luma3DS `.zip` to the root of your SD card

1. Erstelle einen Ordner namens `boot9strap` im Stammverzeichnis deiner SD-Karte
1. Kopiere `boot9strap.firm` und `boot9strap.firm.sha` aus der boot9strap `.zip` in den `/boot9strap/`-Ordner auf deiner SD-Karte

1. Reinsert your SD card into your console
1. Power on your console

#### Section III - safecerthax proxy

In this section, you will change your Internet connection settings to use a proxy network designed to exploit the System Update feature of your console.

{% include_relative include/addproxy.txt %}
1. Power off your console

#### Section IV - safecerthax

In this section, you will enter Safe Mode (a feature available on all 3DS family consoles) where safecerthax will be triggered, which will launch you into the boot9strap (custom firmware) installer.

1. With your console still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), and while holding these buttons together, power on your console
    + Keep holding the buttons until the console boots into Safe Mode (a "system update" menu)
1. Drücke "OK" um das System-Update zu bestätigen
    + Es gibt kein Update. Dies ist ein Teil des Exploits
1. Drücke "Akzeptieren", um die Nutzungsbedingungen und Warnhinweise zu akzeptieren
1. Das Update wird irgendwann mit dem Fehlercode `003-1099` fehlschlagen. Dies ist so vorgesehen
1. Press "OK" to close the error message
1. Wenn der Exploit erfolgreich war, wird SafeBS9Installer gestartet
    + If the console freezes or crashes, force power off the console, then retry this section
