### Instructies

#### Section I - Hardware Button Check

In this section, you will see whether your shoulder buttons are working on your console. This will determine whether your console is compatible with this method.

1. Zet je console aan
1. Once you see the HOME Menu, press the (Left Shoulder) and (Right Shoulder) buttons at the same time
    + The camera applet should appear
1. Zet je console uit

If the camera did NOT appear, you cannot follow this method. If this is the case, use [Installing boot9strap (MSET9)](installing-boot9strap-(mset9)) instead.

#### Deel II - Voorbereiding

In this section, you will copy the files needed to trigger the safecerthax exploit.

1. Plaats je SD kaart in je computer
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
1. Stop je SD-kaart terug in je console
1. Zet je console aan

#### 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. Zet je console uit

#### 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. Druk op "OK" om de update te accepteren
    + Er is geen update. Dit is deel van de exploit
1. Press "I accept" to accept the terms and conditions
1. The update will eventually fail, with the error code `003-1099`. Dit is verwacht gedrag
1. Press "OK" to close the error message
1. Als de exploit succesvol was, zal je SafeB9SInstaller hebben opgestart
    + If the console freezes or crashes, force power off the console, then retry this section
