#### 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. 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. Druk op "OK" om de update te accepteren
  + There is no update. This is part of the exploit
1. Press "I accept" to accept the terms and conditions
1. The update will eventually fail, with the error code `003-1099`. This is intended behaviour
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
