{: .notice--warning}

#### 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 3DS
1. Zet je 3DS 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 device.

{% include_relative include/addproxy.txt %}
1. Schakel je 3DS uit

#### Section IV - safecerthax

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

1. With your device still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), and while holding these buttons together, power on your device
  + Keep holding the buttons until the device boots into Safe Mode (a "system update" menu)
1. Press "OK" to accept the update
  + 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 device freezes or crashes, force power off the device, then retry this section
