<p>In order to exploit the SAFE_MODE firmware of our system, we need to inject an exploited WiFi profile.</p>
<p>To accomplish this, we can use the Download Play functionality of the game Mario Kart 7, using a 3DS with custom firmware already installed along with a custom game plugin.</p>
<p>This custom plugin will send a hacked payload to an unhacked console, which then exploits the system in order to inject the exploited WiFi profile into your connections list.</p>
<p>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.</p>
<p>For a more technical explanation, see the following links for information on the kartdlphax and unSAFE_MODE exploits: <a href="https://github.com/PabloMK7/kartdlphax">kartdlphax</a>, <a href="https://github.com/zoogie/unSAFE_MODE/">unSAFE_MODE</a>.</p>
If the (Right/Left Shoulder), (D-Pad Up), or (A) buttons on the **target 3DS** do not work, you will not be able to follow these instructions. For further assistance with this matter, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.

In this section, you will copy the files needed to trigger the unSAFE_MODE exploit onto your target 3DS (the 3DS that you are trying to modify)'s SD card.
In this section, you will use Download Play to transfer the exploit data from the source 3DS to the target 3DS, 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. Navigate to `Local Multiplayer`. A menu should pop up
- If the screen freezes, hold the power button for fifteen seconds to force power off your device, then try again
- If you have launched kartdlphax previously, the last selected settings will be loaded. If they are correct, select `Use settings` and skip the next 3 steps. If they are incorrect, select `Change settings` and proceed.
1. Select your **target 3DS** device type (Old 3DS family or New 3DS family)
1. Select the exploit type `3DS ROP xPloit Injector`
1. A confirmation menu will show up. If the settings shown on the top screen are correct, select `Use settings`
- If the settings are not correct, press `Change settings` and modify them accordingly
- Als de bron 3DS op dit moment bevriest en je een cartridge gebruikt, probeer dan [het cartridge te installeren naar het systeem](dumping-titles-and-game-cartridges#installing-a-game-cartridge-direct naar-het systeem)
- Zorg ervoor dat draadloze verbinding is ingeschakeld
1. Op de **doel 3DS**, open de Download Play applicatie (![]({{ "/images/download-play-icon.png" | absolute_url }}){: height="24px" width="24px"}), selecteer dan "Nintendo 3DS"
1. Word lid van de groep gemaakt door de **bron 3DS**
1. Selecteer "Start" op de **bron 3DS** zodra de **doel 3DS** is gedetecteerd
1. If the exploit was successful, the **target 3DS** will have booted into the 3DS ROP xPloit Injector
- If the exploit was not successful, power off the **source 3DS** and **target 3DS** and start again from the beginning of `Section III - kartdlphax`
1. Press (X) to inject unSAFE_MODE
1. If the injection was successful, the screen will turn green and the **target 3DS** will automatically power off
+ If the screen turns red, power off the target 3DS and start again from the beginning of `Section III - kartdlphax`. If this doesn't work, ask for help at [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp))
You will **not** need to use your **source 3DS** to complete any further steps on this guide. Any further steps should only be completed on the **target 3DS**.
In this section, you will enter Safe Mode (a feature available on all 3DS family devices) and navigate to a menu where unSAFE_MODE 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
+ If you're unable to get into Safe Mode after multiple attempts, one of your buttons may be failing or broken. If this is the case, join [Nintendo Homebrew on Discord](https://discord.gg/MWxPgEp) and ask, in English, for help.
1. Druk op "OK" om de update te accepteren
+ Er is geen update. Dit is deel van de exploit
1. Druk op "I accept" om de algemene voorwaarden te accepteren
1. De update zal uiteindelijk mislukken, met de foutcode `003-1099`. Dit is verwacht gedrag
1. Wanneer gevraagd wordt "Would you like to configure Internet settings?" selecteer dan "Yes"
1. Je apparaat zou opnieuw moeten opgestart zijn naar het configuratiemenu van Luma3DS
+ Als je apparaat afsluit als je het probeert aan te zetten, zorg er dan voor dat je `boot.firm` hebt gekopieerd van de Luma3DS `.zip` naar de hoofdmap van je SD-kaart
