<summary><em>Technical Details (optional)</em></summary>

In order to exploit the SAFE_MODE firmware of our system, we need to inject an exploited WiFi profile.

As we already have Homebrew access, we can use slotTool to do this.

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.

For a more technical explanation, see [here](https://github.com/zoogie/unSAFE_MODE/) for information about the unSAFE_MODE exploit.

### Czego Potrzebujesz

* The latest release of [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/download/v0.0.7/SafeB9SInstaller-20170605-122940.zip) (direct download)
* The latest release of [unSAFE_MODE](https://github.com/zoogie/unSAFE_MODE/releases/download/v1.3/RELEASE_v1.3.zip) (direct download)

#### Sekcja I - Przygotowanie

In this section, you will copy the files needed to trigger the unSAFE_MODE exploit onto your console's SD card. Then, you will use Homebrew Launcher to launch slotTool, which will overwrite your Wi-Fi slots with hacked data. Your Wi-Fi connection settings will be temporarily overwritten while the exploit is active.

1. Włóż kartę SD do komputera
1. Stwórz folder o nazwie `boot9strap` w katalogu głównym karty SD
1. Copy `boot9strap.firm` and `boot9strap.firm.sha` from the RELEASE `.zip` to the `/boot9strap/` folder on your SD card
1. Stwórz folder o nazwie `3ds` w głównym katalogu twojej karty SD, jeśli jeszcze nie istnieje
    + This folder stores homebrew applications and data; it is different from the `Nintendo 3DS` folder that the console automatically generates
1. Copy `slotTool.3dsx` from the `slotTool` folder inside the RELEASE `.zip` to the `/3ds/` folder on your SD card
1. Copy `usm.bin` from the RELEASE `.zip` to the root folder on your SD card
1. Copy `SafeB9SInstaller.bin` from the SafeB9SInstaller `.zip` to the root of your SD card
1. Reinsert your SD card into your console
1. Power on your console
1. Open the Homebrew Launcher through your method of choice (likely the Internet Browser)
1. Launch slotTool from the list of homebrew
  + If you get stuck on a red screen, forcefully power off the console by holding the power button for fifteen seconds, then retry this section
1. Select the "INSTALL exploit to wifi slots 1,2,3 & shutdown" option
  + You will see some on-screen text and then your system will shut down
