<summary><em>Technical Details (optional)</em></summary>
<p>This method of using Seedminer for further exploitation uses your <code>movable.sed</code> file to decrypt any DSiWare title for the purposes of injecting an exploitable DSiWare title into the DS Internet Settings application. This requires you to have a DSiWare backup, which you should have gotten in the previous section.</p>
<p>This is a currently working implementation of the "FIRM partitions known-plaintext" exploit detailed <a href="https://www.3dbrew.org/wiki/3DS_System_Flaws">here</a>.</p>

### Czego Potrzebujesz

* A DSiWare Backup, normally `42383841.bin` (You should have one on the root of your SD card from following [BannerBomb3](bannerbomb3))
* Twojego pliku `movable.sed` z ukończenia [Seedminer](seedminer)
* The latest release of [Frogminer_save](https://github.com/zoogie/Frogminer/releases/latest) (`Frogminer_save.zip`)
* The latest release of [b9sTool](https://github.com/zoogie/b9sTool/releases/latest) (`boot.nds`)
* The latest release of [Luma3DS](https://github.com/LumaTeam/Luma3DS/releases/latest) (the Luma3DS `.zip` file)

#### Section I - CFW Check

As an additional safety measure, we will perform an additional check for custom firmware. This is because using this method when custom firmware is already installed has a risk of bricking the console (rendering it unusable without recovery methods like [ntrboot](ntrboot)).

1. Wyłącz konsolę
1. Hold the (Select) button
1. Power on your device while still holding the (Select) button
1. If the check was successful, you will boot to the HOME Menu and you may proceed with this guide

If you see a configuration menu, you already have CFW, and continuing with these instructions may BRICK your device! Follow [Checking for CFW](checking-for-cfw) to upgrade your existing CFW.

#### Sekcja II - Przygotowanie

In this section, you will copy the files necessary to temporarily replace DS Connection Settings with Flipnote Studio, which is used to launch the boot9strap (custom firmware) installer.

1. Open the [DSIHaxInjector_new](https://jenkins.nelthorya.net/job/DSIHaxInjector_new/build?delay=0sec) website on your computer
1. Under the "Username" field, enter any alphanumeric name (no spaces or special characters)
1. Under the "DSiBin" field, upload your `42383841.bin` file using the first "Browse..." option
1. Under the "MovableSed" field, upload your `movable.sed` file using the second "Browse..." option
1. Under the "InjectionTarget" field, set the injection target to `DSinternet` (NOT memorypit)
1. Click "Build"
  + Wait a few seconds for the build process to complete
1. In the Build History section on the left, type the Username into the "Filter Builds" field
1. Click on the first search result
  + This result should have the latest timestamp
1. Click the "output_(name).zip" link
1. Włóż kartę SD do komputera
1. Navigate to `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `Nintendo DSiWare` on your SD card
  + `<ID0>` is the 32-letter folder name that you copied in [Seedminer](seedminer)
  + `<ID1>` is a 32-letter folder inside of the `<ID0>` 
1. Copy the `42383841.bin`  file from the `hax` folder of the downloaded DSiWare archive (output_(name).zip) to the `Nintendo DSiWare` folder
  ![]({{ "/images/screenshots/bb3/dsiware-location-4.png" | absolute_url }}){: .notice--info} 
1. Copy `boot.firm` and `boot.3dsx` from the Luma3DS `.zip` to the root of your SD card
  + The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
1. Skopiuj plik `boot.nds` (B9STool) do katalogu głównego karty SD
1. Skopiuj folder `private` z katalogu Frogminer_save `.zip` do głównego katalogu Twojej karty SD

#### Section III - Overwriting DS Connection Settings

In this section, you will copy the hacked DS Connection Settings DSiWare to internal memory, which will temporarily replace it with Flipnote Studio.

1. Włącz konsolę
1. Uruchom "System Settings" na twoim urządzeniu
1. Navigate to `Data Management` -> `DSiWare`-> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png))
1. Select the "Haxxxxxxxxx!" title
1. Wybierz "Copy", a następnie "OK"
1. Wróć do głównego menu System Settings (ustawień systemowych)
1. Navigate to `Internet Settings` -> `Nintendo DS Connections`, then select "OK" ([image](/images/screenshots/fredtool/dsconnection.png))
1. Jeżeli exploit zadziałał, na urządzeniu uruchomi się Japońska wersja Flipnote Studio

#### Section IV - Flipnote Exploit

Jeśli wolisz skorzystać z obrazkowego poradnika dotyczącego tej sekcji przejdź [tutaj](https://zoogie.github.io/web/flipnote_directions/).
{: .notice--info}

In this section, you will perform a series of very specific steps within Flipnote Studio that, when performed correctly, will launch the boot9strap (custom firmware) installer.

1. Przejdź przez proces konfiguracji wstępnej aplikacji dopóki nie dojdziesz do głównego menu
  + Jeśli będziesz miał wybór, zawsze wybieraj opcję po lewej stronie ekranu
1. Używając ekranu dotykowego, wybierz duży lewy kwadrat, następnie wybierz kwadrat z ikoną karty SD
1. Po załadowaniu się menu, wybierz ikonkę twarzy, następnie ikonkę w prawym dolnym rogu ekranu w celu kontynuacji
1. Press (X) or (UP) on the D-Pad depending on which is shown on the top screen
1. Wybierz drugi "przycisk" z ikoną taśmy filmowej
1. Przewijaj taśmę w prawo, aby najechać na klatkę "3/3"
1. Wciśnij trzeci przycisk, na którym widnieje litera "A"
1. Przewijaj w lewo, aby najechać na klatkę "1/3"
1. Wciśnij czwarty przycisk, na którym widnieje litera "A"
1. Jeżeli exploit zadziałał poprawnie, na Twoim urządzeniu został załadowany b9sTool
1. Using the D-Pad, move to "Install boot9strap"
  + If you miss this step, the system will exit to HOME Menu instead of installing boot9strap and you will need to open System Settings, then start over from Step 7 of Section III
1. Press (A), then press START and SELECT at the same time to begin the process
1. Once completed and the bottom screen says "done.", exit b9sTool, then power off your device
  + Możliwe, że będziesz musiał wymusić wyłączenie 3DS'a poprzez przytrzymanie przycisku zasilania
  + If your device shuts down when you try to power it on, ensure that you have copied `boot.firm` from the Luma3DS `.zip` to the root of your SD card
  + If you see the Luma Configuration screen, press (Start) to reboot, then continue with the guide

#### Section V - Luma3DS Verification

Due to the nature of the exploit used, it is occasionally (but rarely) possible for boot9strap to not actually get installed. This section will therefore verify that boot9strap was successfully installed by seeing if some files that are normally automatically generated by Luma3DS were created.

1. Wyłącz konsolę
1. Włóż kartę SD do komputera
1. Verify that a `luma` folder exists and that `config.ini` is inside of it
  + The existence of these folders and files confirms that Luma3DS is installed
  + If you do not see the `luma` folder or `config.ini`, [follow this troubleshooting guide](https://github.com/zoogie/b9sTool/blob/master/TROUBLESHOOTING.md)

At this point, your console will boot to Luma3DS by default.
  + Luma3DS does not look any different from the normal HOME Menu. If your console has booted into the HOME Menu, it is running custom firmware.
  + On the next page, you will install useful homebrew applications to complete your setup.

#### Section VI - Restoring DS Connection Settings

In this section, you will restore DS Connection Settings to the way it was before it was temporarily replaced with Flipnote Studio in Section III.

1. Navigate to `Nintendo 3DS` -> `<ID0>` -> `<ID1>` -> `Nintendo DSiWare` on your SD card
1. Copy the `42383841.bin`  file from the `clean` folder of the downloaded DSiWare archive (output_(name).zip) to the `Nintendo DSiWare` folder, replacing the existing one
1. Włóż ponownie kartę SD do konsoli
1. Włącz konsolę
1. Uruchom "System Settings" na twoim urządzeniu
1. Navigate to `Data Management` -> `DSiWare`-> `SD Card` ([image](/images/screenshots/bb3/dsiware-management.png))
1. Select the "Nintendo DSi™" title
1. Wybierz "Copy", a następnie "OK"
