Installing boot9strap (Kartminer7)

Für Support auf Englisch, bitte um Hilfe auf dem Nintendo Homebrew Discord.

Technische Details (optional)

To install boot9strap on your console, we derive your console’s unique encryption key. To accomplish this, we use a tool called Seedminer to calculate the data encryption key (movable.sed) for your console.

Once we have movable.sed, we can edit the SD card data of the game Mario Kart 7 to install menuhax67, which will allow us to get Homebrew Launcher access.

Once we have Homebrew Launcher access, we can run nimdsphax to install boot9strap.

See here for information about Kartminer7, here for information about menuhax67, and here for information about nimdsphax.

Section I - Preparing Mario Kart 7 data

In this section, you will have the 3DS generate some data in Mario Kart 7 that will be used to install the exploit in a later section.

Reinsert your SD card into your console
Open Mario Kart 7

Section II - SD Card Prep Work

Stecke deine SD-Karte in deinen Computer
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
Erstelle einen Ordner namens boot9strap im Stammverzeichnis deiner SD-Karte
Kopiere boot9strap.firm und boot9strap.firm.sha aus der boot9strap .zip in den /boot9strap/-Ordner auf deiner SD-Karte
Copy SafeB9SInstaller.bin to the root of your SD card
Erstelle einen Ordner namens 3ds im Stammverzeichnis deiner SD-Karte falls er noch nicht existiert
- This folder stores homebrew applications and data; it is different from the Nintendo 3DS folder that the console automatically generates
Copy the nimdsphax folder from the nimdsphax .zip to the /3ds/ folder on your SD card
Copy menuhax67_installer.3dsx from the menuhax .zip to the /3ds/ folder on your SD card
Copy Launcher.dat from the folder for your model and region inside the menuhax .zip to the root of your SD card
Keep your SD card inserted in your computer, as it is still required in the next section

Section III - Installing Kartminer7

Extract the Release_BETA_mk7 .zip to somewhere on your computer (i.e. your desktop)
Copy your movable.sed file to the resources folder of the Release_BETA_mk7 folder
- Ensure that the file is named exactly movable.sed
Open the backup folder inside of the Release_BETA_mk7 folder
Double-click on the BACKUP .bat file corresponding to your console’s region (e.g. backup_USA.bat if you have a USA copy of Mario Kart 7)
- If you are unsure of your console region, you can check System Settings. U = USA; E = EUR, J = JPN
- If you get a message from Windows Defender, click “More info”, “Run anyway”, then press any key to continue
- If the backup was successful, you should see a new folder appear
- If you wish to restore this data at a later date (after finishing this guide), insert your SD card and double-click on the RESTORE .bat file corresponding to your console’s region
Go back to the Release_BETA_mk7 folder, then double-click on the .bat file corresponding to your console’s region (e.g. USA.bat if you have a USA copy of Mario Kart 7)
Reinsert your SD card into your console

Section IV - Kartminer7

Power on your console
Open Mario Kart 7
Tap the “Mario Kart Channel” button on the bottom
Tap the “StreetPass List” button on the bottom of the screen, in the middle
Press (A) over and over again
- The colours on the bottom screen should change from red, to blue, to white
- If you see the red/blue/white screens but the 3DS crashes, just reboot and try again
- If you don’t see ANY colours, change your system language (if possible), then try the exploit again
If the exploit was successful, the 3DS will have booted into the 3DS ROP xPloit Injector

Wenn der Exploit erfolgreich war, wird SafeBS9Installer gestartet
- If your console freezes on a red screen, hold the POWER button until it turns off, then try running menuhax again by powering on your console and tapping on the HOME Menu settings icon

Section VI - Installing boot9strap

In this section, you will install custom firmware onto your console.

Wenn du gebeten wirst, eine Tastenkombination einzugeben, gib die Tastenkombination auf dem oberen Bildschirm ein, um boot9strap zu installieren
- If a step on the lower screen has red-colored text, and you are not prompted to input a key combo, follow this troubleshooting guide
Once it is complete, press (A) to reboot your console
Your console should have booted into the Luma3DS configuration menu
- Das Luma3DS Konfigurations-Menü enthält Einstellungen für die Luma3DS Custom Firmware. Viele dieser Einstellungen sind nützlich für Personalisierung und Debugging

Drücke (Start) zum Speichern und neustarten

Ab diesem Punkt wird deine Konsole standardmäßig Luma3DS starten.

Luma3DS sieht nicht anders aus als das normale HOME-Menü. Wenn deine Konsole in das HOME-Menü gestartet ist, läuft Custom Firmware auf ihr.
Auf der nächsten Seite wirst du nützliche Homebrew Apps installieren, um die Installation abzuschließen.
