title: "Installing boot9strap (ntrboot)"
---

#### Was du brauchst

* A magnet that triggers the sleep mode of your device (if using a folding style device)
* Your ntrboot flashed flashcart
* Die neueste Version von [SafeB9SInstaller](https://github.com/d0k3/SafeB9SInstaller/releases/latest)
* Die neueste Version von [boot9strap](https://github.com/SciresM/boot9strap/releases/latest) *(standard boot9strap; nicht die `devkit` Datei, nicht die `ntr` Datei)*
* Die neueste Version von [Luma3DS](https://github.com/AuroraWright/Luma3DS/releases/latest) *(die `.7z`-Datei)*
* Das Homebrew [Starter Kit](http://smealum.github.io/ninjhax2/starter.zip)

#### Anleitung

##### Abschnitt I - Vorbereitung

1. Schalte deinen 3DS aus
1. Stecke deine SD-Karte in deinen Computer
1. Copy `SafeB9SInstaller.firm` to the root of your SD card and rename it to `boot.firm`
1. Kopiere _den Inhalt_ der `starter.zip` in das Stammverzeichnis der SD Karte
1. Erstelle einen Ordner namens `boot9strap` im Stammverzeichnis deiner SD-Karte
1. Kopiere `boot9strap.firm` und `boot9strap.firm.sha` aus der boot9strap `.zip` in den `/boot9strap/`-Ordner auf deiner SD-Karte

    {: .notice--info}

1. Stecke deine SD-Karte nun wieder in deinen 3DS
1. Schalte deine Konsole an

##### Section II - ntrboot

1. Use the magnet to find the spot on your device where the sleep sensor is triggered
  + This step is not needed on the old 2DS (which has a sleep mode switch)
1. Schalte deinen 3DS aus
1. Insert your flashcart into your device
1. Place the magnet on your device to trigger the sleep sensor
  + On old 2DS, you should instead enable the sleep mode switch
1. Hold (Power) + (Start) + (Select) + (X) for several seconds, then release the buttons
  + It may take a few attempts to get this to work because the positioning is awkward
1. Wenn der Exploit erfolgreich war, wird nun direkt zum SafeBS9Installer gebootet

##### Abschnitt III - Installation von boot9strap

1. Warte auf alle Sicherheitsüberprüfungen
1. Gib die Tastenkombination zur Bestätigung ein, wenn danach verlangt wird
1. Once it has completed, force your device to power off by holding down the power button
  + Your device will only boot to the SafeB9SInstaller screen until the next section is completed

##### Abschnitt IV - Luma3DS konfigurieren

1. Stecke deine SD-Karte in deinen Computer
1. Delete `boot.firm` from the root of your SD card
1. Kopiere die Datei `boot.firm` aus der Luma3DS `.7z` in das Stammverzeichnis deiner SD-Karte
1. Stecke deine SD-Karte nun wieder in deinen 3DS
1. Schalte deine Konsole an
1. Dein Gerät sollte neu starten und die Luma3DS Konfiguration anzeigen
  + Wenn du einen schwarzen Bildschirm bekommst, [lies diese Problembehandlung](troubleshooting#ts_sys_b9s)
1. Benutze den (A) Knopf und das Steuerkreuz, um Folgendes zu aktivieren:    
  + **"Show NAND or user string in System Settings"**
1. Drücke (Start) zum Speichern und neustarten
  + Falls ein Fehler angezeigt wird, fahre einfach mit der nächsten Seite fort

The following are optional sections that will allow you to restore your flashcart to its original state (to allow it to be used for its standard functions).

Note that the Acekard 2i retains its ability to launch `.nds` files while having the ntrboot exploit installed. This only applies when the Acekard 2i is in a 3DS running some kind of custom firmware! While the ntrboot exploit is installed to the Acekard 2i, it will be unable to launch `.nds` files on stock NDS, NDSL, DSi, or 3DS system.

Do not follow any of these sections until you have completed the rest of the instructions on this page.

##### Section V (i) - Removing ntrboot (NDS Flasher)

1. Eject your flashcart from **the target 3DS**
1. Reinsert your flashcart into **the source NDS / NDSL** with the SD card removed
1. Press (Y) to "restore flashrom"
1. Press (B) to "EXIT"

##### Section V (ii) - Removing ntrboot (3DS Multi System)

1. Launch the Luma3DS chainloader by holding (Start) during boot on **the source 3DS**
1. Select "ntrboot_flasher"
1. Select "Restore Flash"
1. Press (Y) to proceed
1. Warte bis der Prozess beendet ist
1. Drücke (B), um zum Hauptmenü zurückzukehren
1. Select "EXIT" to power off **the source 3DS**

##### Section V (iii) - Removing ntrboot (3DS Single System)

###### What you need

* The latest release of [ntrboot_flasher](https://github.com/kitling/ntrboot_flasher/releases/latest)
