If you have already flashed ntrboot to your flashcart or your flashcart comes pre-flashed with ntrboot, you can skip to [Installing boot9strap (ntrboot)](installing-boot9strap-(ntrboot)) for instructions on how to use it.
Installing boot9strap with ntrboot requires a compatible NDS / DSi flashcart to flash ntrboot to. Additionally, some manufacturers are now selling NDS / DSi flashcarts pre-flashed with ntrboot.
While the ntrboot exploit works independently of system version, the ntrboot flasher (which installs the exploit to the cart) is not. This means that, depending on the versions and devices supported by your flashcart, only certain methods may be available to you.
Note that carts with a "Time Bomb" will no longer be able to launch `.nds` files when they detect that the system clock has passed a date determined by the flashcart firmware. One method to bypass this is to set the system clock to an earlier date.

Ensure your flashcart is able to launch `.nds` files on your device before beginning. Some flashcarts may require firmware or "kernel" files to be copied to the flashcart SD card. Consult your specific flashcart's instructions for more information.
Die Benutzung dieses Exploits, egal welche Flashing-Methode verwendet wird, benötigt Zugriff auf einen kleinen Magneten wenn die Ziel-Konsole zuklappbar ist (irgendein 3DS-Familiensystem, das nicht der alte 2DS mit einem Schlafmodus-Schalter ist). Das ist nötig, weil der Exploit erfordert, dass dein Gerät in den Schlafmodus geht, ohne den Zugang zu den Tasten zu verlieren.
Um zu testen ob ein Magnet funktionieren wird, halte es auf oder in die Nähe der (A)(B)(X)(Y)-Tasten während die Konsole eingeschaltet ist, um zu sehen ob der Schlafmodus ausgelöst wird. Wenn dies der Fall ist, werden beide Bildschirme solange schwarz bleiben wie der Magnet an der Stelle gehalten wird.
Note that the flashcart will not be able to be used for its standard functions while the ntrboot exploit is installed on it (except for in the case of the Acekard 2i, which remains functional *on NDS and custom firmware 3DS systems only*). This means that, for most flashcarts, it will not even display on the home menu. There are optional steps at the end of the ntrboot flashing instructions to remove it from your flashcart when you are done.
In manchen seltenen Fällen ist es möglich, das während des Flashens einer gefälschten Flashkarte diese **gebrickt** wird und somit permanent unbenutzbar wird. Dies ist unwahrscheinlich, aber dennoch nur originale und aufgeführte Flashkarten werden unterstützt. To reduce the chance of receiving a counterfeit card, it is recommended that you use a reputable site to buy your flashcart (such as [NDS Card](http://www.nds-card.com/))
This method requires nothing more than your stock unhacked 3DS and a compatible flashcart. This method uses the flashcart to run the ntrboot flasher `.nds` file on your 3DS. This means that your flashcart must support launching `.nds` files on your 3DS's version. See the flashcart table above for more information.
This method requires temporary access to a second 3DS family device that is already running boot9strap. This does not require your flashcart to support either 3DS's version. See the flashcart table above for more information.
Diese Methode erfordert temporären Zugriff auf einen Nintendo DS oder Nintendo DS Lite, welcher mit deiner Flashkarte kompatibel ist. This method uses the flashcart to run the ntrboot flasher `.nds` file on your NDS.
This method requires temporary access to a Nintendo DSi that is compatible with your flashcart. This method uses the flashcart to run the ntrboot flasher `.nds` file on your DSi.
