If you already flashed ntrboot to your flashcart, you can follow [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.
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.
| Flashcart Name | Current Price | "Time Bomb"? | 3DS Versions? | DSi Versions? | NDS Versions? | Other Notes |

| [DSTT](http://www.nds-card.com/ProShow.asp?ProID=157) | $9.99 | No | None | None | All | Only models with [certain flash chips](https://gist.github.com/Hikari-chin/6b48f1bb8dd15136403c15c39fafdb42) are compatible with ntrboot. |
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.
The usage of this exploit, regardless of flashing method, requires access to a small magnet if the target device is of a folding style (any 3DS family system that is not the old 2DS with a sleep switch). This is because the exploit requires your device to enter sleep mode while still having access to the buttons.
To test if a magnet will work, hold it on or around the (A)(B)(X)(Y) buttons while the device is powered on to see if it triggers sleep mode. If it does, both displays will go black as long as the magnet is held in that spot.
Fique ciente de que o flashcart não será capaz de ser utilizado para a sua funcionalidade padrão enquanto o exploit ntrboot estiver instalado nele (exceto no caso do Acekard 2i, que permanece funcional *apenas em sistemas 3DS com firmware customizado*). Existem etapas opcionais no final das instruções da instalação do ntrboot para removê-lo do seu flashcart após terminar o guia.
Note que em algumas raras circunstâncias, pode ser possível que o processo de instalação cause um **brick** em um flashcart falso e torne-o permanentemente inutilizável. É pouco provável que isso ocorra, mas mesmo assim somente os flashcarts originais listados são suportados. Para reduzir a chance de receber um flashcart falso, é recomendado que você use um site com uma boa reputação para comprar o seu flashcart, (como o [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.
This method requires temporary access to a Nintendo DS or Nintendo DS Lite that is compatible with your flashcart. This method uses the flashcart to run the ntrboot flasher `.nds` file on your NDS. This means that your flashcart must support launching `.nds` files on your NDS's version. See the flashcart table above for more information.
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 NDS. This means that your flashcart must support launching `.nds` files on your NDS's version. See the flashcart table above for more information.
