If you already flashed ntrboot to your flashcart, you can follow [Installing boot9strap (ntrboot)](installing-boot9strap-(ntrboot)) for instructions on how to use it.
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.
Țineți cont că flashcart-ul nu va putea fi folosit pentru funcțiile lui obişnuite cât timp exploit-ul este instalat pe el (excepție în cazul unui Acekard 2i, care rămâne funcțional *numai pe dispozitivele 3DS care au custom firmware instalat*). Există paşi opționali la sfârșitul instrucțiunilor pentru instalarea ntrboot-ului cu scopul de a-l şterge de pe flashcart după ce ați terminat.
Note that in some rare circumstances, it may be possible for the flashing process to **brick** a counterfeit flashcart and render it permanently unusable. This is unlikely, but nevertheless only original listed flashcarts are supported. 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/))
Note that more recent 3DS versions have blocked access to some flashcarts, and some flashcarts have always been blocked on the 3DS. This leaves them unable to launch the flasher `.nds` file on some (or all) versions. The ntrboot compatible flashcarts are able to launch `.nds` files on the 3DS (under the listed versions):
[Flashing ntrboot (3DS Multi System)](flashing-ntrboot-(3ds-multi-system))
This method requires temporary access to a second 3DS family device that is already running some kind of custom firmware (such as boot9strap or arm9loaderhax).
Note that more recent DSi versions have blocked access to some flashcarts. This leaves them unable to launch the flasher `.nds` file on newer versions. The ntrboot compatible flashcarts are able to launch `.nds` files under the following versions:
This method, once ready, will require temporary access to a [Powersaves](https://amzn.to/2fb3VY7). This method is not yet complete, and as such is just a placeholder page.
