# Flashing ntrboot (3DS Single System)

## Required Reading

Before proceeding, ensure you have read all of the information on [ntrboot](ntrboot)

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 on [ntrboot](ntrboot) for more information.

::: danger

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](https://www.nds-card.com/)).
