### Required Reading

Afore proceedin', ensure ye 'ave read all o' th' 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.

Note that in some rare cases, it may be possible fer th' flashin' process to **brick** a counterfeit flashcart n' 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.net/))
