___

The following is an optional section that will allow you to restore your flashcart to its original state (to allow it to be used for its standard functions).

Note that the Acekard 2i retains its ability to launch `.nds` files while having the ntrboot exploit installed. This only applies when the Acekard 2i is in a 3DS running some kind of custom firmware! While the ntrboot exploit is installed to the Acekard 2i, it will be unable to launch `.nds` files on stock NDS, NDSL, DSi, or 3DS system.

Do not follow this section until you have completed the rest of the instructions on this page.

##### Section V - Removing ntrboot

###### What you need

* A versão mais recente do [ntrboot_flasher](https://github.com/kitling/ntrboot_flasher/releases/latest)
* The flashrom backup corresponding to your flashcart    
  + Note that if you followed "Flashing ntrboot (3DS Multi System)", the flashrom already exists in the correct location and does not need to be downloaded
  + If you do not know which HW revision you have, just try all of them. Only the correct one will allow your flashcart to launch properly from home menu, but flashing the wrong one will not brick the cart:
