The following are optional sections 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 any of these sections until you have completed the rest of the instructions on this page.
