|
Before proceeding, ensure you have read all of the information on [ntrboot](ntrboot)
|
||
|
|
|
||
|
|
Note that R4i Gold 3DS RTS flashcarts will not be able to be used for their standard functions (such as launching `.nds` files) while the ntrboot exploit is installed on it. This does not apply to the Acekard 2i.
|
||
|
|
|
||
|
|
There are optional steps at the end of the ntrboot boot9strap installation instructions to remove the ntrboot exploit from your flashcart when you are done.
|
||
|
|
|
||
|
|
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). It is compatible with the following flashcarts:
|
||
|
|
|
||
|
|
+ [Acekard 2i](http://www.nds-card.com/ProShow.asp?ProID=160)
|
||
|
|
+ [R4i Gold 3DS RTS](http://www.nds-card.com/ProShow.asp?ProID=149)
|
||
|
|
|
||
|
|
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/))
