DsWiFiPWN is a way of having a backup NAND dump/restore function on your console!

​

DsWiFiPWN is basically a way of having DSIwareHAX installed over your consoles DS wifi settings.

What this can achieve is rather basic: the ability to dump/restore NAND backups of any console that this exploit(?) may be installed on.



Yes, while A9LH is essentially invincible, there are cases where A9LH has been worked around by Nintendo. When A9LH first came out, consoles that updated had A9LH overwritten,

however

most

custom firmwares have fixed this issue in the form of FIRM protection or sustained use of emunand. However recently Gateway users had an issue that if they used Gateway CFW with 11.3 Sysnand, A9LH was overwritten, even if they didn't update whilst using Gateway. If you ever find yourself in that situation for whatever reason, but you have DsWiFiPWN installed you can just simply restore an earlier NAND backup.



Method:

First of all, acquire your favourite exploitable DSI game.

Download the exploitable public.sav save file for your game, refer here

Copy your exploited save file to your SD card

Open FBI or Godmode9 on your 3DS, and navigate to these file locations: Spoiler: File locations Fieldrunners USA Region: TWLNAND-> title-> 00030004-> 4b464445 -> content Fieldrunners EUR Region: TWLNAND-> title-> 00030004-> 4b464456 -> content Legends of Exidia USA Region: TWLNAND-> title-> 00030004-> 4b4c4545 ->content Legends of Exidia EUR Region: TWLNAND-> title-> 00030004-> 4b4c4556 -> content Guitar Rock Tour EUR Region: TWLNAND-> title-> 00030004-> 4b475256 -> content

There should be a .app file in this folder, copy that to your SD card and rename it to "00000002.app"

Copy your new 00000002.app and paste it in this location: TWLNAND-> title-> 00030005-> 42383841-> content (overwriting the .app already there, though please back it up first!)

Create a new folder with the filename "data" in this location: TWLNAND-> title-> 00030005-> 42383841

Paste the public.sav you downloaded earlier into the folder you just created

Download fwTool and paste it to the root of your SD card.

Reboot your 3DS

Open the Settings application, then go into internet settings, then into "Nintendo DS Connections"

If you have followed this guide correctly, you should boot into your DSI game. Launch the exploit of the game you installed and it should boot into whatever "boot.nds" you have on your SD card root, it should be fwTool.
