How to upgrade your DSTWO fireware on a 3DS(ver 2.0)

Godslash

This way is just for who only has 3DS console. We suggest you to upgrade on a never upgraded console or a DS, it's much safer!

This is a way to upgrade DSTWO fireware on a ver2.0 3DS console directly. Please read the red sentence carefully, or your DSTWO may be broken!

NOTE: Please follow the guide, or there is a risk of bricking!

1, Essential condition: your DSTWO must be recognized on the ver2.0 3DS console. And you can see the icon of it.


2, Upgrade.
(i)  rename the dstwoupdate.dat as dstwoupdateb.dat. Then copy dstwoupdateb.dat to the root of microsd card.
(ii) Insert microsd card into DSTWO, then inject DSTWO into 3DS console. Turn on the console and enter DSTWO, you will see this screen:

(it also appears on Japanese version console), please stay here and wait 3 minutes (it's very important, and must be 3 minutes! Or it's very dangerous for DSTWO!), please dont do anything except waitting :p
Turn off the console after 3 minutes, then delete dstwoupdateb.dat file from your microsd card. (very important! You have to delect it!)
Ok, that's all, enjoy DSTWO on your ver2.0 3DS!

Just to make it clear: delect means delete (and inject = insert)

Hello Ja9.
No this doesn't work with dsonei.
The way to upgrade your dsonei to support 3DS 2.0.0-2 is here : http://forum.supercard.sc/thread-5607-5-1.html. Cf PCrep post.

@HDWalter

This works on a 3DS, even one updated to 2.0
The DS2 CPU handles the update on its own without any help from the 3DS (except for providing the ds2 cpu with power)
