Okay now I believe my problem is a little different then most of the people on here but I also may be wrong but I updated my 3DS System before the flashcard and now I keep getting a message like this;
An error has occurred
Press and hold the POWER button
to turn the system off.
Please refer to the
Operations Manual for details.
and my system is V4.2.0-9U
I have tried formatting the SD Card with my files on it... and now everythings gone but that doesen't really matter I just want it to work, and no I don't have a DSI so I cant update it through any dsi please help
