Does the camera work at all? And does it display the surroundings, and it just freezes when you click take a pic?
Can you perform a
CTRTransfer? Just to eliminate the issue is not software related problem, if you get an error doing that in GodMode9,
i suggest using a free sd card, formatting fat32 32kb and testing with h2testw if you haven't done already, if you did, skip this step.
If you've encountered an error on GodMode9 starts to act weirdly, take a picture with your phone and post it here.
If that didn't work, you can also try
CTRTransfer type D9 by
@TurdPooCharger .
Other things you can check, if it's
hardware problem, do this only after you've done the above, open up your 3DS re-seat the
WiFi chip by taking it off and placing it snuggly again.
Doing the same to the
sd card reader.
The only other thing left is the
cameras, and if they're malfunctioning (confirmed if they crash the system when you take a pic
, the issue described above), it's a painful process to to fix/replace, i hope it's not the case for you.
