I recently updated my mt-card to v1.1 and setup the emunand. Today when I turned on my 3ds, the exploit failed to work. The profile screen loaded. My real firmware was still 4.5. I had to reinstall the exploit from the blue MT-Card and things are back to normal. I did remove the network connection from my base firmware before turning off my 3ds last night (But i cannot see how this will make a difference) Before people comment in mass: I did not update my main firmware to 7. My base fw is still 4.5. How did this happen? Should I be worried that this happened?
