Hello, I got a little problem, if somebody can help me with, would be great. I tried to downgrade my 3ds to 4.5. I had the right CIAs and everything went good. After all CIAs were installed and it asked for reboot, the 3ds comes up with black screens. I have tried to turn it on without sd card and pressing L,R,A,UP but with no results. It is bricked? Thank you.
