Wow, that happened to me too. I had to use a tiny screw to unjam the bottom. nothing looked broken, but when I put my Dsi back together, the screens got fuzzy.

Hello, how do you close the system after opening it?

When I opened my dsi to clean the L and R buttons, I removed the case from the top,opposite of what you did. I dont know how to reconnect that small orange ribbon! <:(
