I had my r4 for a 2 months now but somehow it suddenly stopped working. Now my r4 is stuck on the loading screen. I updated everything and tried removing all the games to see if it was affecting it. I tried cleaning the contact things. Maybe the problem is that sumthing fell on the r4 card around where the micro sd card goes in.. so now theres a crack going down where the open area of where the sd card goes in and going on a slant to about the bottom of the image of the card with the arrow. any help here? EDIT: my small sd still works because my pc recognizes it. Is it also becuz i tried doing that m3 sakura thing? i just got up to just downloading it and puttting it on the card.
