So awhile ago I added cfw to my boyfriends 3ds and it has been working perfectly fine, downloaded a ton of games for him and hes been enjoying it. Last night I opened up his system to replace his d-pad and abxy buttons since the original ones were starting to have the paint chip off and become annoying when in use, however, when the system was put back together it now wont boot up with an sd card inserted, anyone have any idea what that might be the reason of? I feel like I didnt break the sd card slot since it only turns on when one isnt inserted so surely it can tell when one is put in right? Then so what might my problem be with cfw? It's been awhile since I hacked it so any help would be greatly appreciated. I will mention recently before this we upgraded the sd to a 64gb (I did reformat to fat32) but if that helps give any other info.
