soooooooo. I know this question propably got asked thousend of times but i havent found an solution yet. Ok so about a year ago i downloaded the homebrew. After that everything went fine for about a month or so. I opend my 3ds to clean it and my left trigger button was also little bit sticky. I put all the files of the sd card on my pc. I reesembled my nintendo but i didnt put the files back on the sd card and in the nintendo. Then i havent touched my nintendo for about an half a year. Now i wanted to play on my 3ds again but i lost some of the files and when i try to start it withoud the sd card i get a black screen and also when i try to download all the stuff for the homebrew and put it on the sd card in my nintendo it also gets a black screen. I know i could go into the Luma 3d settings thing but i didnt work anymore.

A close encounter of the blurred kind. "More light!"

To rule out possible button problems, provide a FAT32 formatted SD containing nothing but boot.firm

Assuming it is an old model 3DS and the orange LED is my first guess would be the WiFi board became loose. I'm not really sure if the backlights should turn on without WiFi board.

Doesn't look like a software problem, it shouldn't hang like that unless you've done a system update. I would reseat your wifi board
