I get an error when i downgraded i try to reboot and the screen is complete black but the blue light are lightning and when i press the buttons for recovery the screen is black but it shows a light for wifi and the screen have a little light but nothing shows up :/

 

Damn bro sorry to hear about that. Mine did the same thing too. I had a copy of the nand but didn't bother trying anything after that point. Fortunately for me, all I had to do was purchase a warranty from GameStop (my n3ds is only 2 months old). Basically if you still got warranty, I'd send it to Nintendo for repairs.

 

How is that shit karma?? I bought my system brand new, idfk how that brick happened but I didn't feel like waiting just for my 3ds to come in the mail like a month after. Besides I don't think Nintendo would of did anything. In most cases they don't even fix the systems. All they do is give u a new one.
