My uncle was hacking my 3ds for me, I'm not sure what version it was but for him to finish he needed to download a certain game. He couldn't so he gave the 3ds back to me and I just continued to use it not completely hacked. I was a complete idiot and decided to update the 3ds. When I did it went to a black screen. Now the only things that lights up when I turn it on are the power and or the charging light if it's plugged in. The screen won't turn on and I can't turn it off so it just stays on until it runs out of power.
