Hello, I was installing A9LH on my 3DS but when my downgrade was complete I noticed that I couldn't turn my wi-fi on for the last browser step. I found a other post on reddit that upgrading to a higher firmware and downgrading it again was my only option. I upgraded my system via a game "Super Smash Bros" but then I noticed that my DS stopped working. I tried to soft unbrick it via the soft unbrick method and upated my 3DS to the latest firmware. Now when I power on my New 3DS XL both screens stay black and I can't turn it off only when I remove the battery. When I try to open the soft unbrick method again "L+R+Up+A" nothing happends Is there any possibility that I can solve this issue? Thanks!
