Earlier today I was using ds, I was trying to get Pokémon Bank because I heard that it was still up, so I could transfer my Pokémon to Pokémon home before it was discontinued. It told me to enter my NNID password, but I remembered that I had set up my Pretendo ID, so I closed the app and my ds crashed. I opened gm9 and used a NNID removing script. Then when I tried to turn my ds back on, it came up with the error in the attached images. Please help me.
