Today, I was trying to get Custom Firmware on my 3DS using this guide https://3ds.guide/ Everything was going fine until while trying to do the CTRNAND Transfer, my console turned off. Ever since then, my 3DS stays on a black screen whenever it's turned on. I've been trying for hours and hours to see if there's anything I could do to fix it but nothing has worked yet. I don't know if there's any way I could fix this but I'm begging for help. I need this 3DS to work.
