My n3ds won't turn on, the power(blue light) flashes for about a second and then fades away. I tried opening it with the charger plug in, and still no luck. What I've did previously: my n3ds sysnand was 9.0 and already all set up with arm9loader + luma3DS and updated to latest 11.2. I used it to assist my latest n3dsxl to downgrade from sysnand 11.2 to 9.2 using the 3ds.guide website. The method i used for the downgrade is via the DSiWare Downgrade (App Injection and Second 3DS). Now that I got everything working on my n3dsxl, but when I tried to open my n3ds it doesn't start anymore. I think I might have causes the problem, when I didn't go through the initial setup on the source 3ds after the transfer of data from the source 3ds to the target 3ds, I just power off the n3ds after I saw that choose language screen. I then use this source 3ds' sd card in my target 3ds as it's sd card. I don't remember which sd card I used to replace the source 3ds (n3ds), but I do remember that I didn't need to follow through with the initial setup and I could load straight into the home menu. I even check in the Settings, and found that it were revert back to 9.0. I powered off the n3ds, and went on with continuing with my downgrade on the n3dsxl. Do you think it's because I didn't go through with the initial setup that causes this issue? I'm really worried and I don't even know what's the problem with my 3ds, is this what a brick means? Do any of you expert know what I can do. It's late where I'm living, and I don't have the energy to check my grammar/sense in this post. I hope you guys understand. Please tell me what other information you need from me, for you to be clearer on how to assist me. Thank you all for helping.
