So i'm in the process of installing a9lh on my n3ds (11.0) and I've followed the instructions fairly well. I got to the CTR stuff and am currently on 2.1.0, but I rechecked in settings being the paranoid guy I am. When my n3ds booted back up, the screen was all discoloured. I could see everything like the settings app and such, but the top screen was going between green and purple and just looked generally jacked. I took the battery out as I've heard that's a good way to shut off the system in 2.1.0, but now I'm scared to even turn it back on. I have a NAND backup, but i dont know what to do.
