honestly im not sure, it didnt let me boot up godmode i help X and power and it just booted up like normal?You're having constant Arm9 errors? We need details..
can you access either Luma3DS or GodMode9 (with or without the sdcard)?
what's the last you did with it?
have you checked the sd card for errors with h2testw?
So now it works? Weird, probably a failing sd card readeri help X and power and it just booted up like normal?
