Chosen Solution

So, I bought a 3ds from someone and decided to jailbreak it, turns out the 3ds is jailbroken already and didn’t come with a SD card so i still follow thru and jailbreak it. yet every time I go to the microSD part in system settings it said “an exception occurred” help pelase

When devices like the 3DS are jailbroken, it can cause issues with SD reading and game card reading. I would still suggest looking at the inside to see if all the pins are in place inside of the reader.
