I'm using an old 3ds with 11.9 and a 2015 R4 SDHC Dual-Core card (which was pre-flashed) and i'm having problems trying to setup SafeB9S I was trying to do the button combo with a strong magnet (which I also tested first hand) and nothing popped up and it just goes to sleep mode pretty much. So I decided to reflash it using the dsi method. Is this card broken or am I missing some files. and no I dont have CFW.
