I recently bought a 3DS not knowing it had CFW installed on it,after updating the firmware on the 3DS,it will no longer turn on and hangs on the blue led. After some research I found that the last Luma update was 6.1.1 with arm9loaderhax.bin. I tried adding the boot.firm and boot.3dsx files from luma 12.1.1 to the root of the sd card and adding the new arm9loader from update 7,when I switched the arm9loader files it went from hanging on the blue led to the blue led coming on for a second and then turning off. Any help would be greatly appreciated
