I was attempting to get my 3ds to patch Majora's Mask 3d with the restoration mod, but it was being stubborn. I attempted to downgrade my Luma to see if that fixed or affected anything, and I did this by updating the boot.firm on the 3ds system itself, not just the SD Card as that was not working. My system then crashed with the Arm11 undefined instruction error. Now all that it does is display the error code when I attempt to boot my console. I am able to launch into the Luma menu, but if I try to boot into my home menu from there the system crashes. I cannot boot into gm9 to load a NAND backup. The Luma on the SD Card is the latest version, and I have tried reinstalling gm9 to no avail. Please Help!
