Due to recent breakthroughs in 3DS reverse engineering there is now a way to unbrick your 3DS without a NAND backup. Step 1: Brick your 3DS (or else you can't do this) Step 2: create a new folder on your computer calles NAND Step 3: fill it with files Step 4: compress it and make sure it's the same size as a NAND dump. Must be zip file. Step 5: rename it from NAND.zip to NAND.bin (make sure to change the extension) Step 6: put NAND.bin on the root of your SD cars Step 7: insert SD card into your 3DS Step 8: put your 3DS in the microwave -the radiation will change NAND.bin to a valid NAND backup Step 9: It is now unbricked. Have fun with your 3DS.
