So from what I understand about how the downgrade feature works, It reads the encryption of your nand file and applies it to the gateway.dg and then builds an older nand that it writes to your sysnand. So I have a theory that I want to try but I figured I would post it here first. My buddy upgraded his 3ds to 9.4 on accident. If I were to install a nand mod on his 3ds, dump his nand file then put that and the gateway.dg file on my sd card and then use the downgrade feature, It would write a valid 4.2 nand for his 3ds to my sysnand. If I then dumped that nand using a hardware mod on my 3ds and restored it to his then in theory it would downgrade him to 4.2. After this I could just use my nand mod to restore a valid nand to my 3ds. Does anyone know if this might work? Just a Theory.

His nand will be encrypted with a different key that your 3DS doesn't have. So your 3DS can't do anything with his nand.

No but I believe the Downgrade feature reads the key from the NAND.bin file on your SD card. So If I had his Nand.bin file on my sd card it would encrypt the new nand with his key.

Ah ok thats what I was wondering... so the downgrade feature reads the key from the 3ds directly then?

you are just guessing how it works, we don't know how gw is downgrading the consoles.
your idea about recreating the nand, i doubt that is the case.
