Yes, but it requires a hardmod to do so. If you're going to hardmod your 3DS, you should hard mod it before downgrading. That way, you can have a NAND backup in case anything goes wrong during the downgrade.
I see, so there is no way to extract it purely with software like we can do with systems already on 9.2? I'm skeptical of my soldering abilities, but I suppose I could give it a shot. Thanks for the info.
