    Sorry for creating a new thread in an interval of 24 hours, but is it possible to downgrade 9.4 consoles?
    AFAIK it's not possible, but I'm just asking.

    Perhaps we should look into the downgrading process that Gateway made for their launcher, and perhaps try to recreate it/remake it for consoles with newer firmwares.

    You wanted to see where I live? You stalker...
    It's possible. You just need to have a USB hardmod on your 3DS and a NAND backup of your 3DS that was on a lower firmware. After that, you can restore your 3DS back to that old firmware.

    Otherwise, you're stuck where you are.

    Either way, you'd need a backup of an older firmware.

    Nope, false.
    Backup the 9.4, inject the keys into GW's dg files, then downgrade.

    I will verify. Pretty sure I've seen this posted in a thread before.

    So you have never personally performed this magical feat?

    Not sure if you're asking out of curiosity, but in case you upgraded your 3ds and doesn't have a nand backup all that you can do is to get over it and buy a 2nd 3ds, like I did.

    So, that being said, no downgrades for 9.4 yet. The process GW used can't be ported to 9.4 as a handful of key exploits were patched. If we had 9.4 fully exploited then yes, we'd be able to downgrade any firmware.

    "inject the keys", though? It's more than likely not possible.

    You probably could Hardmod your 3DS, dump the 9.4 NAND and export + decrypt the fat16 Partition of it.
    I did this with my 4.5 Partition, not sure if it works with 9.4 NAND, too.

    But a way to inject the keys of the dg-files? I'm not sure how and where.
    It could be possible this way, but no one knows how to do it yet.

    Don't you need some per-system keys or a xorpad or something to decrypt the fat16 partition?
    Also the .dg files are just a bunch of titles and a ticket.db, you can't make much use of them without some sort of software exploit to install those. There's no magical keys involved.

    I'm not so sure, I'm sure if they could inject the keys already exist cfw as it had long for PSP

    You can use NCCH Decryptor to create xorpads for your Fat16 Partition.

    Not if you're on 9.4 without a backup, though.

    If you don't have xorpads, you could ask someone who can create the xorpads for you, or not?
    you send someone the ncchinfo.bin (created from YOUR Nand) which you has created with ctrKeyGen.py.
    Someone creates the xorpads for you.
    Profit?

    EDIT: Could try it with the 9.2 NAND of someone who has sent me his 3DS for a USB-NANDMOD
    Will post my result here after trying

    I'm pretty sure that's also not possible, NAND is encrypted with per-console keys (0x04 is per-console, I think.)
