    I have my actual NNID on my 2DS in emunand (I system transferred it over). I use rxTools on the latest FW, but my 9.2 FW on my 2DS is just a formated one more or less. What I want to do, is downgrade my emunand from 9.8 to 9.2 (which I think can be accomplished with cia installers), and then flash it to my 2DS sysnand, so I dont have to boot into emunand for my main console ID (basically relinking emunand and sysnand). What tools/methods should I use for this?

    Solution:
    -Dump both the EmuNand, and SysNand
    -Use rxTools to dump files from the emunand (movable.sed, ticket.db,etc)
    -dump the emuNand fat partition (you can do this with rxTools)
    -extract the neccessary save files from the emunand fat partition (friendslist, puzzle swap, etc).
    -Using Emunand tool, inject the sysnand into your emunand.
    -Launch rxTools, and inject the files (movable.sed, ticket.db,etc)
    -boot into emunand, and set up the system like usual. then power off
    -dump the emuNand fat partition, and inject the saves from the previous fat partition
    -inject the modified fat partition to emunand, and boot into emunand
    -You should now have it downgraded to whatever the sysnand was on, and if it boots, it should be safe to flash this emunand to sysnand with the gateway menu

    Yeah I have done that before, the problem is with no gateway card you can't boot into gw emunand so until you can do that I can't help

    If think you can manually transfer your eshop content from emunand to your sysnand by injecting to your sysnand the ticket.db and the movable.sed from your emunand (with rxtools). But you should try this on a 9.2 emunand first, then flash the 9.2 emunand.

    All I need to do is downgrade my emunand. I can then use the GW menu to flash my emunand to sysnand, and done.
    All I want to make sure, is that I'd be fine using FBI or something to "downgrade" the system version with cubic ninjask

    If you use Cubic Ninja and FBI, you'll be on sysnand. You want to downgrade emunand so you need to be in emunand before you can downgrade it. RonHero personally helped me downgrade, it's a HELL of a process but it worked!

    You can't do anything without a gateway card

    Am I missing something?

    If you're just wanting to use your NNID on your sysNAND, isn't it simply a matter of going into NNID settings on sysNAND and choosing "link an existing NNID" instead of creating a new one.

    Will that link the sysnand with the emunand too? there's some things I wanted to have on both that are only on my emunand, like friends list, and Eshop content

    I'm using the tutorial to manually transfer. Since I can use rxTools, I think I can just copy over the movable sed and ticket.db

    I'm making progress... I just dumped all the emunand files in rxTools (movable sed, ticket.db, etc) and injected it into a copy of the sysnand which is now my emunand. I'm missing a few things, like friends list, so i need to recover that

    Using rxTools, I was able to dump the fat partition, so transferring stuff should be easy

    It worked, details in the first post
