    With the recent ban wave of CFW it's very common to use a public Local Friend Code Seed (LFCS) to unban your 3DS.

    If you intend to inject a public LFCS, I recommend before that dumping first your own and storing on your computer somewhere safe.

    This thread shows 3 methods for unbanning:
    http://gbatemp.net/threads/all-3-methods-to-get-unbanned-from-recent-ban-wave.450679/

    But it uses Decrypt9, so I decided to make this simple guide on how to inject and dump the LFCS with GodMode9.



    Dumping the seed from your 3DS with GodMode9:


    1) Boot into GodMode9

    2) Navigate to [1:/rw/sys/]

    3) Press (A) on LocalFriendCodeSeed_B

    4) Select "Copy to 0:/gm9out"


    Hurray, it worked



    Injecting the seed to your 3DS with GodMode9:


    1) Put the seed at the root of your SD card.

    2) Boot into GodMode9

    3) Navigate to SD card [0:]

    4) Press (Y) on LocalFriendCodeSeed_B to copy it

    5) Navigate to [1:/rw/sys/].

    6) press (Y) to paste it

    7) Select "Copy paths(s)", and press (A)

    8) You'll be asked to unlock writing on SysNand (lvl1), press (A)

    9) Proceed with the sequence shown in the screen. (left, right, down, up, a)

    10) Select "Overwrite file(s)"

    11) You'll be asked to unlock writing on SysNand (lvl2), press (A)

    12) Proceed with the sequence shown in the screen (Left, Right, Down, Up, A)


    Hurray, it worked

    i would add to backup the old, banned friendseed just on the very low chance that someone finds a way to revalidate them somewhere along the line

    I changed the original post with a sentence remembering then to dump their own seed before injecting a public one, thanks for the tip.

    I also made some changes on the original post to make it even easier to do and have.
    I think it has a better format now.

    but won't the public seed be banned, too?
    what are the disadvantages of the public seed?

    Nintendo can ban public seeds, but the community has tons of then, so there is no point in worrying about it.
    If your console gets banned again you just need to inject a new seed again.
    There is not much disadvantage in using a public seed. If you were banned I highly recommend using the most recent one.

    When you're banned, your friends can't see you online.
    You can't play online when you're banned.
    A new seed is used when you want to unban yourself from online.

    If you go on your friend list and you appear online, you're definitely not banned.

    I don't get the point of your question.
    Your friends still can see you. Your friend list will remain.
    Your NNID still will be linked with your console.
    I don't know exactly what a LFCS do,
    how it works, but it gets us unbanned without any consequence.

    The problem is, nobody knows exactly how Nintendo banned everybody, what qualifies for a ban, when a next one will how and how to prevent yourself from this.

    My guess is on the Spotpass. I highly recommend disabling the Spotpass functions on System Settings.
    Sending your data to Nintendo when you're using a CFW isn't the wisest move.

    I totally agree, but I would like to know what that localfriendscode seed file is used for. from its naming I would guess it is some kind of identifier for local gaming? maybe streetpass?
