    NOTE : Requires A9LH. We do not know if this works on redNAND/emuNAND, try at your own risks!
    You have been warned!

    The ban is transfered to the target system, but unbanning steps (does not inclde the abillity to relink/create an NNID) are included in the guide!


    So if you try this, PLEASE try it only on a 3DS you own, and are willing to "throw" online functionnality of away, like a used one, or something, NOT a friend's or family's 3DS, as the linking/creating of an NNID WILL NOT WORK ANYMORE.


    You will loose saves, games, Friend Code, StreetPass Data, etc. on the source console.


    This only works if you transfer a banned system to another (the target can be banned, or not, it does not matter), the opposite DOES NOT work!

    Credits go the @Majickhat55 for the method, and to @ForeverEternal for some parts of the guide. I only wrote the guide based on @Majickhat55 's experience.



    Quick Note :
    Transfers only work in the following ways :
    - Old 3DS to Old 3DS (includes 2DS)
    - New 3DS to New 3DS
    - Old 3DS (includes 2DS) to New 3DS
    - New to Old DOES not work!

    Relinking your NNID to another console should not work, and even if it does, it's not recommended to do so.
    Please create a new one for safety measures, or don't use any.

    Alright, so on to the tutorial!

    First of all, follow this tutorial to unban the banned 3DS : https://gbatemp.net/threads/tutorial-how-to-unban-your-nintendo-3ds.449251/ <-- Read the post in its ENTIRETY before attempting it!

    Once you are done :

    1. Make a NAND backup of BOTH systems, as well as save backups of the source 3DS; the target will be fine as long as you restore a NAND backup.

    2. OPen Decrypt9 on the unbanned system, and go to SysNAND Options > System File Dump... > LocalFriendSeedCode_B. Store that somehwere, you will need it!

    3. Backup both SD cards to your PC. Give names to the folders to differentiate both 3DS's!

    4. Perform a System Transfer from the banned system to the other system. It will throw an error if you do not apply the unban method!

    5. Once the transfer is done, you may restore the target 3DS's NAND backup, as well as SD contents from your PC if necessary.

    6. Your source 3DS, which was banned, should now be fully unbanned, with the abillity to link a new NNID. All saves, NNID, and FC will be gone, though. Your target 3DS is now banned.

    7. Download this blank nnidsave.bin :
    https://cdn.discordapp.com/attachments/202581739959353344/249934940639068170/nnidsave.bin

    8. On the now banned system, open Decrypt9, go to SysNAND Options > System File Dump... > SecureInfo_A.

    9. Open SecureInfo_A in a hex editor. The very last line should be your 3ds console's serial ID. To confirm this, it should match up to the code on the back of your 3DS (it will be located under the top cover plate on a New 3DS!). Without changing the first 2 letters, just change some random numbers and make a new serial ID.

    10. After that, put the new SecureInfo_A, the unbanned LocalFriendCodeSeed_B (backed up from before the transfer) and the nnidsave.bin in the files9 folder of the banned 3ds.

    11. Open Decrypt9 on the banned 3DS and go to SysNAND Options > System File Inject... > SecureInfo_A and then do the same with LocalFirendCodeSeed_B. Press B > System Save Inject.. > nnidsave.bin. The banned system should now be unbaned, though you will not be able to link or create an NNID on it.

    12. Profit!

    This method has not been tested by a lot of people. Please give feedback!

    What happens if you try to link the old nnid to the systems, will it work on one of the systems (from my knowledge it should work on the target system, even if you use an nand dump from before a transfer, but I could be wrong).

    AFAIK the NNID is not banned (my NNID is working just fine on my Wii U), so most likely, after the system transfer, it will work on the target system.
    Please correct me if I'm wrong, though.

    so waiting a few Day and doing system transfer back to the original 3ds will allow you to have a unbaned 3ds with your nnid.
    If this is the case, you should maybe warn the people that its not possible to transfer from a new 3ds to a o3DS/2DS (if I'm not wrong), which would result in the nnid being stuck on new 3ds systems without the help of nintendos support.

    That could be the case, yes! We do not know yet, though. Maybe someone could try it? (I can't try it as I only have a New 3DS and Old 3DS, and the banned system is my New).
    I have thought about writing this in the guide, but I thought it was unnecesary. I will add it to the guide. :)

    Even if your NNID isn't banned, you can't connect it to the console since you essentially sent that to limbo too.... It's still linked on the server but not to your DS anymore because of the transfer. Not to mention, I wouldn't recommend using any NNID that is associated with a banned console regardless. That's just common sense.

    But, Once the Switch comes out, the NNID from your banned console should be very safe to use there as the 3ds will later on become irreverent. I doubt that nintendo would check if its on a banned console or even bother with it when the next gen consoles come out for handheld gaming. Everyone, these were the last good games to come out of the 3ds. It is time to move on. They have been banned. Time to look forward to next gen. ;)

    I've just tried this. Transferred my banned 3DS to my Unbanned one and it worked. They're now swapped!

    So wait, this gets past the 011-6901 error? Because this seems like it's just the same thing as using the LCFS from an unbanned system. The CTRCert is still banned.

    Amazing! :D
    Thanks for your feedback!

    Please vote in the poll to give an idea of the success rate. :3

    It would seem to completely bypass EVERY sort of ban. I would try it if I were you!

    I've already unbanned myself through other means. My point is though, can you link a new NNID to a previously banned system after doing this and then access the eShop or Pokébank without receiving 011-6901? "Seems" isn't good enough for me.

    Just to confirm, when I did the system transfer my older 3DS is now banned but it can still play online. My Newer 3DS is now ban-free and I have created a new NNID on it. EShop access has been restored as well as online play :)

    Thanks for the heads up!

    Yes, you will be able to link a new NNID after doing this. The 3DS goes back to a fully clean state.
    Though I would still recommend a NAND backup in case.

    I can confirm a new NNID can be linked to the system with no errors once this has been done.

    The banned system could be unbanned with a NAND backup if you did one prior. ;)
    Glad it worked out for you!
