Homebrew [Tutorial] How to Fully Unban Using System Transfer (requires 2 3DSs)

[Andarer]

Yeah. We found some neat stuff last night that resulted in an N3DS getting bricked because we were using the CTRCert from a 2DS, which caused the eShop to think the system was an O3DS and caused an update nag. So, in the name of science, we updated and got bricked (duh). It's been amusing. We had someone patch Luma in a way that fixed this though.

So if it's patched, the danger of the system being mismatched by the eShop would be avoided?

As someone else posted, you can change the device that's listed in the header of the Cert, did you do that? Or you had a certificate with 2ds listed in his header?

I'm asking because of the whole "you could end up using a wii certificate in your 3ds" fuss.

So does this generate a new LocalFriendCodeSeed and DeviceCert/CTCert? (the console-exclusive file hidden somewhere that tracks NNID bans among other things)
Interesting, too bad I don't have another 3DS to test this with.

I'm using the CTCert, DeviceID, and Secureinfo_A from an unbanned 2DS, but you can use any 3DS system (not sure if out of region consoles work, though). Nothing was changed in any header, and I've not heard of anyone doing this. Even if they were doing this, they'd need a way to load CTCert into the ITCM since it resides in the OTP and we can't touch that. As far as using all that from the Wii goes, I highly doubt that would work.

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 get this error on my Wii U whenever I try my old NNID on NNID services. A 2802 is an account-specific ban, the difference between it and 2812 is that the latter is tracked by the DeviceID in CTCert instead of just the account.
This means that either when they banned me (not for Sun & Moon, but something else that warranted the exact same ban) they were mad enough that they went in and individually hyperbanned all of my 100+ NNIDs just to make sure I would never use any of those accounts again... or, this just permanently breaks all IDs on the console.
Am I really the only one who gets this error?

(sorry if this is off-topic, but I just want to know)

Personally, I don't see how it would unban the source system, because it's not like it's getting a brand new device id, ctcert, localfriendcodeseed, etc after transferring, right?

From how I understand it, supposedly ctcert is regenerated after the transfer is complete, to match the randomized ID. Given the low success rate, though, who knows.

 

[PF2M]

I'm so skeptical of this, there's about the same ratio of people saying that a system transfer DOESN'T unban the source system, and people saying that it DOES unban the source system.

Personally, I don't see how it would unban the source system, because it's not like it's getting a brand new device id, ctcert, localfriendcodeseed, etc after transferring, right? that wouldn't make any sense from what I know

I'd really like someone to prove whichever side they stand on, be it that it DOES unban the source system, or it DOESN'T, because right now, how I see it, based on how things are supposed to work, it shouldn't unban the source system

Well, let's do some tests, shall we?
To anyone who's about to do this, I want you to help us out here. Download Reisyukaku's eShop Debugger and run it on both systems, and take pictures of their screens. It should look like this:

Once you have the pictures from before, do the tutorial in the OP, and see if it worked or not. Then run eShop Debugger on both consoles again, and take pictures labelled to be from after the transfer.
Once all 4 pictures are taken, post whether or not it worked, as well as how the Device ID of each console changed before and after the transfer. Did they switch places? Are either of them new? Did nothing change at all!?

This will help the scene a bit, so it'd be great if you could help us here.

Since I do have a DSi, I'd also like to know: what happens if you transfer an unbanned device to a banned one? I'm sure that eShop Debugger exercise could tell us.

It comes from here:

Basically, he was wrong when he figured these certs could be generated, but he was right when he noticed they all use the same cert - and the type of console or handheld is in the header, so by editing it you can get it working in another type of console as if it were native.

This is the second part where he notices his initial mistake.

 

[PF2M]

I did a system transfer from my old Wii to my Wii U and dumped the same-format-as-3DS DeviceCert files before and after, and... they switched??? This seems to explain why this guide works like it does. Too bad this really doesn't generate DeviceCerts, darn it. That's the second fakeout with these.

One day, Nintendo. One day.

been 1 week since i did system transfer from banned to stock. 100% stock is not banned and now has cfw on it.

did the banned one get fully unban?

Technically, the banned 3DS will remain banned.
Unless you change the Secure_InfoA and unlink the prohibited NNID.

so dis tut is nonsense?

Wait, this tutorial is quite misinformed.

look this method from @Giodude HERE (You have to do this one to unban the Source 3DS FIRST!)

and now watch this thread from @Wojton HERE (This has been confirmed that it will NOT transfer the ban IF you do the following steps from the previous thread I did mention up there.)

 

[NBAPwns13]

use the fixes so that you can system transfer, also inject blank nnid, and then do the dsiware downgrade

will doing it after the transfer give any imformation? Cause i didn't do it before the trasnfer

Hi there, I'm new to this. Can I get some confirmation regarding this tutorial?
A. Banned 3DS with old NAND backup with different LocalFS
B. Unbanned 3DS (11.1) but without CFW/A9LH installed.

1. inject LocalFS from my prev NAND dump (different) to banned 3DS which result I am able to access online but not Link/Create NNID
2. since i can't backup unbanned 3DS so I continue to system transfer from Banned 3DS to Unbanned 3DS
3. result = Banned 3DS is assign with new LocalFS/movesed and free to link/create NNID, while unbanned 3DS (obtained localFS/movesed from Banned 3DS) now is still able to online but not Link/Create NNID. Am I correct?

4A. What if I system transfer again from the banned 3DS (current free from all) to unbanned 3DS, will it free up the unbanned 3DS?
4B. What if I system transfer from unbanned 3DS to banned 3DS at the first place??
