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

[xBleedingSoulx]

I personally would still do it and transfer the ban to one of my o3DS, preferably my non-XL o3DS. If only I could do n3DS > o3DS transfer. >.>

A method to bypass all bans has already been discovered, but there's not been any sort of public release due to how impractical and unpredictable it is. Though at least it doesn't ban a completely innocent system.

I never told people to ban an innocent system. I told people what DS they used was at their own discretion and suggested broken ones or throwaways. That did sound accusatory.

I dunno what Joon is complaining about tbh, he could just transfer the ban back to the original system again if it didn't become unbanned again after NAND restore.

I never said you did. Regardless of the status of the system, it seems to me that it still gets banned. This qualifies it as being innocent as it itself didn't do anything to warrant the ban.

Yes, but it's really the owner/obtainers choice to make that assessment of their own device right? Some people would happily ban an old 3DS in their closet to unban the one they use daily.

Guys guys please.

First of all, nice to hear another method is in the works!
Second, please don't fight over this! Joom is right that is does not "fix" the ban, and that it "sacrifices" an innocent console, but respect each other.
This is making me terribly anxious.

Maybe this will work (Copy-pasta from OP and Giodude's guide):

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. With decrypt 9 backup your unbanned friendcodeseed_B
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:

8. Now on the banned 3ds, go into decrypt9 and dump secureinfo_A
9. Open secureinfo_A in a hex editor. The very last line should be your 3ds console id. To confirm this, it should match up to the code on the back of your 3ds. Without changing the first 2 letters, just change some random numbers and make a new id.
10. After that, put all 3 files you made/ downloaded in the files9 folder of the banned 3ds. (3rd file being the unbanned friendcodeseed_B)
11. Go into decrypt9 on the banned 3ds and inject all 3 files. Congratulations your target 3ds is now unbanned.
12. Profit!

That's exactly what the full guide should be, thus why I linked @Giodude 's guide.
Maybe I should simply copy-paste that.. as the main guide?

i doubt it.

If the 3 files pasting worked, a system transfer wouldn't even be needed to begin with.

The 3 files injection is part of the guide. It HAS to be done before the System Transfer can be performed.
Not sure about SecureInfo_A though.

NNIDsave removes NNID link (from 3DS perspective)-> required.

AFAIK Secure_info transfer hasn't been necessary

However, it will not resolve the 2812.
The moment you try create a new NNID, it'll get locked out.

Well considering the target 3ds will be banned even after restoring an old NAND. I'd say yes.

I'd try but there is no way to transfer from 2 different regions.

Yeah the NNIDsave is required to transfer, the rest is not. And without the transfer the NNID linking does not work, I am aware.

I did put warnings that the target would be banned though.

Yeah, I just added the steps required to unban it afterwards.

Alright well, do you mind if I had you edits to the guide? I'm gonna go to bed before this thread blows up. Blood pressure, shelbs, blood pressure.

Sure, no problem.

Alright, thank you. Will credit you as part of the guide.

I tried this before the post, and worked, but with some differences of you'r guide, when i succesffully transfer from 3DS-1 banned to a 3DS-2 banned too, the 3DS-1 was unbanned, got eshop access and NNID creation, but i had the online error, before did the system transfer i injected the original LocalFriendCodeSeed_B, and after all the transfer process, y checkout the LFCS and it was the same of the backup, same happens on the 3DS-2, i wonder if u compared the LFCS that was banned on the source console and the LFCS after the transfer, maybe you have the same you used to bypass the online error, and after the transfer the 3DS keep the LFCS you usedto bypass the online errror.

And as an optional option to you'r guide, and if you consider to put it on, before to do the system transfer, i made backup of the banned movable.sed, and after all the system transfer, i injected the original banned movable.sed, i had to repeat the configuration console step, but when the menu appears, i had all the games, saves, themes, and any other thing i had before the system transfer, with full eshop acces, new fc (i got this one when i did the system transfer, but only got worked bypassing the online error injecting a public LFCS after the system transfer), i kept all the files on the micro sd and this worked, maybe for some people this could be a way to avoid the work of reinstall all the games, saves, etc etc.

Sorry about my english, but this community gave me a lot of information, help, and many other stuff, that i want to help with some i did to other people.

So you did tranfer a banned system to another banned system the target system is still banned and the source one is totally unbanned,is that what you mean?

 

[MattKimura]

@shelby--san @Majickhat55 I came up with a new idea. What if me or someone offers a service, to use my own 3DS as a slave for system transfers to receive banned data from everyone's 3DS. cleansing a bunch of 3DS in the process.
Example: My 3DS (Banned) and two other 3DS (Both banned)
They both system transfer to my 3DS one at a time and both 3DS will be ban free, while my slave one will be banned.

Would this be a good idea to help unban some users? Aside from the shipping problem?
Basically going from banned to banned to remove bans left and right.
