Homebrew Restoring developer UNITINFO?

[supermario666]

A few years ago I turned on the Set developer UNITINFO option on my New 2ds XL, and only now I've realized that it was a bad idea.
Can the features of it be restored? (online communication, Amiibos etc.)

You can go into Luma settings (Hold SELECT while powering on) and disable it.

That doesn't restore the online communication.

Are you sure you aren't banned? What is the error code?

That's the LocalFriendCodeSeed_B ban. RIP

Yeah I tried unbanning it with another 3ds but it didn't work.

 

[Aquadraws]

I can guess both your consoles are banned then.

No my Old 3ds is still fine.

 

[Aquadraws]

Well, most likely you forgot to copy the correct file to your banned console.

I followed every step in the video

 

[Aquadraws]

Oh, a video. Anyways what you are supposed to do is copying the LFCS_B from the unbanned console and replace the one on the banned console with it(it being the unbanned seed).

That's what I did but I will try again and see.

Ok I tried 2 text tutorials and a video tutorial and none of them worked. What is the problem then?

Maybe the serial is banned as well? Not sure if that would give the same error though.
Not common to get those banned but who knows with developer UNITINFO.
Can pretty easily change the serial if necessary.

Where can you change that? In Secureinfo_A? If yes, I tried that also.

 

[Aquadraws]

Yes, you change the serial in SecureInfo, one last thing you could do is comparing both files with the two consoles side by side.

I found out that it is possible to restore them with a NAND backup. I tried to do it with my O3ds's NAND but it just said MBR MBR is corrupted. Why?

You can't just restore a NAND backup from a different console, the encryption is different. You need a special ctrtransfer image.

So does that mean the 3ds will be banned forever?
