Hacking Same Friend Code after B9S install system transfer.

[mfmike]

So, at some point over the course of installing B9S on my 11.4 stock 2ds from an 11.4 a9lh 2ds, our Friend Codes are exactly the same. It should be noted, I also used a public friend code seed to unban the now B9S device. The original a9lh 2ds never received a ban.

How can I change one of our friend codes in the least painful way possible? The only game with a save I care about is Animal Crossing.

SOLUTION: (Courtesy of squall14716)

1. Using GodMode9 navigate to SYSNAND CTRNAND:/data/{hex id}/sysdata/0010032/
2. Press (R+X) on the "00000000" to Rename it
3. Press up once to change the name to "10000000"
4. Press (A) to confirm the change
5. Press (Start) to reboot
6. Go to friends list and it will show up as "????-????-????-????" until the device connects to the internet and re-issues a new friend code.
7. Success!!!

This seed is something different...

Delete the friend save using GodMode9. To do this, open GodMode9, go to SYSNAND CTRNAND:/data/{hex id}/sysdata/00010032 and delete or rename the "00000000" file there. If you delete it, I'd recommend backing it up first, just in case.

I saw this, but I've never heard of TinyFormat and that seemed like more steps than should be needed...

This sounds more reasonable, I'll be trying this first rather than doing a system format.

EDIT: The solution from squall14716 worked PERFECTLY! Thank you!

I knew that there was a smarter way but this was the only way I found
Nice to know that it can be done a lot easier
