I want to try unbanning myself by injecting LocalFriendCodeSeed. If I get the LocalFriendCodeSeed file from a friend's 3ds with CFW, would we end up having the same friend code afterward? Would this cause issues if we both want to go online? Alternatively, I could just get it from my other 3ds, but that one doesn't have CFW and is on 11.1, so I only have access to Homebrew. Is there any way to get that 3ds's LocalFriendCodeSeed on that firmware?
