With the recent ban wave of CFW it's very common to use a public Local Friend Code Seed (LFCS) to unban your 3DS.
If you intend to inject a public LFCS, I recommend before that dumping first your own and storing on your computer somewhere safe.
This thread shows 3 methods for unbanning:

But it uses Decrypt9, so I decided to make this simple guide on how to inject and dump the LFCS with GodMode9.
Dumping the seed from your 3DS with GodMode9:
1) Boot into GodMode9
2) Navigate to [1:/rw/sys/]
3) Press (A) on LocalFriendCodeSeed_B
4) Select "Copy to 0:/gm9out"
Hurray, it worked
Injecting the seed to your 3DS with GodMode9:
1) Put the seed at the root of your SD card.
2) Boot into GodMode9
3) Navigate to SD card [0:]
4) Press (Y) on LocalFriendCodeSeed_B to copy it
5) Navigate to [1:/rw/sys/].
6) press (Y) to paste it
7) Select "Copy paths(s)", and press (A)
8) You'll be asked to unlock writing on SysNand (lvl1), press (A)
9) Proceed with the sequence shown in the screen. (left, right, down, up, a)
10) Select "Overwrite file(s)"
11) You'll be asked to unlock writing on SysNand (lvl2), press (A)
12) Proceed with the sequence shown in the screen (Left, Right, Down, Up, A)
Hurray, it worked
