THIS IS FOR A9LH AND BOOT9STRAP ONLY!
If you use menuhax, replace every time i say sysnand with emunand. Doing anything to your sysnand without a9lh or Boot9strap will result in a brick!
With that being said....
So many people lately have been reporting bans from unknown causes. This tutorial will help get the 3ds working on the eshop and online games. Frankly, i don't reccomend following this tutorial until the cause of the ban is found out, to avoid getting banned again, but use at your own risk. Account based things like Pokemon bank will be lost from this. Note that your friends list and games will still be there. Also note: you cannot access nnid settings after being banned, even after this method. Your eshop history will also disappear.
Here is what you will need:
1. the banned 3ds
2. An unbanned 3ds
3. Decrypt9 running on both.
Now here are the instructions:
Method 1:
1. boot up decrypt9 on the unbanned 3ds.
2. Go to sysnand options and dump you friendcodeseed_B
3. Put the sd card in the computer and backup the file you just dumped.
4. Download this:

5. Now on the banned 3ds, go into decrypt9 and dump secureinfo_A
6. 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.
7. After that, put all 3 files you made/ downloaded in the files9 folder of the banned 3ds.
8. Go into decrypt9 on the banned 3ds and inject all 3 files. Congratulations your 3ds is unbanned.
9. (Optional) Do a system transfer between the banned and unbanned 3ds. This will fully unban the banned 3ds, allowing it to create an nnid and use all Nintendo related services, not just online, but this will Ban the unbanned 3ds! Atleast in the sense that the unbanned 3ds cannot create an nnid or use miiverse. Online should still work fine. It will behave as if you didnt do a system transfer on the banned 3ds.
As far as i've tested, the unbanned 3ds should still be able to go online along with the banned 3ds, but this is not certain. Also, just in case, do not share the friendcodeseed_B with anyone else, as i don't know what happens when too many 3ds's have the same friendcodeseed. Also if the 3ds blackscreens, that means your cfw is not compatible with the injection, but most are. This could also have strange side effects, but nothing major. After doing this, my folders on my home screen were named after gba injects i had, and game updates needed to be downloaded again, but finished in several seconds.
