Hacking My Mii is locked and not mine anymore?

[Chrushev]

Hi guys, I am not exactly sure what caused this, perhaps unlinkin sysnand/emunand or something.

But my main Mii that I streetpass with I cant delete/or edit him. When I try to edit it says its a Mii I recieved from someone else. When I try to delete him it says I cant delete my personal mii.

How can I fix this?

I ran into this when transferring Streetpass Mii Plaza from one machine to another. The new JKSaveManager finally lets you transfer enough things to do it without manually decrypting anything, but you have to transfer your Mii database, so you should transfer Mii Maker as well, and if you do that it thinks all the Miis aren't owned by you.

I'm not sure if there is any solution except using a Mii editor hack to edit the Mii.

It may detect you mess with the save file. Doesnt the mii transfer over from when you unlinked the nands by formatting sysnand?

This happened to me when the 2DS released, and it was a completely hackless console.

This is actually happening on my O3DS that hadnt had anything transfered to it. The only things that involved moving data was creating Emunand and copying sysnand into it. So moving stuff isnt an option for me since there is nothin to move from.

Its completely dumb for Nintendo to now allow you to delete them, you should be able to delete any Mii no matter what.

Well 8 years later here is how to fix it.

Root cause: System ID of the Mii is different from current System's ID

1. Create any mii on the system you want to make him editable on (thats how we get current system's ID)
2. Run JKSM, you may need the 06/30/2016 version, navigate to Shared ExtData --> F000000B --> Export Data and name it something you will recognize (like todays date)
3. Grab the CFL_DB.dat file off of the SD card, either via ftpd or via moving it to your computer and grab the file you backed up from /JKSV/Shared/F000000B/<whatever you named the export>
4. Open the file with Mii Edit Tool https://www.gamebrew.org/wiki/3DS_Mii_Edit_Tool
6. Also open CFL_DB.dat in a hex editing program, for example HxD https://mh-nexus.de/en/hxd/
7. On Personal Mii tab look at system ID, press CTRL + F then select "Hex Values" tab, and type in the first few values of the system ID. It should be somewhere on the first or second line.
8. Go to All Miis tab in Mii Edit Tool and select the mii you created earlier, note the system id there. You need to change the values you found in hex editor to those valies, then CTRL + S to save.
9. Reopen the CFL_DB.dat in Mii Edit Tool and verify that Personal mii System ID matches system ID of the mii you created earlier. If it does, save the file again, move it back to the SD card and reimport via JKSM.

Thats it.
