Hacking Question on Mii transfering

[Demnyx]

Hello , I'm new on this forum
I want to know if we can backup Mii informations on extdata ( F000000B ) from a 3DS and then inject it on another New 3DS without risks ? ? Both with Luma and A9LH

I don't know if its the appropriate part of forum

Thanks you !

Thanks you !

Yes you can. I recently did it when I transferred my Mii data from my O3DS to my N3DS.

Thanks you very much !

There isn't any bug ? The personal mii is recognized ?

 

[Ryccardo]

The personal mii is just the first one in the database, no problems here...

Of course, it will now be recognized as a foreign Mii and be uneditable.
To fix that, after importing the database, you should create a new Mii on the destination console, export the database again, and edit it copy-pasting the console ID from that new Mii to everyone else (then using FixCRC)!

Thanks you for your answer !

But , how to edit it ? I should use FixCRC but how ?

I downloaded 3DS Mii Modifier and there is that FixCRC application , but it crashes when i opened it ..

 

[Demnyx]

I found something :

<< It will show you a message CRC = XXXX. It won't show XXXX but it will show a combination of letters and numbers. Write this down and close commad prompt.

STEP 5: Switch back to HxD and press CRTL and G at the same time. In this window type in C81E.

So it is what i must do after creating a new mii and dumping the file ? It is what you intented to say when you said copy/pasting the console ID to the other miis ?

 

[Ryccardo]

It's very hard to explain if you don't know the format for the data of a Mii, here's an example (look at the non-selected part at the end): https://gbatemp.net/threads/mii-research-lab.421304/page-2#post-6461840

As you can see, they start with "03 0? ?? 30" (where the first number is 0/1 for copy enabled (blue face icon), the Others indicate position on page and page number...
Then the 4 next bytes are the system id, you must copy and paste them from a mii created on the console, to the miis created on the other
Then save the file and use fixcrc following that guide you found!

 

[Demnyx]

So , in your picture , the 0 is for copy enabled then 00 70 30 indicate position on page and page number and 00 00 00 00 are the system id ? That's right ?
And , how do I do to know where a mii's informations starts for copy pasting ?

Sorry , I'm very noob on that ...


EDIT : How to read in the table of HxD ?

For example i saw on 3dbrew that :

Offset : 0x0

Length : 0x4

=> Mii ID (big-endian 32-bit unsigned integer)
The most significant 3 bits determine whether the Mii is Special, Foreign, or Normal [1]
time_offset = (mii_id & 0x0FFFFFFF) * 2;
time_offset is the time the Mii was created, represented as the number of seconds since 01/01/2010 00:00:00

How to know where its situated ?

Thanks for helping



EDIT 2 : http://zupimages.net/viewer.php?id=16/27/sdr3.png


So , my Console ID is A7 B3 58 3B ? Right ?


EDIT 3 : I think i'm understanding , all bytes before the byte "03" are ignored right ?
So the offset 0x0 is normaly the offset 0x8 right too and the mii's information begin at the byte 03 ?

Thanks you again !

Please help.. i tried to change system ID of qr code mii and it didn't work. Or its because qr code mii haven't the same format than original mii ?

Yes! Assuming that Mii was created on the nand you want to import to!
Copy and paste it over every other Mii's system ID...

So the offset 0x0 is normaly the offset 0x8 right too and the mii's information begin at the byte 03 ?

The first Mii (personal one) starts on byte 8, yes, and they're 5C bytes long, then another one starts immediately!

Please help.. i tried to change system ID of qr code mii and it didn't work. Or its because qr code mii haven't the same format than original mii ?

QR codes themselves are signed, a Mii inside cfl_db (that may or may not have been scanned from a QR) isn't, so changing the system ID will work; did you remember to save the file, run FixCRC on it, and replace the number afterwards?

 

[Demnyx]

Thanks you for your informations ! I don't have the destination console yet , i just want to do some tests with my actual 3DS to see if it works

I will retry it soon , i think i did something wrong.

Thanks again lol !

EDIT : Just another question , what do " 5C " mean ?

EDIT 2 : The second QR Code Mii's ID end by 10, thats strange or not

EDIT 3 : Tried with another mii and it didn't work ... or we must also modify the CFL_OldDB.dat ?
And concerning the restoration method , what must i do ? I tried with extdata_dump as on the tutorial , and also with JK'S save manager (I just replace the CFL_DB.dat)

T_T

EDIT 4 : Also tried with someone's CFL_DB.dat , i injected it , created a new Mii , extracted it , replaced system ID , fixed CRC , BUT.............................. T-T
