Hacking Removing NNID from a a9lh Console without formating

[Altairseven]

I'm thinking on selling my wii U with the games alongside the digital games i've purchease on mi NNID, the problem is that i have the same NNID in my cfw console with a considerably big amount of games installed (64Gb sd card)

My plan was to make a list of everything i've got installed and backup every savegame and then format and reinstall everything, but it would be an excrusiating amoung of work which i'm to lazy to do.

I've found this post from shadowtrance in a very old thread from early 2015:

Had this in my notepad from a while go, does the trick.


NNID is listed in: \data\<your unique id>\sysdata\00010038 > 00000000

It was pretty simple to do it and here it is how i did it:

1. I extracted my fat16 xorpad using launcher.dat from 3DS_Multi_Decryptor
2. Dumped emuNAND.bin using emuNANDTool
3. Extracted emunand.fat16.bin
4. xor'ed emunand.fat16.bin
5. Mounted emunand.fat16.bin.out with WinImage
6. Browsed to \data\<your unique id>\sysdata\00010038
7. Deleted 00000000
8. Renamed emunand.fat16.bin.out to test.bin
9. xor'ed test.bin
10. Injected test.bin.out into emunand.fat16.bin with HxD
11. Injected emunand.fat16.bin @ offset B930000 with HxD
12. Injected my new emunand.fat16.bin into my SD Card using emuNANDTool

Eh, voila, after booting into emuNAND NNID was gone

So, half those step can probably be done with decryp9 nowadays, and some of them i dont really understand,plus with all the advancement we had this year there must better way.

Mayby using godmode9?

Any idea would be appreciated, thanks!!

You can simply dump your nnidsave.bin, fill it full with 0's in a hex editor, then reinject it.
