    Download this NNIDSave.bin file:
    https://www.dropbox.com/s/5g96tls1krt31n5/nnidsave.bin?dl=1


    Put it on the root of your SD Card.


    Run Decrypt9 from the Homebrew Launcher,
    Select "EmuNAND options" then select "File Inject" Select "Inject nnidsave.bin" it will ask you "if you wish to proceed, enter: <Left>,<Right>,<Down>,<Up>,<A>." it will then say "use arrow keys and a to choose a file" just press "a" to inject the "nnidsave.bin".once it is done it will say "succeeded!" then press start, reboot into emunand and create a new NNID. done!


    NOTE! If decrypt9 don't see the nnidsave.bin on your sd card, download this version of decrypt9:
    https://www.dropbox.com/s/he3769bubzmnb2q/Decrypt9WIP.zip?dl=1

    if you change your NNID, any content associated or downloaded with other NNID's will no longer work. that is highly recommended to backup your original emunand NNIDSAVE.BIN

    This is very useful! Especially in cases where people use system settings to format and separate the nands. With this, I can now direct them to remove the NNID from emunand, then add the same NNID again so that it's not problematic anymore.

    Back in the day, I had to make them backup emunand, use tinyformat, restore the backup.

    i know, when i first bought my NEW 3DS XL, the guy i bought it from had installed a CFW on it. it had HIS NNID on it and i couldnt really do anything with the eshop or even download updates for games because i didnt know his password and i no longer was in contact with the guy. so, for a while i didnt care but then i wanted to update some 3ds games and i found this so that i can reset the NNID in emunand without having to format or do anything else and finally update my games!

    Do i need a CFW for sure? No Gateway?

    P.s.: does the nnid stored into emunand dump?

    This would have been so much more useful to me if I didn't install a9lh.

    (turns out you just have to do it with sysNAND if you have a9lh but tread carefully obv)
