    I read the newbie section, and this is not a question about downgrading a 9.5+ N3DS

    I want to know if I add a Firmware Flash Port to my 9.0.0-20U N3DS can I:

    Use my Gateway and create a 9.0.0-20U sysnand backup
    Verify it 10x (just to be sure) then:
    Update the sysnand to 10.2.0-28U
    Go on to eShop and buy some games
    Downgrade the sysnand back to 9.0.0-20U
    Create .CIA's of the eShop games on the SD card

    I know how to make .CIA's from eShop already, and was doing this until they locked up eShop from my reinand 9.5.0-23U emunand+FreeMultiPatcher a few days ago.

    Also I know how to remove the "crypto" from eShop Games with it added.


    Am I not seeing something - or would this work?

    Use HANS.. And yes, you can make cia(dump ticket.db) from 10.2 nand backup since you can generate xorpad for your 3ds's FAT16 partition.
    Second question: search seed encryption

    Thanks for the suggestion, but that won't work for me :(

    I can't use HANS because my sysnand was never setup with a NNID, and with HANS you cannot add one. :( :( :(


    I'm thinking my only option is to use a Flash Port and update the sysnand to 10.2, add the same NNID I have on my emunand and then access eshop.

    I do this all the time with a nand mod. It's the only way to make crypto fixed n3ds eshop games

    Stupid question: If one buys a used 3DS, how can one tell whether it was hard modded or not?

    If someone who bought it opens the 3ds and sees the board, he/she will know.
    Even if you desolder and clean the board, trace of residue will remain.
    Sofeware-wise, no way to figure out.

    I don't understand why OP can't set up NNID? Is there anything I miss? Can he just use mini Pasta + free multi patcher and create NNID first? I never use 3DS much, I just set up CFW, homebrew, Free Multi Patcher so I am kinda dumb about HANS, Eshop usage.

    I tried to do this using Gateway sysnad boot with FreeMultiPatcher

    I can get into eShop no problem (no nag to update)
    But as soon as I try to download something so it will ask to create a NNID, I get 007-2404 error :(


    Update:
    Tried Pasta with FreeMultiPatcher = same 007-2404 error :( :(
