    a installed legit cia will stay installed if you revert to OFW and will work.

    the only way to get a legit cia installed on OFW currently is by a system transfer (which will copy the legit cia over), or buy it. Pretty sure you can install legit cias onto a cfw system, then system transfer them to an OFW. This way you can get a OFW 3ds with all legit CIAs.

    nope, system transfer will not transfer legit CIA games to the next system, despite them being legit signed as far as the 3ds itself is concerned, the way the transfer works nintendo will regenerate tickets for the target system, and it will not generate replacement tickets for mismatched legit CIA files, if the console came with the game installed already from the factory (i.e a console + game bundle) it will transfer correctly, but if you install it yourself it will not

    so just have to hack, install, then unhack to get a complete legit collection.

    i still wonder how they know the difference between a pre installed one that was originally there vs a pre installed one that was dumped with cfw and installed elsewhere with CFW.

    they seriously actually track which systems have pre installed universally signed games on them? i thoguht the entire point of universalyl signed is that its' the same binary on all of them.

    I wonder. coudl someone make fbi.firm, boot it with ntrboot, and use it to install legit cias?

    well i would imagine they would just assign a serial range to each game for their database i.e XX00002-XX99999 = Mario Kart bundles XX900000-XX909999 = Mario 3D Land bundle etc, but for the purposes of expediting the install process in the production line they can just install the same image across all consoles else they would need to have each ticket generated per console which would probably complicate things

    as for installing the games, you can use NTRboot to boot into Luma as a one off and install the games via the home-brew launcher with FBI

    may i just summarize it all? so, get cfw, use FBI to install the legit cias (i recommend using *snip*), after you installed all of the legit cias you want for free (i want miitopia,tomodachi life) you could unintstall cfw such as arm9loaderhax, luma3ds and godmode9 etc, and after its in its original firmware, the icons will still show the game, but how would i still play it? :( im sorry for asking too many questions...

    I'd dump the save with checkpoint or something just in case. but if the demo saves, the full game probably has a routine to load demo saves, so it should import it automatically.

    You have to die before you can wake.
    thank you.
    that's what i thought, but it didn't answer my question, but, Quantumcat liking your post did confirm this for me.
    i knew that.. honestly,
    when i read:

    "If you decrypt the contents and edit the game"

    i literally read,

    "if you decrypt it AND edit the game, by doing the following."

    not "you change the signature if you JUST decrypt it."

    wording is important when it comes to technology :D

    i suppose its common sense,

    if a game comes from the CDN, its going to be encrypted. any change to its current structure would change the code, and nintys sigg wasn't applied to an decrypted game, therefor breaking the signature.

    Wording cearp....wording ;)

    Decrypting needs to be its own line.

    I want to install own CIAS with hacked roms with working wireless functions. I hacked Gold Silver and Crystal. I tried to edit Crystal CIA. I discovered that the rom is uncompressed and can be overwrited in easy way trough the hex editor, but the hash don't longer match and FBI don't complete the installation. How I can fix it to install it with FBI? I tried to repack a new CIA with my hacked roms but I can't find .PATCH files with the wireless functions...
