    Hello,
    I've found multiple things indicating how but they all don't see reliable to follow.

    Can someone point me in the right direction?

    I have a 6.x sysNAND and want to go to 9.2 for themehax.

    Thank you for any help!

    I just did it on my 2DS using the package on that ISO site (9.0.0 without MSET, AGB_FIRM and TWL_FIRM update).
    I used this to update safely. Just be sure to be in DevMode to prevent brick!

    AFAIK you need to run sysupdater in devmode which is avilable in rxtools 2.5 and 2.5.2. Also you need to download all applets via 3DNUS for proper region and make from them one CIA for sysupdater.
    Mahe sure you have working NAND copy in case sth will go wrong.

    Edit: You write better info @skidooelan.

    It is working on rxTools 3.0. Just be sure to use the 9-28 version.


    To @VashTS, check this thread this is where I learned how to do it.

    this worked great on 1 3ds...on the other one, for some strange reason it will not inject FBI!

    and i see the reason...there are 2 versions install on my sysnand for health and safety app, 1026 and 2051 but rxtools will only do 2051, system launches 1026...wtf!

    FBI injection can be a real pain. I suggest re-updating to 9.2 again to get a clean sysnand again, then try to inject the 2051 app/tmd via rxtools. Oh, and make sure you unlink your nands before you inject FBI, or you'll have to re-inject it after you format (I think?)

    yeah i got lucky - this 3ds was previously on 9.2, so was easy after i gave up on injection lol

    the first one i did was 6.xx so it was a necessity.

    i always do it this way on fresh 3ds'
    my raw 3ds,
    nand backup
    setup emunand (you can set emunand first, then nand backup so you save 1 round of 3ds to pc copy files)
    on that iso site, get the full pack 9.2 of your region and your 3ds (2ds 9.2, o3ds 9.2 n3ds 9.2 etc etc)
    copy updates folder to your sd
    setup rxtools, (either by gw mset via dg first or spider)
    inject fbi on emunand and sysnand
    run rxtools in devmode
    launch h&s app
    install sysupdater
    start update
    you're now on the tasty 9.2 fw
    optional:
    get starter pack for homebrew channel
    boot hc via spider ninj or whatever.
    install themehax
    rename boot_hb.3dsx
    get ctrbootmgr and copy files to sd

    config ctrbootmgr

    bam, 3ds with emunand, @9.2 coldboot via themehax
     
  11. You wouldn't need to, system format can't magically restore the original H&S app unless it re-downloaded every system app and re-installed them every time you did a system format. :P

    Wait, are you sure? I recall doing this one time while hacking a friend's system and the app completely disappeared from sysnand. During another session we managed to run a cfw and suddenly saw the app again. Isn't there some kind of signature checking or ID change that happens because of the format which would change the location of the Nintendo 3DS folders? (Or rather, is FBI run from that folder?)
     
  13. FBI, when injected into H&S, isn't in SD card. It's directly on NAND. Anything that changes in the SD card won't affect it.
    It disappeared entirely because it has bad signatures, so it won't load unless you have something which patches out signature checks (CFW)

    What happens is, either it disappears, or it appears but will tell you something's wrong with the software and to redownload it from the eShop.

    Oh, so it really was on NAND then. So, is the only way to recover from that either a flashcart or NAND restore?
