    Shouldn't you downgrade if your firmware is lower then the one you're on? Think a slight mistake was made here :P

    Thanks for explaining these steps. This helped me out quite a bit. Only thing, my o3ds said I had to have my folder called "updates", not "update".

    That's because that's what the folder is meant to be named, OP has a few errors in the tutorial (See my post above for another one).

    Can I directly downgrade from 10.3 O3ds to 4.5 because 9.2 has so much poor download speed

    I guess it's time to move to 9.2 from 4.5.
    Thanks, I will try this out. Any suggestions what hbl entry point I would use on 4.5? Thanks!

    If you are doing it on EmuNAND, follow my guide. Else, use sliderhax (it has a low boot rate, so be patient) as an entrypoint. You can also downgrade to 4.5 with Gateway's Launcher.dat, but remove any cartidge before launching it.


    EDIT:

    There's no way to launch HBL on 9.0 and lower, but you actually can launch .dat homebrew from Spider (9.2 and lower web browser) Expolit. Just to remember, there is no .dat version of Smea HBL, nor a payload to boot HBL.

    Haha yeah, but the diff was I only need to go to dev mode on sysnand and that's it.

    This time, I'll try to update an emunand to 10.3. To try it out. XD

    Silly questions (?) before attempting a downgrade on my N3DSXL :
    1. How to safely backup my savegames ?
    2. How to keep a legit game that is already on my console ? (my Legend Of Zelda:ALBW legitely downloaded for instance)

    Yes. Use emuNAND Tool for backup/restore NANDs from SD.

    I know this thread is old but search and came to this thread.

    My question is this is used for downgrading or updating the emunand correct?

    So if my emunand is on 11 can i downgrade it to 9.6 etc...?

    Correct, though I can't really see any reason why you would want to.
