    I am downgrading my friend's N3ds from 10.2.0 to 9.2
    I want to back up his sysNAND before I start just in case.
    I have the latest Homebrew Starter kit and have successfully installed menuhax 2.2
    What's the best method for dumping the sysNAND?
    I tried the latest version of Decrypt9 and Emunand9 and when I launch either from HBL, the bottom screen turns red, black and then right back to the Homebrew menu.
    Can someone give me some guidance here?
    Thanks!

    Think I figured it out.
    I don't think it's possible to dump >9.2 without a hardmod.

    It's still not possible to backup your 3ds without a hardmod on >9.2 without a cfw. Unless you were linking them to the guide on how to downgrade?

    You are corrct, only way to backup your nand on 9.2+ is via hardmod, just follow best practices and format the system prior to attempting the downgrade, worst case scenario and you brick you can use recovery mode to update to 11.0.0 and get a hard mod to downgrade again
    That guide is like thread spam at this point, any thread about any issue will have that guide posted at least once......i wonder if its reached the other sub forums yet XD

    Dont get me wrong its a good guide. Its just thrown about with zero explanation, often with no attempt to see if its actually relevent to the question at hand

    Thanks. I took your advice and formatted the system prior to downgrade. Latest version of sysupdater did not seem to work. First it kept failing to load . Then I kept getting an error. Something about failing to get CIA file info. Ended up using safesysupdater and the downgrade was successful. I was extremely worried about bricking my friends console after all the trouble sysupdater gave me.
    I used sysupdater previously on my own N3DS without incident.

    The wiki has less description of dealing with frankenfirmwares & factory >9.2s.
    They have unlisted problems.

    Actually factory >9.2s can be recognized as frankenfirmwares.

    For example
    - Factory 10.3.0-28J can't read Ninjhax QR - it responses error and force restarting, but Internet upgraded 10.3.0-28J can.
    - Factory 10.3.0-28J will pop an ERROR and Blackscreen when the downgrading proceeds NATIVE_FIRM, but Internet upgraded 10.3.0-28J passes it successfully.
