    It probably sounds strange coming from me, one of the first people who dumped the New 3DS OTP, but I have a question about how to dump the OTP using the standard techniques.

    In the "standard" instructions for dumping OTP on an Old 3DS, there is this step:

    This step I don't understand. When you're running something from EmuNAND, won't sysUpdater be unable to update the FIRM0 and FIRM1 partitions? Like, for the reason that it warns you not to run it under a CFW.

    I don't know how to install or run a CIA without a CFW, so I don't see how this possibly works.

    They are written later in a python script I think to the emunand image

    the problem is, once formatted with tinyformat, you have to find a way to install a cia manager, cause everything is gone

    A. You have Gateway, easy, you boot into CFW with GW (have Devmenu on Gateway SD as .3ds) and launch menuselector and select Devmenu
    B. You inject FBI into Health&Safety app
    C. You boot into HBL from CFW with Cubic Ninja or Zelda OoT and install a cia manager with FBI or NASA or another hombrew cia manager

    and it's not update, its downgrade, also on O3DS you don't need a python script to fix emunand.

    Emunand 2.1 on O3DS isn't bricked, you can just flash it to sysnand afterwards without running it through any script to fix it like on N3DS, that's why getting OTP on O3DS/2DS systems is so damned easy and almost without a risk to brick. (unless you have a K/C/T 3ds)
    (Got OTP from 6 O3DS systems and 1 2DS)

    [EDIT 1]
    Maybe i understood wrong :P

    But here's what i understood from all the chatter about sysupdater:
    1. Sysupdater running from HBL doesn't work for downgrading (not enough privileges)
    2. You need to install sysupdater as cia, cause the cia has more arm privileges then the .3dsx version

    [EDIT 2]
    And i preffer the guide without Cubic Ninja (i do have CN), and the reason is
    I don't like reflashing CN constantly. it's just easier to go to the url and get the OPT.bin that way

    The warning in sysupdater are geared towards gateway (aka brickway) and other CFW that boots sysNAND with firmlaunch

    EmuNAND is fine it's not touching your sysNAND so if anything goes wrong you restore a backup

    I don't get how you can run sysUpdater as a CIA, though, without some sort of CFW running, but sysUpdater has a warning that says that it'll brick your system if you're running a CFW.

    I understand why sysUpdater doesn't work from Homebrew Launcher; no access to am:u.

    The internal details of the 3DS are easier for me to understand than the end user techniques to accomplish tasks.

    Don't they all boot using firmlaunchhax?

    The Old 3DS in question is NAND-modded and has a backup, so bricking SysNAND isn't a worry anyway. In fact, it'd be less of a hassle to just do all this on SysNAND.

    No for example mini pasta loaded from HBL can run it safe and with rxtools devmode/pastamode

    Those reload the system using without redirecting the sysNAND firm and add reload patches.

    Instead the current load FIRM has sig checks patched that's all

    I did 2 systems straight in sysnand, yes it's easier, bit more risky, but (both where hardmodded) if hardmodded you always have a return :)
