    I am writing this to help clear up a lot of misinformation that's going around regarding exactly what changed and how this affects the scene going forward.

    The system update 11.0.0-33 was released for both New and Old 3DS devices on May 9, 2016 in all regions. The official changelog can be found here and a 3dbrew page with technical details can be found here.

    Confirmed: arm9loaderhax users are safe to update SysNAND and EmuNAND / RedNAND.
    Confirmed: EmuNAND/RedNAND users are safe to update their EmuNAND / RedNAND (but never SysNAND!).


    Any user of the Guide (or Luma3DS + NTR firmware bin in general) will be completely unaffected by most of these changes since the NTR firmware bin replaces 11.0.0's firmware with a lower version firmware.

    The Changes (or Lack Thereof)
    Cubic Ninja [ninjhax]
    • Lost access to both http:C and soc:U, which means Cubic Ninja on any version 11.0.0 and above will no longer be able to download it's payload off the internet. This means more code must be squeezed into the space of a single QR code, but smea believes this is only a temporary problem and can be worked around given time
    • Received codebin physical-memory randomization which was originally added for the eShop in 10.4.0-29, which temporarily makes launching the exploit very unreliable until an update is released
    Ocarina Of Time 3D [oot3dhax]
    • Received codebin physical-memory randomization which was originally added for the eShop in 10.4.0-29, which temporarily makes launching the exploit very unreliable until an update is released
    Pokémon Super Mystery Dungeon [supermysterychunkhax]
    • Nothing
    VVVVVV [(v*)hax]
    • Nothing
    Super Smash Bros. [smashbroshax]
    • Nothing
    friends-sysmodule
    • fpdver was incremented once again, which means that once a server-side toggle is flipped (usually around a week after release of updates), users with outdated friends-sysmodules will be unable to play online
    svcBackdoor11
    • This function, which is used for many arm11 kernel applications such as BootNTR and RetroArch, was completely removed. This will temporarily break applications that use it unless you are running the latest Luma3DS commit
    "svchax" (aka memchunkhax2.1)
    • This was not truly patched once and for all, but has had some complications introduced
    • New security checks in kernel heaps were added which makes "svchax" require extremely precise timing and trickery to execute, breaking it (possibly permanently) unless a fix is implemented
    • Downgrading in general, regardless of any arm11 kernel exploits (like svchax) released in the future, has been broken (possibly permanently). The firmware now contains a hardcoded list of minimum versions, and will not let us install a system title of a lower version than in the list, even if we have permission to install our own titles. This will make downgrading on 11.0.0's firmware impossible if no software workaround is found.
    • Currently, there is a hardmod workaround to flash an older firm to NAND and re-enable downgrading, but this could possibly be fixed in 11.1.0 and it's only fortunate that it hasn't been fixed yet.

    Thank you Plialect :) You've done a great job for the community with your guide and this post cleared up a lot of confusing about the new update. It would take quite some time for people to buy 11.0 stock devices but for noobs who don't know and update it can be quite a problem to downgrade now..

    No downgrades from arm11 anymore. You can use an hardmod however.

    Titles are signed.

    No, not without getting Nintendo's keys as arm11 can only install properly signed titles, whether "legit cias" or system titles. Downgrading could be done through an arm9 exploit though.

    This is a very nice guide as most (myself included) probably did not know about the minimum version checker (which will sadly probably break downgrading for a while). Good shit, keep it up!! :bow:

    @Plailect add in Emunand Downgrading from 11.0 is possible with a lower ntr firmware.bin, I can confirm this.

    I believe Ive caught a case of dyslexia in my sleep, thats 4 times today ive misread something.

    Also i followed the guide today and had 9.2 to 2.1 fail on me 5 different times. I eventually went and updated to 11.0 to get the 2.1 downgrade to work.

    9:08 PM <@yellows8> Plailect: anyway, smash is not mentioned on the v11.0 page at all.
    9:15 PM <Plailect> I just wrote what tux said tbh
    9:15 PM <Plailect> he linked that and said it was patched; I didn't really look at it
    9:16 PM <@yellows8> what page was it?
    9:17 PM <Plailect> the memory management page
    9:21 PM <@yellows8> versionlist update is just some JPN title(not hax related).
    9:22 PM <Plailect> oh
    9:22 PM <Plailect> probably should have verified that...
    9:22 PM <Plailect> my mistake then, I'll edit

    Does this mean we can't get the OTP anymore?
