    Safehax by TiniVi
    https://github.com/TiniVi/safehax

    This new exploit will allow you to downgrade without the need for DSIWare or another CFW 3DS.
    CURRENT SUPPORT: 11.1/0 (Waithax)
    FUTURE SUPPORT: 11.2 (Waiting on Fasthax)

    DISCLAIMER: I didn't create Safehax (He finished an hour before I had started) I just thought this would help out

    Background
    A few days ago 3DS Brew was updated with a new exploit. It has been implemented already but bugs are still being worked out. We are currently waiting on fasthax implementation for 11.2 support but it works on 11.1 & below.

    Didn't see any mention of it on this board. (Plenty in the homebrew section) Thought a proper thread would be in order.

    HOW IT WORKS
    Firmlaunchhax is the arm9 exploit people use in 9.2 (Works up to 9.5), but you need arm11 kernel access to patch some of the arm11 kernel function calls for the exploit to work.
    https://yifan.lu/2015/01/17/reversing-gateway-ultra-stage-3-owning-arm9-kernel/

    There is another version of the firmware called SAFE_MODE_FIRM that is used by the system updater where firmlaunchhax has not been patched. So the idea is to boot into this firmware run Firmlaunchhax then downgrade using the ARM9 access we now have to 2.1 and install A9LH.

    TLDR; THIS IS A ARM9 EXPLOIT

    HOW DO I USE IT
    https://3ds.guide/decrypt9-(homebrew-launcher)

    Q &A
    Is this safe - Probably the exploits are not new, but you should wait for the guide.
    Does this require DSIWare - No
    Can I downgrade 11.2 - Not yet, as soon as fasthax is implemented you will be able to.
    Can I downgrade 11.1/0 - Yes using Waithax -> Safehax
    Does this work on all consoles - Yes
    Can I install A9LH - Yes
    Do I need to downgrade to 9.2 - No, that step should be redundant as we now have ARM9 access on 11.2

    Thanks for the hard work, I would also strongly suggest waiting for a guide on the HOLY website since not many tests have been conducted yet

    If you're have a N3DS, you could try to run OTPless a9lh installation directly. Once sighax will be out, no more downgrades for o3ds users too!

    Hardmod users: id recommend you to test first other than other users. If you want to.

    You can test if you have 11.1/0 or lower. Though I think the Luma patches cause problems.

    Users with Corbenik is used for this. As Luma has the patches pre-built in.

    Wait for fasthax in the coming days!!

    There is no stable builds as of right now, your "working" isn't exactly stable as it's probably compiled from the alpha release
