    So now we almost have an ability to dump ARM9 BootROM which leads us to sighax - ultimate flaw that can be used to run CFW on any 3DS ever. And during 33c3 derrek said that we can use sighax to dump ARM11 BootROM. So my question is, what can we use it for? Is there anything new that dumped ARM11 BootROM does allow?

    A thread explaining it better than I can right here

    I wish I could explain it, but I really don't quite have enough knowledge to break it down.

    IIRC it can be used to get access to keys we do not have access to, or something like that :rofl2:

    Yeah,
    I know about sighax, I know that dumping ARM9 bootrom allows that. I'm more interested in ARM11 bootrom. Also sighax doesn't mean "full custom firmware" - it's perfectly implementable with arm9loaderhax as well. Read here

    how does one dump the bootrom . i know there arent public releases. but with some sneaky passages one could upload it and then magic finds its own way.

    I still stand by this claim. Since I am pretty sure I saw you could dump any 3DS keys from the Boot11(think it was called)

    inb4I get laughed at again :sleep::rofl2:

    You can make "Full CFW" or "True CFW" on A9LH. It's just nobody decided to make it.

    Thanks for an answer. Seems interesting, especially if we could use it to de/encrypt ROMs and CIAs right on the PC
