Homebrew ARM9Loader -- Technical Details and Discussion

[Shadowtrance]

Well, it's arm9 code execution on cold boot, even earlier than with menuhax, it's technically unpatchable, but it requires an OTP dump (which is what we're trying to get by downgrading to <3.0)

No no no. It's execute nothing on cold boot for me. lol

Lmao, good luck with getting it working

So there is nothing developed that takes advantages of this yet? Sounds like it's really useful! How does one go about acquiring the OTP?

haha yeah. no luck so far. No idea what's going wrong.

The screen won't turn on at all, if that's what you're looking for. If you get something to do a firmlaunch or force a shut down, that's usually a good sign.

https://github.com/delebile/arm9loaderhax This takes advantage of it... OTP is acquired through a downgrade to <3.0 and dumping using cubic ninja, oot3d or something else (a few people are working on that "something else" right now)

Right, but shouldn't the screen come on if a firmlaunch happens?

Alright but I don't get what arm9loaderhax does?? It just allows arm9 code to be executed on startup? I thought we had that already with CFW on 9.2? I have cubic ninja but how would I dump my OTP? As far as I see there is no application to even use...

Yeah, eventually it would screen init thanks to firm.

Yeah i realize the screens won't come on.
Just need something to actually run/show me some signs of life / that it installed ok (i assume it is installed ok as is turns on, unless it's some weird brick?).

Right, we do have arm9 code exec on 9.2.... this can be done on 10.5 (yep CFW on 10.5), it negates the need to use menuhax to coldboot into CFW, or use some other entrypoint (browser, cubic ninja, etc.) as for dumping your OTP, you downgrade to <3.0 and then use the QR codes (posted above) to dump the OTP

i uploaded the 2.1.0E title folder on that iso site for those interested in building a full firmware

Can someone confirm that oothax would work on 1.0 ?

 

[dankzegriefer]

Go do your own fucking work, leaker.

Your stupidity crashed my skull in.

You may leave now.

While I agree with you in theory, why resurrect a month old argument?

Wait, it was a month old?


Well... that was dumb of me, I forgot it was February.

oot3dhax won't work on 1.0 as-is (only supports 3.0-4.5), you'd need to port the ARM9 exploit to 1.0 yourself.

Then why not downgrade to 3.0? Wasn't the exploit patched the version afterwards?

 

[mitroux]

would a 3.0 system work to dump otp? if yes and you need a backup of 3.0 ods , i have one laying around
i need to know how to build cias from title folders , any help?

 

[Psi-hate]

Can someone give me a .sav for ninjhax1 for cubic ninja 4.5.0-10US? I for the life of me can't get CN to load the QR without crashing.

Do you have an internet connection?
