Just curious, what exactly do you mean by this?

The fact that i didn't find myself the method to init lcd, neither i have written the code.
So i'd just like to know if the ones who did this would like it to be added to the public a9lh setup, with their credits.

Ah, alright well the creator was mostly bilis/b1|1s, I helped a small bit (with the bottom screen framebuffer, which ended up needing reworking anyways). I'm currently porting (with his help) the init into the stage2 payload along with making some improvements to the installer

Is the brick rate high if try this with no hard mod?

Chop chop Mr Couldn't Sleep. haha

Well just for that I'll make sure this has a 3 day delay for release :3 haha jk

I'll be going back to my corner in #Cakey then....

@delebile it's fine by me, but the code that was passed to you is the shitty version. I recommend using the version cleaned up by @dark_samus3. I'm sure you both can work something out together.

Just a lurker popping into say thanks to everyone! I'm still holding off on doing this process but it sounds like the progress we need i

 

[Februarysn0w]

so you mean screen init? lcd init? issue will be slove soon? if so, it's amazing work thank you. the homebrew like decrypt9, emunand9 work on without 9.0 firmlaunch?
If I'm wrong please correct me.

Contact me with the proper version when you prefer

I was thinking a little bit onto the screen init news. Could we get D9 (or an equivalent tool) loaded at boot time? (Before kernel?)

Some people suggested that it could already be done, but you're just blind without the screens.

Yes, but loading it that early means (at the moment) it can't decrypt or encrypt.
That means full NAND.bin, but no partition dump/inject or basically anything else, at least until a workaround gets going.

And even if there's such workaround, messing with sysnand in a9lh runtime sounds scary.

if that's because it loads so early that the keys aren't even loaded into the security system yet, shouldn't it be trivial to make an a9lh key dumper? Then a bit more code for d9 to use the dumped keys?

Just do encrypted CTRNAND backups.

A payload could setup the keys.

Theoretically D9 might be able to load a FIRM and get keys, just that it's something it'd have to do that it doesn't right now.

I'll wait on the screen init update until there's screen de-init implemented into the CFWs. I've gotten reports that the screen init brings back the 3D bug for n3DS users. So I'ma hold off on it for now.
