Yeah, I read al9h boots the payload so early the screen didn't even init yet. No idea why people want to reintroduce the bug by getting screen init (unless we are fixing it in the process?).

So boot managers (and also CakesFW) can work. I'm sure the screen init process is reversible (if it wasn't, services like gsp::Lcd on the 3DS OS wouldn't be able to turn the screens on and off), it's just a matter of figuring out how to do it, if different values are needed.

wtf ? what brick protection ? which d9 ?

Absolutely not... We trade the little 3D bug (that can be fixed by closing the lid for some seconds) on N3DS for a screen init from a9lhax, which means we can have for example the CakesFW menu from arm9loaderhax.

And this isn't released yet.

Thank for confirming my beliefs.

I hope a branch of a9lhax is created for New3ds that doesn't have screen init (that is until a time comes when when the 3d bug can be fixed without us having to close the lid for some seconds)

"some seconds"? it's literally just close, open, done, no waiting involved

The existing version of a9lh has no screen init so you're good there.

I got the screeninit version.
It's not going to be added to the installer yet because it has some cleaning up to do.

3D bug fixed?

Working on it. I think it's fixed but haven't tested.

How was it solved?

What is screen init and what can we use it for

screen init stands for screen initialization and we can get coding to work before our cfw starts up, like how cakes has it's patch menu that pops up before we boot into cfw.

How much does the screen init delay the boot times?

Ahh so it would allow for things like downgrade with both emunand and sysnand bricked?

As long as the parts of the nand that have A9LH aren't broken

Edit: I think

well right now if we tried getting D9 to run at screen init all that would happen is having a useless menu as we wouldn't be able to dump out sysnand or emunand bin files from what I understand.

you can dump and flash nands and i think some full partitions. but decrypting and injecting files is what doesnt work

How much does the screen init delay the boot times?

It should be negligible. Setting registers takes nearly no CPU time at all (though waiting for hardware to turn on might take a tiny bit longer).

Will the backlight turn on much faster then?

from what I was told that didn't work quite yet but something was being worked on

Faster than what? Booting OFW/vanilla sysNAND? I guess it would be a bit quicker in terms of when the backlights come on.
