Homebrew ARM9Loader -- Technical Details and Discussion

[DjoeN]

It's a 64GB Class 10 Lexar. Sysnand boots in around 10 seconds though. Currently using 10.6 Emunand with AuReinand (o3DS XL if it's of any relevance).

Emunand 10.6? did i miss something?

[EDIT]
Yes i did miss it
10.6 it is now

Screen stuff is going well, bilis fixed the top screen and I fixed the bottom screen... still needs backlight but that's all that's left...
look carefully you can read the text onscreen

Spoiler: Image

backlight is next on the list

Nice work @dark_samus3 by both you and bilis

There's any procedure right now for uninstalling a9lh? (just curious)

I can't imagine why anyone would ever want to uninstall it.

After the numerous Compiling request and help Post and threads I've decided to create a Simple Google Slide/Form to just take Name and OTP dump from Link, If people would like to volunteer to compile the arm9loaderhax 3dsx then Return the file to the requester, send me a PM and I will add you to the Sheet, when there are a couple of people volunteering then I'll make a thread for it, if there aren't volunteers the sheet will just be closed. Current Link to Pre-Submit Compiling Request: Google Form

Updating the boot code because there's a (hypothetical) hard-bricking bug, for example.

my (incomplete) version of the a9lh-installer can install each payload separately so updating a payload is as easy as running my installer with the payload on the SD card

Going from delebile's a9lh to your version still requires an uninstall, right?

nope, just compile the installer and install away

 

[Urbanshadow]

Then I will keep an eye on you, if you don't mind.

I don't mind repo is here https://github.com/dark-samus/arm9loaderhax still needs some work and has potential brick risk if all of the payloads aren't on the SD card

Even if you got rid of Emunand and boot AuReiNnand A9LH in sysnand 10.5/10.6?

I suppose you need to boot into Emunand (with Firmware90.bin) with HBL support

Yeah... I have a feeling arm9 hooks will become a thing very quickly now that everyone is forgoing emuNAND

I like where we are going, but I feel like we should center on the otp grabbing part rather than being carried away by the excitement of new posibilities.
We can't say it's safe to go without hardmod.

the OTP guide is about as safe as it gets really... automated script that modifies your NAND for you and all that, doing the downgrading in emuNAND to negate risk on sysNAND and, thanks to bilis and gelex, otp and decrypt9 from the browser on 2.1... doesn't get much better

So we need homebrew that can run under those circumstances, Maybe a cia installer that works under A9LH sysnand would work to update A9LH

What arm9 hooks let us do is run any arm9 payload (decrypt9 emuNAND9 or any CFW) from higher firms that have been patched

Well, we could do a nand validator script to check the backup's healthy state, and perhaps we could nail down what groups of titles on 2.1 contain the otp bug, to try to achieve chimeric downgrades instead of the full system and reduce the impact... gee, idk.

the title is NATIVE_FIRM... and since the titles check the NATIVE_FIRM version and refuse to boot in certain conditions we can't run 2.1 NATIVE_FIRM with the newer titles

At this point I feel like downgrading to get the OTP might even be safer than downgrading from an unhacked console to 9.2 in the first place. In the case of the OTP downgrade you perform most of the dangerous steps in an emunand environment and so everything really should be in order by the time you flash anything to your sysnand.
