Hacking Luma3DS - Noob-proof 3DS Custom Firmware

[wiiuser2]

Hi I upgraded mine A9LH O3DS XL from ARN 4.1 to Luma3DS 5.4 using this upgrade guide here:

https://github.com/AuroraWright/Lum...ade#upgrading-from-arn-43-or-older-to-luma3ds

After upgrading, I did the initial setup, and check marked "Force A9LH detectection" and "SHow current NAND in System Settings".

All works as intended (1st emuNAND boots by default, sysNAND boots by holding L, 2nd emuNAND boots by holding B)

But none of the payloads works (just blank screen with backlight on), I have named them all in the newer format and I guess I no more have to hold L key with the payload key anymore.

Kindly let me know what went wrong, why none of the payloads work. I have start_d9.bin (Decrypt9), x_emund9.bin (EmuNAND9), y_uncart.bin (UnCart) in the luma/payloads folder.

Are you sure you use the latest versions of the payloads?

No, I just renamed them... but none of the payloads works. I will try replacing them with new one right now.

EDIT: Thanks! Using latest payloads for each worked. One thing I noticed that for start button payload you still need to hold L key for it to work.

Sorry if this is a stupid question, but does luma3ds have loader.cxi support?

Anyone?
EDIT: i dont even know if it's loader.cxi or injector.cxi anymore

I think not. you have to modify source code to patch it.

Ah that's such a shame. Might look into something else then, Thanks!
edit: actually, i saw a ton of stuff about it much earlier on in this thread, if someone that knows for sure could comment that would be teriffic

Following the guide for region changing and using eShop on O3DS XL for Luma3DS

https://github.com/Plailect/Guide/wiki/Region-Changing

I tried it for 2nd emuNAND (although the guide is meant for sysNAND)

System stock SecureInfo_A is EUR in emuNAND whereas SecureInfo_C is JPN in emuNAND (changed according to guide)

Apparently Luma3DS doesn't seem to read SecureInfo_C on boot from 2nd emuNAND, so it is using stock SecureInfo_A

So it shows English language with black boxes (because I deleted those titles), instead of the JPN language and titles as intended

Alternatively, using modified SecureInfo_A to JPN and opening JPN eShop does not work, it gives error 005-4270 first, then error 007-2670, and then error 007-2001

Is there anyway to force read SecureInfo_C on 2nd emuNAND using Luma3DS?

Iirc it does, its how its doing the ver change in system settings and I think a few other things.

oh , safesysupdater !? that sounds easy enough , i shall try it later on thank u.

edit: any U.S version of 9.2 emuNAND is fine yes ? (from the iso site)

edit1: and ooh , i almost forgot , so if i use the sysupdater app and then install the 9.2 emuNAND downgrade cia files will that automatically downgrade emuNAND and not touch sysNAND yes?

so steps for me with updated sysNAND only would be these v

1.creating/restoring a backup of my emuNAND (my backup is a 10.x fw)
2.download the U.S emuNAND 9.2 update cia files put them in updates folder on sd card.
3.use sysupdater and install the cias off updates folder.

yes?

Why not just restore SysNAND_original.bin to your EmuNAND? Already unlinked, and already on 9.2. You restored EmuNAND to SysNAND. If you restore it to EmuNAND as well, your NANDs WILL be linked. So you will need to run TinyFormat.

 

[proflayton123]

Yes just make sure the 9.2 files are the right ones for your system. When you run the downgrader from emunand it downgrades the emunand not the sysnand.

I'd say use PlaiSysUpdater than 'Safe'SysUpdater personally

I've used a previous version of the region change manual to create an EUR EmuNAND (SysNAND is USA) and am using a 'public' EUR SecureInfo_A; by editing your own don't you invalidate the RSA2048 signature, or is the whole idea that Luma patches any SecureInfo_A checks?

It patches those checks, but if you ever go back to a "clean" environment without sig checks being disabled, the system won't boot without an untouched SecureInfo_A, of course. On a stock system with no emuNAND or A9LH that would mean it'd brick effectively (assuming one was silly enough to flash it to an unprotected sysNAND like that).

Sounds good! Can you remember how to do it?

git clone --recursive luma3ds

edit the source of the loader

 

[Ramzh]

I just want make sure about one thing, can I restore the sysNAND 9.2.0-20E (no A9LHAX) with D9 to have a clean 9.2 and then I after I finished working on this firmware go back to sysNAND-A9LHAX with D9 and Luma CFW?

 

[Yudowat]

git clone --recursive luma3ds

edit the source of the loader

What code should I change?

@Aurora Wright , for double posting, but can you or anyone answer me from here?

Just use this http://luma3ds.ericchu.net/

 

[Razor83]

@Aurora Wright Would it be possible to add an option to show the SD card space in MB/GB instead of Blocks in system settings?

Use FBI to show that

But that doesnt show the remaining space in system settings.
I would like to make the 3DS system settings match the Wii U's which displays space in KB/MB/GB.
