Homebrew [Request] CTRAging (3ds debug app) research.

[SomeGamer]

Do you know if it's possible to change the color of the LED without a physical hard mode?
IIRC, something like that is possible on wii

Only playing with the colors we currently have. So blue and red on the power LED and all colors on the notification LED since it's RGB.

 

[ketal]

So none in its current form? What would happen then?

You can change the internal configs as you please, but the changes won't be written unless all tests succeed.

That's too bad. I'm waiting so hard for some C-stick calibrator homebrew.

The C-Stick cannot be calibrated.
I don't know the exact reason, but I guess it's because it uses strain gauges to sense how hard you're pushing.

Well, for me a little push is enough to get it move upwards, but no matter how hard I try I can never get it move down for more than half a second.

I had that exact same problem, but only in one chapter of a specific game. Odd...

Many new3dses have this issue, making it hard to push the c-stick down or left. Nothing much you can do.
If you send your console to the support, chances are they will just replace the whole system.

 

[SomeGamer]

I had that exact same problem, but only in one chapter of a specific game.

I'm having that always, interestingly, my sister's 3DS doesn't have this problem. But her has wobbly screen, hard to adjust 3D and volume sliders which are all fine on mine. (What a rhyme!) Still, I wish I had a good C-stick. Another difference is that only mine has clicky shoulder buttons.

 

[PabloMK7]

Yes, if you manage to complete all the tests, which you can't because you lack the hardware and other system modules. Also, I think this dump has some slight corruption.

Nope, all the hashes match

You can change the internal configs as you please, but the changes won't be written unless all tests succeed.

Are you sure you can't disable test that doesn't work?

 

[Allahu_Spooky_Cena]

If anyone is interested here is a picture of the rgb led on the board.

And here is the hole in the back of the shell where the light shines through.

Why not attempt to edit the app to pass immediately? We don't have to worry about sigs or the app breaking.

 

[ketal]

Then we need the appropriate system modules.

You need to test your changes for them to be confirmed. Makes sense.

Why not attempt to edit the app to pass immediately? We don't have to worry about sigs or the app breaking.

..and possibly get an mcu brick out of it

 

[Halvorsen]

I don't think that all the test devices survived in the testing of a9lh or certain CFWs.

Do you remember the debug card AGING-NTR also known as NTR-EVA which had some tests for the NDS?

CTRAging, the 3DS equivalent to AGING-NTR, is an app used for testing the hardware at the factory, before it is approved for selling.
And after the tests, it uninstalls itself as well as other test apps, such as DevMenu.
However, uninstall isn't equal to fully deleted from NAND, that means:

YOU PROBABLY STILL HAVE IT IN YOUR FAT16 PARTITION OF YOUR NAND.

Great right!? Well.... no. Each time the console writes to NAND, it has a chance to overwrite it, because since it is no longer installed, the 3ds doesn't care about overwriting it. That means, the most used the system is, less probabilities to still have it in NAND. As stated here, sometimes only the TitleID is kept in NAND, other times its header, or nothing. I tried with my two o3ds, the first, which went throught many updates (5.0 to 9.2), didn't have it at all. However, my 2nd 3DS, which went from 1.0 to 4.5 with a card update (yes, I know I shouldn't have to update), only had the TitleID (000400000F980000) between a lot of FF.

If you want to try a working copy on your N3DS (O3DS crashes), you can go to pastebin and search for 3DS ctraging.

(29/05/16) The N3DS dump is working, it has to be launched from DevMenu. Video by @CrispyYoshi (thanks )



Holding START shows a menu!

Spoiler

So if you feel like you have a OLD 3DS which never updated, and hasn't been used much, you may be lucky. Dump and decrypt your fat16 partition and search for the TitleID, here it is how:

1- Use Decrypt9 to dump your nand fat16 xorpad.
2- (Dump your NAND if haven't already, the older the copy is, the more probabilities)
3- Download this tool
4- Place the nand file and the xorpad in the same folder as the tool. Name them nand.bin and fat16.xorpad
5- Run "run.bat"
6- If it creates a file called "000400000F980000.ncch", you may be lucky, put that file on your 3DS SD, run Decrypt9 and select NCCH Decryptor. If you can read "Exheader / Exefs / Romfs: whatever / OK / whatever" let me know

I have a pretty untouched backup of my o3ds on his factory FW, I will try to dump it tomorrow.

Sorry, but.. Does it matter I have A9LH installed?

No. It works the exact same way on my menuhax EmuNAND.

How in the world am I supposed to run Decrypt9 on 1.0 firmware?!

 

[SomeGamer]

There's a CN payload for that.

 

[SpencerlyEverly]

There's a CN payload for that.

I can't find the thread. Where is it?

The xorpad is constant for any given console and physical nand chip combo, so you could also dump with hardmod, update and cfw, then decrypt when you want!
