Full Guide Release!

https://plailect.github.io/OTP/

All regions now supported!

If you appreciate this guide and the work I put into maintaining it, I accept donations through both Bitcoin and PayPal.

If you felt like the guide helped you out then I'd really appreciate it! If I get enough I may buy a 2DS for testing hardware stuff so I don't break another N3DS.

If the guide didn't help you out then I'm really sorry about that

Just out of curiosity, is there a way to remove A9LH?

 

[Mrrraou]

Just out of curiosity, is there a way to remove A9LH?

Yes: restore a NAND backup.
Or more complicated:

1. Restore the FIRM partitions to make them match your firmware on sysNAND
2. Restore the keysector
3. (Optional) Clear the 0x5C000 sector

Boot into 9.x sysNAND (probably with AuReiNand's 9.x FIRM mode) and then use Decrypt9 to restore a NAND backup from before installing it.

Thanks! And is the brick rate higher or lower than using julian20's latest sysUpdater build to downgrade to 9.2?

Totally unrelated, because the latest sysUpdater build to downgrade was using an unstable Kernel11 exploit.
Here, the only issue should be the user doing something wrong.

heya, now this comes with no guarantee or anything, i had to tweak it as i went along due to case sensitive stuff and the o3DS side of it is completely untested, it was also based around the original guide, but this is a completely automated (on the computer side of things) OTP dumping except for hitting any key after performing the steps that require interaction on the 3DS, there may be errors/bugs i missed but just figured i would share it as it may help some people, feel free to improve on it as you see fit

PS it doesn't include the Firmware files so they will need to be provided by the user, i was also going to include reinand but didn't due to it including firmware files, so it should all be allowed on gbatemp what is in there all the end user needs to do is use their CFW of choice and put the update files into /copytosd/updates

let me know how you get on if anyone uses it

Pretty nice bat
I did almost all the same but without a bat , maybe ill try to use your bat with my next O3DSXL i'll be getting OTP from

Is there a way to know if your dumps are good? CTRNAND, ...

No, not really/yet, or at least, you can't know that until someone does a really complete thing for it.

That's what I like to hear! Maybe I'll do it first on my O3DS (even if it has no uses now), then on the N3DS. This will be a good excuse to learn how to compile as well!

how to compile 101 (on Windows)

1. Install devkitPro + devkitARM
2. Install Python 2.7 x86
3. Install PyCrypto 2.7 x86
4. git clone http://github.com/delebile/arm9loaderhax
5. cd arm9loaderhax
6. make

Does it matter if I leave my 3DS charging during the entire process of downgrading to 2.1 and dumping OTP?

It shouldn't. I did it just to be sure that it wouldn't lose power.

If you don't close the lid, it should be all fine.

It's a bit confusing that the DG process needs Python3, while compiling needs Python2.

 

[hackotedelaplaqu]

Must be an issue with your payload. Try using AuReiNAND.

x1000 thanks ! Welcome to arm9loaderhax master race !

If my tablet is 64-bit, I should take the x64 installer of Python, right?

 

[Mrrraou]

Take the x32 one. It's better, I think. And some people got issues building it with the x64 Python.

 

[daxtsu]

I personally used 64-bit python 2.7, but it never hurts to stick with 32-bit stuff for consistency with others.

 

[hackotedelaplaqu]

Just to let you know, on python steps, I had to set up manually variable environment PATH.

 

[ihaveahax]

I used 64 bit Python 2.6 on Windows and building a9hl worked fine each time.
