OTP Guide

mashers · Feb 17, 2016

I'm having a problem with the command line stuff with the bricked emuNAND.bin. I've got 3DSFAT16tool, emuNAND.bin, nand.fat16_0x4_.xorpad and nand.fat16_0x5_.xorpad all in the same folder. Here's what happens when I run the command:

Code:

./3DSFAT16tool -d -n emuNAND.bin ctr.bin nand.fat16_0x5_.xorpad

3DSFAT16tool (C version) by d0k3
--------------------------------

dumping & decrypting emuNAND.bin
from -n
using ctr.bin

open ctr.bin failed!

Any ideas why this is happening?

basically, yeah... we'll still need something like pasta to boot sysNAND from a9lh but ReiNAND already works with it

does arm9loaderhax already working/released?
is there an easy way to get the otp file on n3ds without downgrading? such as using decrypting tools?
im afraid i might get bricked on the process of downgrading...

yes it's been sitting on github for quite awhile ( https://github.com/delebile/arm9loaderhax ). Unfortunately, there's no easy way without a downgrade, sorry

Yes. https://github.com/delebile/arm9loaderhax

If there were any easier way to get it, no-one would be downgrading.

Wait, I reformatted my sysnand and SD card after dumping the xorpads... Do I need to dump them again due to formatting the sysnand and SD card?

Hey, just letting you guys know:
- First and foremost, I know what I did was stupid, however I was going to hardmod my 3DS eventually so to me it doesn't make a difference. I went into this knowing I was riding on a slim chance, and more likely than not it would brick (either by chance or a dumb decision)

I downgraded to 2.1 successfully, and successfully dumped my OTP, though I soft-bricked my 3DS by updating to 6.1U via Pokemon Y.
I get an "Error has occured" on startup, and recovery mode won't work. What does this mean? If you don't have the time/money to hard mod, you should wait for a stable process. I knew the chances of me bricking were high, but it wasn't a concern of mine as I honestly love tinkering with my 3DS more than I do playing with it.

tl;dr, don't update via pokemon (on New 3DS), bricking will ensure.

TBH with what I've seen, this should only be attempted with O3DS (not 2DS) with gamecart with update 4.x to 6.x, if you don't feel/want to hard mod it, and you feel like dancing with the devil for a bit.
Otherwise, you should stay away (especially since we might be able to get the OTP hash very soon...)

There are reports saying that upgrading with pokemon would work... this shit is getting very cofusing

Very much this.

Only reason I felt ballsy is because I want to tinker with homebrew and some of the things I want to tinker with will probably end up bricking me anyway, so the hardmod for me was a yes or yes, question was when.

Yeah, it's the only reason I decided to try. It may have been that I was on a Frankenstein firmware, or by pure luck. Whatever the case, just know it's not 100% secure.

Nope, recreating the xorpad made no difference. I'm still getting "open ctr.bin failed!" when I try to run the 3DSFAT16tool command

Try running cmd as admin or disabling UAC

Run just "./3DSFAT16tool" and tell me the output

Do not do ANY cart upgrade on a N3DS. That's pretty much as simple as it is.

This will no longer be needed soon. As is I would recommend against it.

So, currently what is the method to upgrade n3ds when we are in 2.1.0 then?

Xenon Hacks · Feb 17, 2016

@Plailect So I'm attempting this again and now the 3DSFAT16tool step works but this

3DSFAT16tool.exe -d -n emuNAND.bin ctr.bin nand.fat16_0x5_xorpad
3DSFAT16tool.exe -i -o emuNAND.bin ctr.bin nand.fat16_0x4_xorpad
move emuNAND.bin sysNAND.bin
del ctr.bin

is incorrect it should say this

3DSFAT16tool.exe -d -n emuNAND.bin ctr.bin nand.fat16_0x5_.xorpad
3DSFAT16tool.exe -i -o emuNAND.bin ctr.bin nand.fat16_0x4_.xorpad
move emuNAND.bin sysNAND.bin
del ctr.bin

im using the N3DS with Cubic Ninja tut.

Devs have a browser hack working that boots decrypt9. Not public as of yet.

AHA! Disabling UAC would mean rebooting my Mac IIRC, but doing it through administrator command prompt in a Windows VM worked! Thanks buddy!

It's working now, but thank you for the reply. To answer your question though, it just provided the syntax information for the command.

Good luck, the nail biting moment has still to come!

Interestingly though, it seems everyone doing it on N3DS so far has had the process go fine. We've not gotten a big enough survey base yet, but so far most bricks seem to be from trying to upgrade off of 2.1, not the downgrade itself.

Well, since I've got a hard mod the worst I have to fear is wasted time and minor inconvenience
