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

The best you can do is to check the NCSD header manually with a hexeditor ... everything else is in gods hands.

Okay..... Thanks, i'll try!

Ok, so I suppose the NCSD header must be different between the unbricked SysNand and the bricked one, right?

just did this on an o3ds xl. worked great. thanks! n3ds is next

i just started it on my n3ds as i have nothing better to do, good luck.



god the back ups take so long with the 1.8gb nand

--------------------- MERGED ---------------------------

hmm i cant get decrypt9 to dump the emunand after tinyformat. keeps saying error, sd card may be full, there is over 10gb free on the sd card -_-

How do I fix this error while downgrading the emuNAND?

Yes, it has to be the same as the O3DS NCSD file that is included in the downgrade packs.

 

[pbanj]

got past the full sd card error by creating a Decrypt9 folder for it to dump into

flashing the downgraded sysnand fingers crossed and butt holes clenched

Good luck man!

ok it finished now the moment of truth.......
annnndddd................

[pbanj]

well i restored my nand, compiled the 3dsx and flashed it. all i have to say is wow it boots fast lol

Flash the stock/nonpatched TWL_FIRM before downgrading and it should work.

 

[Ronhero]

Has anyone had any success with a 1.2gb nand? I just noticed that when I make emunand on a 1.2gb nand it makes the emunand image 1.8gb. I am going to see if I can resize the emunand partition on the SD card to make it work

Edit: I got it to work by using EmuNAND9 to make a new emunand partition on the sd and D9 to rip the nand

Thanks.
EDIT: Thanks for all your help. Finally got my OTP.

 

[Zengath]

Managed to get my OTP as well. Thanks to all the people that made it possible!

 

[chizco06]

Just got my OTP from my N3DS, thanks for creating this guide couldn't have done it without it

 

[OrGoN3]

don't think it's a good idea at all , since even if you succeed to downgrade , how will you update back to 9.2 again?(updating with a gamecard will brick your n3ds)

Make a backup of your emunand and copy the files to your computer, for safe keeping. Downgrade emunand to 2.1. Extract OTP keys. Restore emunand or go on computer and restore it manually.

No. That's not possible because no cfw can run 2.1 emuNAND, so all you'll get for emuNAND is a nice black screen.

I'm lost. This guide is to show you how to downgrade emunand to 2.1, then to grab the keys using decrypt9, without having to load the emunand. What's the issue?

Hmm they might have changed the method of downgrading (highly unlikely), but from what I remember, you downgrade emuNAND, use D9 to extract emuNAND, do a little magic, and inject the downgraded emuNAND to sysNAND, and then you get your OTP. You say that you just downgrade emuNAND and get your OTP which would be unbelievable, but I'm pretty sure you can't.
