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

 

[haskell]

Can i follow this guide if i'm on 4.5? Which homebrew launcher may i use?

 

[Xinaman]

can i flash the unbricked emunand at 2.1 firmware to my emunand to ensure it boots?

no. there are no public cfw capable of booting 2.1 emunand

Hasn't been tested, but it *should* work.

Thanks. I think i'll update to 9.2 and then follow this guide.

Well, how can you unbrick without hardmod using this?

Once you have this you can use a version of decrypt9 that boots straight from arm9loaderhax. So assuming you did not overwrite arm9loaderhax as part of bricking, you should be able to restore a backup.

Okay, so, the arm9loaderhax works even when we get black screen of death, right?

Depends on what is causing it, but in theory once you have arm9loaderhax and the latest AuReinand (when set up right), AuReinand can block writes to the place where arm9loaderhax is stored. That should let you recover from most other bricks.

Okay, and it works only for Aureinand?

The protection against writing to the place where arm9loaderhax is stored? It is the only one I have heard using it, but I would imagine other cfws that are compatible with arm9loaderhax will adopt it. (you can see a description of the feature at the aureinand post: https://gbatemp.net/threads/aureinand-n3ds-o3ds-a9lh.411110/)

restoring sysnand and shitting bricks...

Edit: OTP dumped and everything is restored and working as before! thank you!!!

 

[FIX94]

just wanted to say thank you for this guide, just got my o3ds all done with otp and a9lh and now the instant I power on cakesfw fires up and loads emunand.

You should use AuReiNand and boot straight into sysNAND.

Booting sysNAND from ARN doesn't provide any real benefits beyond making virtual consoles easier, and it is needlessly risky.

fite me IRL

There's no risk becuase I can boot emunand if I hold L and restore everything.

lol, who said I'll stay with cakesfw? it was what I used before with menuhax for quite some time and I just used that to see if a9lh actually works

 

[PixelBurst]

Performed this on the other halfs O3DSXL now as well as my N3DS. Guide couldn't be more straightforward tbh!

Edit - and a friends O3DS.

 

[fr3quency]

Amazing guide. Finished in under 2 hours(lots of backups xD). Now it's compile time.

 

[Tigroid]

lol, I think I've seriously screwed up my N3DS. I made it through section 2, and when I booted up my 3ds the screen is black. I tried deleting the "extdata" file and booting without the DS, but no luck. Now no matter what I do my 3DS seems bricked. Is there anything I can do to fix it? I've heard of hardmodding, but I don't know if it's capable of fixing this. Thanks.

Edit: I also have backups of both of my NANDs before I started this on my PC.
