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

Yea but it just needs to check everything is valid after it creates the modified sysnand.bin then any bricks that occur from downgrading will be down to that step alone. No user errors...well... less user errors.

yep basically a real 'noob proof' method. you hear us developers make this a thing!

Not sure the last part of what you're asking. Are you asking how to return from 2.1? It's step 4 of the guide. You should be using Decrypt9 via browser to restore the emu/sys backups you made in step 1.

like, my sysnand is still on 9.2 and i still have menuhax installed. do i just run decrypt9 and restore my emu backup?
i'm just really cautious after all of this bricking :x

 

[JacksonS]

For the ones that bricked, do you still have your original bricked emunand as well as the processed nand? could you folks check the md5/sha?

My processed emuNAND and bricked emuNAND have different hashes. I don't think it'd be any use for me to provide them because they're unique to my console.

Is your current emunand the bricked 2.1? If you just want to back out, you could just run decrypt9 from sysnand and restore your emunand backup.

I'm at a total loss?? I even tried downgrading my 10.3 emuNAND to 9.2 (before I just cloned my sysNAND instead) and it didn't work either??? now i'm really wishing I had a hardmod

I'm on 9.2 and nada. It won't work. I've basically come to the conclusion that for poor saps like you and me, nothing we can do will help. I'm just hanging out in this thread now. All I can think of is deleting the cia, but no hardmod for me.

Yes. Choose EmuNAND Options, then choose Restore EmuNAND. It'll look for emuNAND.bin in the Decrypt9 folder on your SD card.

The sad truth is you're right.

humm ok i got my otp on my old3ds LL(J) j so how to mak a 3dsx for the arm9 thing?

I thought of that too but that's definitely not a good idea probably.
I had my 10.3 emuNAND a few days ago, and then I came across this forum and downgraded it to 2.1 just to see what would happen? It successfully downgraded, but I didn't know it wouldn't load and I'd have to flash it to sysNAND so I just restored my 10.3 emuNAND..............and now I'm kicking myself for doing that. ****

One of mine didn't end up like this, I need a cookie

 

[Chuu]

Just downgraded and dumped my OTP using the v2 tutorial. Already setup arm9loaderhax with CakesForA9LH. System now boots into emuNAND in ~8 seconds. ^^

Spoiler: Success!

seems like you got lucky :L

Yeah I have a 2.1 emunand backup too, but it was never Timyformated so I'm weary of using it.

Is formatting the emuNAND crucial to the process? I unfortunately don't have that 2.1 emuNAND backup anymore. Sucks for me I guess

 

[Svaethier]

do your systems still turn on though? if so well you can just upgrade your system to 10.5 sorry but it's the truth, atleast you will have your system working but without any type of hax.

Possibly. I ain't risking it. I need some solder and wirres.

just userland hax unless a hardmod

WAIT WAIT WAIT, hypothetically, could you flash the "processed" emunand.bin back to emunand to make sure its working fine before flashing to sysnand?

 

[Svaethier]

yea you are right about userland hax. like I said if your systems can turn on then try upgrading through the button combination.

That doesn't work on an N3DS (it's bricked for a reason - being the N3DS never supported that FW)
Basically what this process does is write a O3DS header into the beginning region (0x200) of that emunand image. (so it boots up almost pretending its an O3DS.
