Is cubic ninja the only way still for N3DS, if so why? Why can't we use browserhax? Unless at the time browserhax was patched and OP was never updated?
you can use browserhax.

if you're able to run hb, run decrypt9 and get the fat16 xorpad, go back to your old emunand install your preferred region via sysupdater,
return to hb, inject the secureinfo a of your preferred region. restart, emunand should be on your selected region.

Sorted out already. It was a pain in the ass though.

Soo i heard somewhere that despite having the private secureinfo a, you still cant access to eshop on n3ds. Is that true? I am having a n3dsll white that has never connected to the internet and i think i can trade my private secureinfo a jp for another. Also, is the 3 sd cards method works with n3ds? Thanks 4 your help.

You need a donor system to get online from what i understand. So if swapping from Japan to usa you would want a donor system from the usa. In other words, buy a 2ds. Extract info and inject into n3ds. Than inject some random secure info into 3ds, so it never goes online accidentally.

After i did the swap, i used fbi to delete all japan cia, than took emunand and flashed it to sysnand.

Considering how old this is,

  1. Would it work on an American N3DS on 9.2 now?
  2. Specifically, can I play Tomodachi Life (Eu/JP Legit CIA's) by changing the region?
  • I'm using CFW and GridLauncher.
  • I'm using a N3DS XL on 9.2.0-20U
  • My sysNAND and emuNAND are unlinked.
  • I go between sysNAND and emuNAND through the system settings. (Instead of booting straight to GridLauncher, it boots to a purple menu, which I believe is called CtrBootManager. This then lets me choose either GridLauncher or AuReiNand - AuReiNand boots into emuNAND.)
  • I'm sort of a noob. If this was answered, just tell me and I'll find it myself instead of being lazy.~

1. Region changing still works, there may be an easier way than provided in this guide (in fact there definitely is, look in the tutorials section)
2. Yes, the region changed emunand will work like an emunand of the target region, except you won't be able to access the eshop and it is possible some online activities won't work

So am I right in thinking this doesn't work to change a 2DS to Japanese, since the 2DS was just released in Japan last month?

2Ds was released in japan on jenuary 2016...i'll try it right now and tell if it works

The only issue I have seen is that since 2ds lacks a slider there have been some problems with using old firmware (like 4.5 where setup includes adjusting the slider) on it. But this shouldn't impact changing emunand. And, even if something does happen you can just restore your emunand back to a working version.

It doesn't work on 2DS, i tried now and the emuNAND doesn't start, it freezes on a black screen. I tried it on a New 3DS and worked perfectly, but on a 2DS it didn't.

At what point does it freeze on a black screen and what guide pack did you use? The other thing you could try is upgrading the emunand to 10.6 and then changing the region at that point.

Also did you use a donor secure_A from an o3ds or a n3ds?

Any luck with JAP 2DS?

I successfully region-changed my N3DSLL from JAP to USA a few months back with this guide (the xorpad + hex editor method). Now my JAP 2DS finally arrived at my doorsteps, I tried to change it to USA too so to make local multiplayer work among my other USA 3DS and the region-changed N3DSLL.

I have the 2DS downgraded from 10.3J to 9.2J and created GW emunand successfully. Downloaded all the CIA packs from that iso site from 4.5U to 9.2U, merged together and installed with BBM/sysupdater in GW/CakesFW emunand. However I noticed something odd - the emunand still boots after installing all those CIAs, but I haven't injected the secureinfo_a yet. After injecting secureinfo_a with decrypt9wip, I got a black screen with GW/CakesFW.

Tried different methods each time (GW vs Cakes, BBM vs Sysupdater, removing the 0004001B* etc CIA vs keeping all CIA). Every time the emunand fails to boot with injected secureinfo_a. When I restored the original secureinfo_a, the JAP emunand could boot.

Really puzzled. Any success stories?

The fact that you could downgrade your j 2ds to 9.2 shows that other people should be able to get that region change to work.

Was the secureinfo_a from a new 3ds or an old 3ds? Did you use decrypt9 to do the injection or something else?
