With menuhax, the success rate of getting the am:u handle is greater than directly with browserhax.
Try it with the one that Works for you.
You'll probably going to only install the NATIVE_FIRM cia (that what usually errors on the downgrade).

After you run the downgrader, run this program from @zoogie (from homebrew) to check that you have a clean 9.2:

Did the downgrade again and finished and rebooted with no errors.

Used the the downgrade checker from the link and all looks good.

But it found 3 extra titles, is this an issue?

I'm stuck here at step 8, there's two different 32 character strings to choose from. One is big (15 gigs) and has many extdatas, the other is small (100mb) and only has the extdata it wants me to delete. Which one do I delete? I imagine the first one is my emunand, so I delete the second, right?

Also it says to delete my 3ds folder, but I only want to delete the sysnand part of it instead of the whole thing, right?

edit: nevermind, got it figured out

Are there different versions of SafeA9LHInstaller for O3DS and New 3DS? I believed I bricked m O3DS XL following the A9LH Upgrade guide as I used the latest verision of the SafeA9LHInstaller on my O3DS. The guide does not mention anything about Old or New 3DS. If there are in fact different version of Old and New then the guide need to mention that.

The guide does mention that there are specifics for Old and New 3DS and you need to learn to read:

• The release of SafeA9LHInstaller corresponding to your device:
  • New 3DS Compatible Release
  • Old 3DS or 2DS Compatible Release

My O3DS was already on A9LH so I followed the guide for updating it to the latest A9LH. Point me to where in the A9LH update guide that mention SafeA9LHInstaller for Old and new 3DS.

I apologize. I didn't see that you mentioned updating A9LH. I'm the one that needs to learn to read again. That's very strange that the updating guide doesn't mention the different versions but the installing guide does.

No need to apologize as I don't want other users to brick their 3DS like I did. I just wanted to point this out to the OP so that way he will revise the upgrade guide for Old and New versions. Sine my 3DS was already on A9LH, there was really no reason for me to read the install guide again? I have not updated my 3DS in a few months so I did not know there were 2 version of SafeIntsaller.

I'm sorry for your brick. That's very unfortunate to hear about.

Tagging @Plailect so that he can see this.

I sent my 3DS off to get it hardmodded and restored so next time I brick it, I'll be able to recover easily.

Is there a way to keep the target systems NNID that was on it before attempting to downgrade?

I have the Super Mario White Edition New Nintendo 3DS that came with 11.1.0-34U. Is it possible to install CFW?

If you get a hardmod or through DSiware downgrade method with another system with CFW. Otherwise, no.

So how do I know if my console has browser or not? Mine is 11.1.0-34U so since it is -34, it has browser??

Also I haven't seen any 3DS console that doesn't have browser.

Anything above -0 has a browser.

I'm going to hack a buddies o3DS using the DSiWare system transfer way. I've done it before so I know it won't be an issue, but I have a question regarding the NNID. When I did another friends n3ds, I must have gotten some water head Nintendo representative because they kept telling me that I'd have to do another System Transfer to get my NNID back, only until I insisted multiple times and made up some story about how it was a friend of mine who lives far away, etc, did they do the transfer for me. When I do this next o3ds, I'm going to wait a week and just transfer back my NNID. My question pertaining to that is after I do the initial system transfer to attain cfw, I know that niether 3ds will be able to be logged into. Can we use them how we like, and then when I'm going to transfer my NNID back, can we both do NAND backups, wipe and transfer, sign in and then restore the NAND? Will it work like that?

Hopefully I explained that plainly.

Am I crazy or was there a quicker way to do new 3DS consoles before? I think it was a shortened method to get the otp and install al9h, was it removed because it was unstable or something?

It was removed because too many people reported that their consoles bricked with the OTPless method.
