Hello all,

Little bit of background on my n3DS:
I'm working on a recently purchased one from a secondhand shop, so the history of it before I got it is unknown. I have no idea if this had already been hacked as it was reformatted when I received it.
The n3DS Version is 11.9.0-42E
I just want to hack my n3DS so I can get a recording program on there to record some gameplay/stream it.

I've followed the 3ds hacks guide to the letter and gotten to part IV of installing boot9strap and the dreaded "A9LH detected! Brick avoided!!" has appeared.
I've followed the link to follow the steps for A9LH to B9S to resolve this but I've hit a wall.

On part II of A9LH-to-B9S guide, I've tried holding down start when powering on but it takes me to the home screen. I've tried holding down select, still the home screen.
In the A9LH-to-B9S guide, it mentioned that I need to remove any .bin files in a 'luma/payloads/' folder but I didn't have these folders when originally doing the frogminer method. I've created them from the root of my SD card like it's shown in the picture but still not working. I've tried removing all the folders and starting again and tried the A9LH-to-B9S before trying the frogminer method but still no joy.

I've seen posts about this could be a false positive and to rename a file to work around it but only if we're sure the n3DS doesn't have A9LH or removing A9LH with a script? (I think this is the uninstalling CFW guide? I've got the godmode9 files and folders from A9LH-to-B9S guide but with it going to the home screen means I can't uninstall it, right?).

Can anyone give me advice about how to find out if I have A9LH on this n3DS? I'm worried I'm going to bricking it

Just tried, it's still going to the home screen
These are usually false positives, but if you're wrong, you'll brick and you'll need to buy and ntrboot card to fix it.

There's a pretty reliable method to check for certain. Go to Frogtool -> BOOT .... and wait about 30 secs.
If it boots a game, you're likely ok to override. If it hangs at a black screen, you are NOT ok.

Whatever you decide, it's your choice you have to accept any possible consequences. There's always risk involved with NAND writing.

Hii im having the same problem, did you found a solution?
Get Luma3DS 7.0.5 from the Github and put the arm9loaderhax.bin on your SD. Hold select on boot and tell us if Luma3DS configuration shows. If no arm9loaderhax.bin is found the system will simply boot normally, so to know for sure if you have A9LH you need to make sure that file is there first.

Sure, it's easy if you have access to a ntrboot flashcart, I think there is homebrew to restore NAND backups from a DSiWare exploit as well (fwtool comes to mind, but I couldn't seem to find a download for it)
Restoring the NAND is not the first thing to try imho. This will revert everything to a previous state: firmware version, tickets, internal saves, Activity Log… depending on how old the backup is, this could be quite some loss.

When using ntrboot I do not see the point of NAND restore anyway – simply install B9S.

While doing some experiments some weeks ago, I tried to backup (not restore) the NAND of an already hacked 3DS with fwtool: It crashed in the middle of the process. (Will continue these tests in the next days.)


My advise on this topic: At the very least create a new image before restoring an old one.

The problem is he can't install B9S.

"a9lh detected, brick avoided" can be overridden if the user is confident that the warning is a false positive.
They should be able to install b9s.
It's all in the guide.
Fair enough, but I certainly wouldn't want to override something saying "brick avoided" if I was a noob. :P
TBH I would probably get a ntrboot flashcart beforehand, just in case.

Have a look at zoogie's post above.
Trying it now. Fingers crossed!

Well, I think it worked. I overrode the warning and installed b9s. The 3ds still turns on! Thanks for all your advice boys and girls!
