Info

@Normmatt has created a way to run B9S .firm files from bootrom via a DSi Flashcard and a magnet! This works on every 3DS on any firmware version.

For installation without a PC, user @TheCyberQuake has created a pack which will automatically install B9S and copy over essential starter homebrew from the flashcard's SD to the 3DS's. This will mainly be used for PC-less B9S installations. If you have a PC with you, use 3ds.guide. Read more here: https://gbatemp.net/threads/481141/

How does this work?

This works because of a flaw in the bootrom. Before the bootrom boots the NAND, it checks to see if Start+Select+X is held down, and if the shell is closed. If these requirements are met, it will boot an NDS cartridge from the bootrom. This give that cartridge bootrom access. You might be wondering how you'd hold down buttons while the shell is closed, and why you need a magnet. If you put a magnet in a specific spot on the 3DS, it will go into sleep mode. Using this, you can boot the NDS cartridge with the buttons held down while in sleep mode! Using a reflashable flashcard, you can boot B9SInstaller using the flashcard, and easily install it on your 3DS.

The 2DS doesn't need a magnet since a switch puts it to sleep instead of a magnet.

What does this mean?

1. Any 3DS model on any firmware can be hacked with minimal effort
2. You can unbrick any 3DS model from any type of brick.
   - Remember, you don't need a NAND backup for this. Just do a CTRTransfer.
   - This does not apply to MCU bricks.
3. Even consoles with fried NAND, or even the NAND chip physically removed, can use this

This is incredibly impressive stuff, and will most likely be released soon! edit: now!

FAQ

Q: Can Nintendo patch this?
A: Nope! Not without a new hardware revision.

Q: My flashcard is blocked by my firmware! Can I still use this?
A: Yes! The flashcard blacklist is not enabled on the bootrom.

Q: Why can't this work with my flashcard?
A: The installation requires you to flash NTRBoot to the flashcard's nand. Most DS flashcards, such as the original R4, have a ROM, which is not flashable.

Q: Can I install NTRBoot on my flashcard without another 3DS system?
A: If you can run NDS roms on your 3DS with it, then yes. If it's blocked on your 3DS version, then you'll need another 3DS system to use it.

Q: Will my 3DS flashcard work?
A: No, only the NDSi flashcards listed above.

Q: Will any other flash cards work?
A: Only the ones listed in the OP. However keep in mind that flashcards such as the DSTT, Supercard DS2 and R4 SDHC Dualcore are planned to be supported in the future.

Q: I tried to do this with my cartridge and it didn't work?
A: It doesn't work with regular DS cards.

Q: Can I unbrick from a ____ brick?
A: Considering the card has access to the bootrom, yes! This can unbrick any brick (except MCU), unless you've taken a knife to the motherboard.

Q: Can I install B9S on the latest firmware with this?
A: Again, since the card has access to the bootrom, you can do this easily! Just plug in your flashcard, boot up using the magnet and button combination, and install.

Q: Does this work on the New Nintendo 2DS XL?
A: Yes!

I'll update the OP if any more news is released

Thanks! That'd be very appreciated Nothing I said was against you, I just hate not seeing any action about this yet.

About 3 months ago I bricked, 2 weeks after the brick... right before I was gonna commit to a hard mod on my n3ds I heard about this. I know things take time... I just really wish I had done the hard mod instead of waiting. It's been so long though that I know that the second I take an iron to my board this will get released.

Hell, maybe I should. It'd be nice for everyone

 

[froggestspirit]

You don't get an answer to that because nobody knows.
Seriously people stop asking "will x flashcart be supported" because nobody knows except a few that don't give info until release.

For what its worth, i wasnt expecting an answer, as I'm just curious, it was more for speculation

I would like to mention that through my own personal test with my carts, really any DSi cart should work. It's only a matter of making it possible to flash the firmware onto the cart to make it work. DSi flashcarts cart should be running a NAND on the cart itself where the ROMs are stored for their headers. These NANDs are both read and write, making it possible for us to access them and modify the NAND (with the proper tool, of course.)
Of course this doesn't mean every single DSi cart will work because hardware and soft. Something like the M3i Zero would be extremely hard to work with compared to the Ak2i. This is due to the M3 Team going out of their way to prevent the user from modifying their cart (doing shit like making the M3i Zero gmp z003.) Where as the Acekard Team had always been rather community friendly and their cart has always been a very easy to cart to work with.

I only say this because this does render it rather hard to guess what carts will work or worth the effort to make work.

Hmm... Would you know if there is a way to determine whether or not a flashcart has a NAND or not? I did read a DSi flashcart comparison list on the GBATemp Wiki with the popular flashcarts such as Acekard 2i and R4i Gold. The comparisons were simple like alternative firmware and updatable bootloader. Hopefully this can be useful for NTRBootHax compatibility.

So in theory every DSi flashcart should be running a NAND and not a ROM chip. Although I can't determine that since I don't have every DSi cart to test.
I do know any DSi cart that could be updated will have a NAND, as that's how that's where they stored the ROMs they used for the the exploits.

The the more I think about it, the more I wonder why NTRBootHAX hasn't been released. If they release it as open source, then it won't be that hard to increase the compatibility.

What do you mean by the cart being updated? Like as in the firmware stored on the microSD, or the actual cart hardware?

Like using an external application such as an NDS file or other method to swap out the header used by the cart.

How about we lock this thread and chalk it up as an epic fail instead, ya?

I recently noticed the section reserved in the Plailect Guide for this exploit has started to collect cobwebs...

Interesting.. But I only see the icon being changed and not the NDS file itself being used.

How about no? Just unfollow the thread and never look at it ever again.

SciresM said he might "accidentally press the upload button" it if nothing comes by september.

You are going to look further into the thread. I am posting all of my research on that thread.

Nice to hear, where did he say that? I can't see anything on his twitter. Could you please provide us the link?

His twitter has his 4chan tripcode, he frequents there all the time. Use a /vg/ archive and search by tripcode. it's the thing that starts with a ! in his bio.

Edit: Here ya go.

For what it's worth, if magnethax hasn't released by September I'll just "leak" it myself. There's delaying, and then there's just being an asshole.

It /should/ be done before then though.

Hopefully this post calms down all people who keeps on complaining about the release, seriously.
