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!

No name is perfect. Magnethax and sleephax are both easy to say and understand, however sleephax is more accurate (2DS don't use a magnet) so it should win in my opinion.

Ya i agree, those are the best choices. Sleephax more so then magnethax (magnehax).

 

[limpbiz411]

Magnasleep Hax

 

[Joshwraith]

I really don't care about the name, they can call it Godzilla hax if they want, I just want to be release as soon as posible.

Amen my friend. Buuuuut what about calling it sensorhax? Eh? Eh? No? Ok. Well I like ntrboothax at it is.

There are ways to do without a magnet open the 3ds a tiny bit so it's still in sleep mode and stick a thin object into it then press the buttons

 

[linuxares]

Normhax, So easy even normies can hack a 3DS.

That's more difficult than just finding a magnet to use

When I come out of dormancy and see this, I am impressed. We have geniuses here people, listen to them.

Great work zoogie.


I'm currently thinking of the New3DS sleep brick on 2.1.0

lmao sleep mode is FIXING the brick...sort of.


wait, is that an MCU brick? I forget.

I believe it is a mcu brick, or at least that used to be the common knowledge. Maybe we were wrong back then. Someone can correct me if wrong

 

[fig8]

What 'bout
Combohax?(get it? Start+Select+X combo)
Flashax?(flash cart hax idk)
Kernelhax?(Because it flashes a custom kernel to the flashcart)
sleepxploit?

 

[BL4Z3D247]

You say ntrboothax looks clunky, but how is it any worse than other exploits like arm9loaderhax? Also it isn't a sleep sensor, it's a lid sensor. Which gets used for more than just activating sleep mode (some games use it to do something in game)
Maybe I'm just weird and like exploits to sound a bit more technical than just sleephax, and with the 2ds not using a magnet magnethax just doesn't seem right. Which means I'll stick with ntrboothax as the preferred name

But there's no lid on the 2DS.

 

[stl25]

Call it Factorystorehax

 

[stl25]

Since the N2DSXL is also hackable with it maybe it would be fitting to call it GameOverHax

 

[Deleted member 381889]

Please stick to the topic :v

 

[Patxinco]

I really hope @Normmatt doesn't leave us waiting just 'cause of the trash i can see in this thread...
Some people here deserves a good slap for the flood they are making...

Now, on topic, M3i Zero could be one strange option, since it uses a cable for updating his own firmware, so maybe they are not gonna be thinking of it.

 

[pixelmasher]

Just call it Snorlax.

 

[Byokugen]

Or OPHaX, but I like Snorlax(SnorHaX )

 

[Quantumcat]

I just realised "Snorlax" sounds like some sort of combination sleeping pill/laxative medicine

And that is a bad idea! Never take laxatives with sleeping meds, read that on some laxative pills :-P
