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!

Funny, since the fuckers who keep complaining that people talk about the fuck they please are the ones who keep bumping the thread, and considering nobody else is crying but you people.

Our single bump instead of all of the other kiddies with their 5 and 6 messages per page bitching about the fact that they need to have some patience. Don't be so salty, kek.

Why are you adding to the noise then?

 

[Bgreymane]

Ok people, how about we just stop with all the raging?
I'm constantly checking up on this forum waiting for news, only to end up dissapointed when it's just off-topic stuff.
Can we just not post stuff here, unrelated to actual news about this thread?
It's a popular one, and the one who posted it is gonna update us on news for sure, so let's not talk about locking it, because I don't need nor want to search through 30 small posts with one answer about this same topic each day.

Now that is an update we all waited for!
Card prices probably going up ... [emoji16]

It's decrypt9.firm

In Decrypt9 is only NTRCARDHAX not NTRBOOTHAX. Cardhax and Boothax are two different exploits. NTRCARDHAX is only possible with firmware up to 10.6.xx.xx

You can fix that now? Just need another 3ds

Or a hardmod....and it's well documented that having a hardmod makes you 1000% more attractive to your preferred prospective romantic partners, a totally 99.9% verified fact

Thanks, been training trying to progress to a system hfc engineer. My life has been nothing but 12hrs of work followed by 6 hours of studying more cisco stuff.

I've been out of the loop but still kept up to date testing new things ;-)

Could you link to a tutorial? My brother has a Luma 3DS.

 

[KuroGentei]

NTRBOOTHAX has not yet been released! There is also no tutorial on https://3ds.guide It is only a placeholder

 

[Onepunchbruh]

When will this thing release? I want to downgrade my New 3ds XL which is on 11.4.

 

[KuroGentei]

Expected at "end of life." Nintendo has announced that the 2DS / 3DS will be supported by 2018.

Hardmod is the only secure method.

NTRBootHax will certainly be a boot.nds inject (similar to dsiwarehax). Without Powesafe or Firmwareinstaller for Flashcards (Acekard ...) , is this not possible.

There is only one thing wrong about your assumption-NTRBootHax *cannot* be patched. Ever. The things that get saved until EoL are patchable things like Arm11 and Arm9 exploits, so that the 3DS doesnt end up unhackable on the last firmware.
