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!

To anyone who can test this: can TWLoader use the cart while flashed with NTRboot?

If you're using an Acekard 2i, it should continue to work fine, since it will also still function from the 3DS Home Menu. No clue about the r4i.

 

[Xe-rom]

has anyone here reported on the R4i 3DS RTS (the one from r4i-sdhc with the green 3DS mark).
Mine's genuine but it's detected as unsupported.
(Sorry if it seems like a stupid post)

Edit: nvm, it seems like it's been answered

 

[taz26]

Hello, I don't own a 3ds or 2ds but only a nds lite with the acekard 2i and a r4i save dongle.
Is it possible to inject the NTRBOOT with the r4i save dongle? Or will I need the Datel one?

 

[BADDINOROX99]

just out of curiosity can a gateway blue card be used for this?

 

[subcon959]

The OP is pretty clear on which cards are supported. I don't get why half the posts in this thread are asking about cart compatibility when all the info is there.

 

[TheCyberQuake]

Does OP say it's supported? Seriously you can't take 2 seconds to even read OP to find your answer (which is no by the way)
Edit: it isn't supported yet, and isn't even a planned card. So for now no. Maybe in the future, but not currently

Sorry about this guys, but this is very similar. You reckon this will work?

No

...to those Crocs (I had to).

 

[TheCyberQuake]

I was testing it earlier on my ak2i and didn't work. Tried with the latest version and works fine now. Just for fun I'm going to Uninstall hacks from my little bros 3ds (hasn't touched it in over a year) update to 11.5 then install b9s.

 

[rockbmi]

No

Sorted, thanks.

 

[Dave_Chad]

I'd be willing to sacrifice an r4 dual core 2016 if anyone wants to test if they can get it working on that.

I took a gamble on one of my old systems (uninstalled a9lh and updated to official 11.5) to test the card. Luckly, it worked 1st try.

 

[Snooli]

Since most flash cards are clones anyway, could someone compile a list of supported cards not on the list? (clones of supported ones)

Also, anyone with the R4 3DS RTS whatever that's working, does TWLoader work with it? I'm torn between the R4 and AK2i as I have a lot of NDS games I still want to play. The R4 is compatible with 11.5 vanilla, but there are reorts of AK2i working with TWL despite having NTRboot on it. If, however, the R4 is capable of the same, I'd rather buy that.

Would this work for a Flash Cart made for a DS Original on the 3DS

Would this work for a Flash Cart made for a DS Original on the 3DS

Can you read!!!!

 

[xXxSwagnemitexXx]

Can you read!!!!

Oh yeah, I just skipped through it all because I had read about the magnet somewhere else and it didn't mention the specific carts, so I was wondering if it would work with any carts.

--------------------- MERGED ---------------------------

Another question, if your DS hasn't been bricked, when do you hold down the buttons

 

[Disco]

So, it's out Does it support N2DS XL?
