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 expand a bit on what @MrJason005 said, I understand that to people who aren't familiar with software development cycles (and even more specifically; reverse engineering), that it could seem like developers are just messing about or giving false hope to people. This project (as well as the underlining flashcart library) involves quite a bit of poking and proding across numerous SKUs (if you want to call flashcart variations that) that never followed any real standard or was supplied with documentation of any kind, much less low level programming. There will be developments, because this community is awesome, however timely updates will likely not be a thing (although I hope people continue to be pleasently surprised when they come about!)

and there's something I can do to provide help to the people that knows reverse engineering? like dumping aomething from my flashcart or running any diagnostic homebrew apps?

Has anyone tried flashing their DSTT with the newest release of ak2i_ntrcardhax_flasher?

I can confirm that the new version of ak2i_ntrcardhax_flasher works on the DSTT!

I only ever get Flashcard setup failed no matter what i do.. odd!

You use it without other 3ds or nds?

I means you can use it like the first "official" cartriges?

 

[RedBlueGreen]

Is the R4 SDHC working in any capacity? I see it's in the flashcart_core devices.

The Dualcore? if so, that is still under development.

i Just failed my dsiware hax, my target 2dsxl prompted an error before dsiware transfer from sd... I've to wait 7 days or dstwo support so sad

Cant you just restore a nand backup?

I did but the target 2dsxl didn't receive the dsiware tittle so...

Normally if a system transfer encounters an error mid-transfer, just initialize again the transferring and it will resume.

See the troubleshooting section. You can restore a backup to the source console and move the DSiWare to SD, then move the SD card to the target console, and move DSiWare to memory.

I tried but i doesn't appear on target console when I want to move from Dsiware to memory, seems like my transfer messed up somewhere, but my nnid is on the target console

AFAIK, if you'll be waiting for the system transfer cooldown, you'll have to wait for two weeks. First week to transfer nnid back to the hacked 3ds. 2nd week is for the dsiwarehax.

Did you format the target system at any point after the transfer? That would cause it to not work.
If you don't mind spending another $2 (and you definitely didn't format the target), you can try buying it on the target system then try moving it from source to target again. I saw this worked for two different people.

 

[easycrashing]

of the two, which is the better card if you're buying it?

It's sounds like it as the target console is actually saving in a different path than the source one. Should it ? The target console rebooted after the transfer of the titles and showed me an error so I've not head time to put in my source's SD card in

tl:dr: Some early batches of GW blue cards are identical to Ace3ds plus, which is compatible with their firmware update program and can be RE'ed to get ntrboot support.

How can you determine that a Gateway blue card is an Ace3ds one? I have one "supposedly" from the first batches, and i'm intrigued enough to get it down from the wall just to use it for the sole purpose of ntr-booting.
(Being honest, not like there's too much to do with the white cartridge. That one remains on the wall, but this piqued my interest)

 

[Ramses]

I can confirm that the new version of ak2i_ntrcardhax_flasher works on the DSTT!

maybe on yours, not mine since it's still on that list of carts that are unsupported yet.
