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!

All right mine is the same. I'll assume they're good

Open it with HxD (or any other hex editor) and check so it's not full of FF

 

[dodol]

is that ds2+ or ds2 ? or both will work fine ?

All ready did that, it's not full of FF. That's why I wanted to know the size of your backup, second check.

did someone manage to order R4i 3DS RTS from nds-card today? a whole day passed and they haven't replied to my email yet :thinking:

It's been 12 hours since I ordered mine, no email.

Relax, they will eventually, you have to consider it's the weekend and the time zone differences. I have ordered many items from them in the past with zero issues.

 

[Metalik]

Just checked Decrypt9. Yeah, it sees my AK2i as a legit one. NTRBoot_flasher spews garbage though.

12 hours? That's pretty unacceptable. @AnalogMan You should get a refund.

Are you using version 0.1, 0.1.1 or the one found here:

I can't tell if you're being sarcastic or if you just don't know. You don't pay when you order from that site. You place an order, then email them your order number and they reply with the PayPal account to send payment to. The reply email is what I'm still waiting on. This is my first order from them so I don't know how long the reply usually takes.

Run 0.1.1 and retry and retry. It's a bit buggy it seems.

@d0k3 are you going to implement this NTR flashing method in to Godmode9?

 

[Metalik]

So far neither 0.1.1 nor that forked one work.

 

[democracy]

Well then they should've worked on that more before release. People were excited due to infinite Homebrew (since it works on all versions) and unbricks, but what's so exciting about a release of a program that basically does the same thing as the DSIware exploit? We could've just done that while waiting.

...your a fool... seriously...

Ah sorry... I used the fork and it worked on first try.

 

[astrangeone]

Awesome. Will have to try this out today. (I have my acekard 2i).

 

[KeyMerVin]

Try checking if it´s because of the contacts of the Flashcard... I haven´t read the whole topic, but I know there were/are problems with consoles not recognizing AK2I and you had to put a piece of paper or something like that... can´t explain better xD. There are topics here about that

Cheers, and hope you find the way to enjoy the NTRBoot ^^

I've checked my contacts, even used the paper trick. The thing is that Decrypt9 can clearly see that it's AK2i-81, but flash tool can't

I did. I mean it was like 4 hrs ago, no problems so far...

How old is the card? I ordered two ack2i's around 3 months ago, which are both HW 81. I used the latest compiled flasher and it worked on both cards.

I've got it at the end of 2010. So it's not a recent one.
