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!

There's a difference between whining about a release date and complaining because there haven't been any public updates.

Do you know how long it took before anything went public with B9S? It took 6 months.
They aren't releasing anything until they know it works, it's stable, and more flashcarts work with it.

Guys, please. Stop posting more in this thread. There are no more details announced. It's now just shitposting.

SigHax is much less involved. Not to mention we've suddenly been given a PoC video of this in action (remember NTRBootHax was announced about 7 months ago) so I would expect a release in the next month or two.

 

[incidentallyscribble]

How do you know if your flashcard is reflashable?

Exactly. The PoC video shows it's implemented in some form already, and apparently there's a private beta. So it's not unreasonable for us to expect updates.

 

[gamesquest1]

I'm sure they will update if/when they decide they have anything worthy of sharing, no point normatt telling us all what he had for breakfast simply so we have something to talk about

Especially since they've been very silent about it since December and now we've suddenly gotten a PoC video AND two confirmed compatible flashcarts.

It's been almost a month with no updates except it working on the New 2DS XL (and now the private beta which wasn't announced by the developers). That's a pretty long time.

I hope I am wrong again and he is not holding it until 33c3...

Yeah but let's just assume nothing has changed, it's in beta and he is working on trying to support other cards, he is probably hesitant to announce any stuff he is working on as if he says for example "trying to get it working on the r4 gold.cn cards some people will rush to buy them, resellers will bump up prices and he might not actually get it working and then have a bunch of people whinging that he said he was working on supporting that card and he lied blah blah blah, and tbh it's probably a good thing he isn't too involved in the community as many devs end up turning their backs when they are struggling with something and people are expecting livestreams and Twitter updates every few hours

You are acting like they are obligated to give us updates, which they aren't.

Not really, not at all actually. AK2i, which is officially confirmed, is still $20. So no, the prices are not going up due to this.

I really don't understand what you mean. :-D

I just wanted to help! Let's skip this. :-)

So actually this end like other people stated a few pages ago, same thing as the other developer who never sh

Maybe he just hates us all then and wants to toy with everyone's emotions....either way he hasn't released it yet and progress reports don't really mean anything, you could do 20 hours of live streaming and never actually release anything.....personally I prefer not having the carrot dangled constantly in front of me as long as the gold is at the end of the rainbow that's good enough for me

Exactly, i couldn't have said it better.
You know thanks to them that the n2dsxl is already hackable, and it's a month of his release, and is more than enough information for the moment, even for the big N who's watching too.

 

[RedBlueGreen]

I never said they were obligated did I? All I said was that it makes sense for people to be disappointed in a lack of updates and that it's not unreasonable to expect them. This isn't saying we're entitled to them at all, is it?
