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!

If you don't already have it, buy this one instead http://www.nds-card.com/ProShow.asp?ProID=149

If you had already ordered the card, it would have been shipped right now and you'd have your answer Lol. Instead of speculating, just order it or wait for yours to be supported by checking the github now and then. For reference when I ordered my card from NDS-cards, it arrived in 9 days and I'm on the East Coast of the U.S. Besides, the card (R4i Gold RTS) is less than $20 with free shipping that's hardly breaking the bank considering "working on" is no guarantee of support.

I don't get why some of you are all pissy that a flashcart you bought YEARS ago isn't supported. Seriously, suck it up and buy a new one they are dirt cheap. It's not like you're replacing your $200 console. Jeez. It's funny how when OOT3DHaX first came out no one was worried about spending twice that ($40) just for userland homebrew. You guys are becoming too spoiled with your free exploits. Lol

I never cared about "free exploits" or anything?? That's what i would have ordered, the R4i Gold RTS. i wasn't talking about i want a free exploit either, and i'm not pissed that a flashcart isn't supported. if you read my previous points theres nothing about that. If that was the case i wouldn't even think about buying a Gold RTS. Don't get how that talks about me not being able to pay??????? just wanted to know what was more probable. and did you pick the $25 shipping for nds-card? i'd be fine spending 20 dollars for a new flashcart, but hell no am i spending almost half a hundred dollars on one

I'll take that as a no? That site doesn't take PayPal

No, it does, you have to place the order then they will email you, search up nds-card on this forum

I was being facetious, and I wasn't talking about you specifically but everyone in this thread mad that a card they bought in 2010 wasn't compatible on release. No I used the free shipping option. In the confirmation e-mail they state it only takes 10-14 days for delivery, mine came in 9 that's hardly shocking.

I want to create a list containing flashcards which will never be supported, flashcards which potentially could be supported, and flashcards which are supported.

If you know any flashcards with a ROM (such as the original R4), please PM them to me.

If you know any flashable flashcards, also please send them to me.

I'm under the impression that only DSi flashcards can be flashed? Since they disguise themselves as another game.

SuperCard DSOne i and DSOne i mini are flashable, SuperCard DSOne and DSOne SDHC are not. I think they had a PassMe but I don't recall the name.
DSTT as a clone of DSOne i is flashable

Why are u always trying to use an Incompatible flashcard ???? JUST AK2I and R4i Gold RTS it's very easy

Always?

Because the cheap bastard only wants to spend $10 for free unlimited $10-$40 games.

If a flashcard is not in the list, it is NOT supported!

 

[Deleted User]

I own a GEi and I can confirm it's not working, yet. Dumping flash fail. When I put the supported R4i Gold RTS kernel in my GEi microSD, it boots to the menu but it can't play games. It can run the patch for the R4i Gold RTS (.nds), but fail in card check. So, I think that this card is a clone of R4i Gold RTS. Maybe someone can make a patch to make GEi become R4i Gold RTS, or maybe officially supported by ntrboot because it's a clone of a supported card.

(except for clones of the ones on the list)

 

[Zaphod77]

Flashcards that cannot have their firmware updated to bypass dsi blocking will never be supported. (the cards internal flash firmware that it uses to read the microsd card)

Flashcards that can have their firmware updated may potentially be supported.

Smart flash card makers will look at ntrboothax flasher code and work out how to make a ntrboothax update for their card, as it's a great selling point.

Even smarter ones will sell ntrboot-ready flashcarts with no microsd slot and just a ROM chip with B9S v1.2
Cheap to make, and easy to sell

A platinum age would involve a hack that doesn't require you to buy anything, like soundhax was. Free for everyone, no need to buy an R4.

In the Diamond Age, consoles come with Luma Pre-installed. Lol

 

[subcon959]

For me, 4.5 felt like the golden age. Just like 1.5 devhook for PSP.

 

[Zaphod77]

even even smarter ones will have a slide switch on their card.

I know i shouldnt be asking, but i want to be 100% sure about if this flashcart works or not. Would appreciate a response
