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!

Fuck nds-card. They have their little spies all over this place.

Itll be f***ing hilarious when they try to inflate the DSTWO price when its supported.

 

[annson24]

The problem with the DSTT and why the thread is flooded with it is that the chipsets vary so much, so what works for some of us doesn't work for others. I have 2 that just won't work, and it's due to the chipset.

Have you searched for your flashchip's datasheet? It will not be supported unless the datasheet is provided to the dev.

DSTT for now it does not have good support


does not work


Acekard 2i is the best working 100%.

keep working hard
thanks for what exists

It do have great support already, the question is what flashchip do you have with your dstt?

Other than them raising prices (by up to $2 only, correct me if I'm wrong), is there some dirt on them I should know about? I ordered and R4i RTS Gold cart from them for NTRBoot a couple days ago, so reading your post, makes me too curious about them now.

They won't. Nobody will buy a DSTwo for ntrboot if they can buy an R4i or Acekard for cheaper. The only people using the DSTwo functionality when it is released will be people that own one already.

They're fine. Granted I only ordered one card about a year and a half ago, but I didn't have any issues at all. Took about a month to get the card I ordered but I did use the cheapest shipping option.

I'm a bit lost here because of all the R4i naming confusion. Some help would be appreciated.

I have a n3dsxl on 11.4 and I have the R4i Gold 3ds Deluxe edition cards (Gateway clone that worked on 4.x mset). I have both the white card 'starter' (which loaded the .3ds files) and the grey card (which is for .NDS files). I've read that the 'starter' cart can be used for ntrboot on v 4.3-4.5 only, so that's out, but can the grey NDS cart be used on a 11.5 system? All it's got written on its sticker in front is R4I GOLD 3DS

Read the readme here: https://github.com/kitling/ntrboot_flasher/blob/master/README.md it has pictures of which ones work.

Thanks, I looked it up and the pic of my cart isn't on it. What I have looks like this - http://www.r4ids.cn/images/R4IGOLD3DS-fan1.jpg
Is this the RTS card (or any other compatible card) with a new sticker?

 

[Timburpton]

Might be a noob question. But is there any, any chance that you can brick with NTRboot? And I'm not talking about bricking because of sudden battery failure or something. I'm talking about bricking under ideal conditions and assuming everything was ok

As far as i know, only you can brick the cardtrige you use it for it. Because in the next steps send you a error message if something go wrong.

How can i check if a DSTT will work?

Use the flasher and see if it says your card is supported

 

[yacepi15]

Use the flasher and see if it says your card is supported

And... If the updater lefts the card on writting: 99%, it wont brick?

You wouldn't be able to pass through the cart selection screen if your cart isn't supported.

You actually have it. The picture you linked is the CTR flashcart, but it came with an NTR one too (the starter). It should look almost exactly the same, except white with golden print. It's the second card from right on the girhub page.
Also if you decide to go with it, could you please post your card dump here? It's the only one missing.

No
You can sort of brick it, but you have the unbricking tools already at hand. You can't brick the flashcart, because Godmode9 can unbrick it provided you have a backup (they can be found under restoring single system)
You can't really brick your console if you follow 3DS.guide, but if your battery drops out or something, NTRboot can still save your device and CTRtransfer using Godmode9. You might loose some device specific info (it's almost like getting banned), but you can still innstall CIAs and play cartrage games.

The white cart is CTR, the grey is the NTR (NDS). I don't know how the guide says the CTR one can be used but it does mention that it only works on fw 4.2-4.5. But I used the grey cart and it worked. I managed to dump and inject without any error and used the method successfully to boot into safeb9sinstaller. I already have a second console with b9s so I went with that method.

Oh, thanks. I don't have it so I didn't know, but I'll submit a bug report . anyway, could you provide the flashcard dump? If you look at 3ds.guide, it's the only one missing.

Yeah, I'll do that when I get back home. I think the guide made a error with the carts. The white one is the one which had the ROMS and could only be used after the NDS profile trigger. The grey one is the NDS cart which can install mset. The white cart cannot read .nds files afaik and will certainly not be recognised on OFW. The grey one worked on 11.4 so I think R4i just supplied a RTS cart when they gave the gateway clone.
I'll upload both the cart dumps once I get back.

 

[easycrashing]

How do you use acekard 2i if it doesn't take higher firmwares?

I do have a b9s new 3ds on 11.2
