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!

I think the guy than its working in this... should appear and tell us how progress go. I dont want be rude but this remember me a little about that Hykem... dissapearing after he says he have a WiiU exploit... i know that was a extreme case... but this really go slow...

While I fully agree with you, I don't find it very likely to happen this time. @Normmatt is non-stop on IRC, usually disscussing Switch. And @SciresM has done a lot already, so I don't think he is one of those people to just show something and then dissappear.

 

[ivoyko]

Well im only a half noob random user and i am a little worried... that is all. A lot of years with a bricked cosmos black 3DS than i cant open for hardmod because screws are really fucked. I never opened it i never touched them but they are fucked... wtf?

 

[SoslanVanWieren]

call it test tax because Nintendo uses their keys with this to unbrick 3ds and test them

 

[failzers]

How bout we call it shut the fuck up and stick to the topic hax?

 

[Keylogger]

Wow really impressive!
How did you find this out?

 

[Deleted member 389726]

MY GOD GUYS. This topic has derailed so much that it practically turned into a f***ing shitpost naming contest. It's name will be decided by the creators and that is that. Simply anything else you call it would be considered wrong. NOW CAN WE PLEASE STAY ON TOPIC AND STOP SPAMMING ABOUT NAMES THAT WILL NEVER HAPPEN!

I still think we should see updates. It's been two weeks since this was announced and there's hardly been any information. I understand developing this will take a while but with no information the project seems dead, and people might start bugging Normmatt and SciresM for release dates. Just seeing a "still working on flashcart compatibility" would be nice.

I think that is the meaning of Soon[emoji769]

Just be patient, time will tell (not even trying to be offensive).

 

[Shad0w136]

I really don't care about the name, they can call it Godzilla hax if they want, I just want to be release as soon as posible.

I can't wait for the release either xD (Well, I can, but I'm trying to be patient), I don't care what its called

I just realised "Snorlax" sounds like some sort of combination sleeping pill/laxative medicine

Wow, now that you mention it, it kinda does o.o I'm amazed people are still arguing what it should be called though haha, but SnorHax does sound pretty cool tbh

 

[pixelmasher]

Normatt's pretty good about stuff, except for when it comes to GBA translation projects.

 

[democracy]

I recommend "Pandora cart" (lol)

We're not questioning his credibility. It's just not seeing any updates at all makes it seem like a dead project. Mostly because of how big of a project this is.

 

[failzers]

Any updates on this?

 

[keyra]

53 pages for nothing? really guys

 

[Deleted member 350372]

And the epic wait begins! Or has already begun a while back! Kinda like Hedgeberg and waiting for him to dump the arm9 bootrom. The answer is simple, time. Just wait it out and it will be released/more flashcards compatible. Bugging SciresM or Normatt will probably make them work slower purposely as a response. And we don't want that, right?
