It's here!

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!

And then you replied to obvious sarcasm impolitely. That sarcasm was also filled with information that clearly displays the viability of the hax.

What legitimate reason do you have for doubting magnethax?

Saracasm is fine, but I do not like being called a dumbass or any other humiliating name.
If you like to be called denigratiing names put it in your profile and many here will oblige you.

 

[failzers]

I expressed an opinion politely. I don't have to leave this this thread or any other thread, if it bothers you or anybody else to read stuff that bothers them to the point that they are willing to denigrate such person, well they you and anybody else can just go jump in the lake if you get my drift you know what you can really do.
It seems that an atmosphere of blind following has developed and god help anybody that goes against this mad flow.
I don't appreciate being called names and if this forum falls to that level then let me tell you right now I can hold my own against the best of them.
And you can take that to the bank.

You don't have a reason TO doubt. They have the credientials and past experience to prove that it is infact, real. No shit you're gonna get shit on for thinking it's fake. Nobody called you dumbass either. I said you'd have to be a dumbass to not believe it. Can't use idioms now i guess.

You are one of the most pisssant followers I have ever seen and let me paraphrase you in your own words, *you have to be a dumbass" to believe everything you read"
Hope you like the taste of shit
That idiom for you enough??
LOL
What a pissant indeed!

Yeah, I just hit it too. I was considering replying back but he'd just dismiss it saying I'm an idiot for believing this is real or something like that.

 

[Deleted member 389726]

Well this thread has just fallen down a deep hole because the OP hasnt posted any updates and now there are flame wars going on here. I know this is temp, but you guys can at least have some decency before intentionally pissing off other users. If it was "arguetemp" I would get that but it's not. So let's try to be respectful to eachother and wait for Normmatt to post something rather than rip eachother apart while waiting.(This is almost as bad as the things I see on the Cemu thread and how people flat out disrespect Exzap.)

 

[The Catboy]

i have my doubts this magnet hax actually exists

I was going to reply something pretty nasty, but I guess i will let others see you for the dumbass that is you

You actually annoyed me enough to crawl out of the shadows I was hidden behind.
First, your original comment was just out of nowhere. You didn't explain why you thought it was fake, you just stated it randomly. What did you think was going to happen? People were going to be like, "Hmm, I think this guy is onto something?" NO! They were going to call you a "dumbass" for doubting this project. Look at what you have in front of you. You have a clear video with no breaks in it. It's very clear what you are seeing in front of you and that there's no switcharoo going on here. Coupled with documentation that was created by extremely trustworthy and knowledgeable devs. These are people who've been around the scene for years now and contributed projects like B9S and even NDS projects like akAIO. They have the history to backup their claims.
You second comment once again failed to explain why you think it's fake. You didn't provide evidence, you didn't state anything new. Instead you made a snarky remark.
Last, what the fuck kind of comment is that? Again, you failed to explain why you think it's fake. You simply went on rant towards another member.

Answer the question everyone has been asking. Why do you think it's fake? What brought you that conclusion?

My, my another pissant and from the "shadows" too.
Crawl back into the shadows and Learn to read first
First of all I did not say it is a fake.
I said I had "doubts"
Look up the definition of doubts.
In retrospect if I had really thought I was shitting on some new Gospel or Testament i would have just kept quiet.
This is a forum where people can express opinions, doubts, facts etc and don't need to be "shitted" on if you disagree with them.
I don't believe my statement was malicious, nor was it intended to; it was just meant to express a doubt
If this forum has fallen to cesspool standard where members will be considered "dumbasses" and "shiton" for expressing a doubt, it is a sad day indeed
The problem is certain members have elevated certain issues here to cult status and I believe that if this was a discussion in person, these same people would lynch those that did not fall in line.

WHY do you have your doubts? Is it a gut feeling? Do you have some intel from inside? Because from your choice of words being "followers" It seems like you have a personal vendetta against the creator of magnethax. If you have no reason for doubting it then I'll just assume that you have a beef with the creator.

Please tell me why you have doubts about this. I would really like to help you understand why we've responded so harshly.

 

[thisisallowed]

He doubts it because he thinks this is the only source of info on the exploit. Look it up, it's public. The implementation isn't, but it will be (I doubt it will happen this month, maybe in august)

 

[zaqqaz00]

Let me clarify to all
I have no beef with the developers or any forum member.
I did not post to troll either, you can check my profile, I hardly post and never troll-like
My term for "followers" for those members posting insulting remarks and name calling
I just don't like to be insulted and I believe that is where this all spiraled out of control.
My doubts on the subject are mine alone and not meant to be insulting or derogatory to anybody especially to the developers I respect highly (even tho I don't know any of them personally) who have already given us many tools without which we would not be enjoying many benefits we have so far.
My doubts are based on feeling alone, hence the term doubt
My doubt is inspite of all that has been done and (successfully too), what is hoped to be achieved by the ntrthax may not come to fruition and therin lies my doubt.

 

[gamesquest1]

But it has already been demonstrated to work on the n2ds, and from what I gather a few select people have access to beta builds, while I can understand people's frustrations building I don't see any reason to doubt it, although maybe you may be concerned that people might change their minds about releasing or take a long time, but the underlying exploit and method is legit and I'm sure that even if those with an already working version do change their mind or take too long, eventually someone else who doesn't care about price booms will just drop an alternative version

So because it's not released at a time that is convenient for you it's fake? There's a PoC video and the devs behind this are very reputable. What people don't get is why you say it's fake when there is a PoC video to show the vulnerability. The devs have already stated why there isn't a release yet, they want to try and support multiple flash cards. How does that instantly call for you to think it's fake?

Also call me a pissant and I'll report you, most people have asked you a question politely only to get some smug remark back. I won't tolerate for that shit. Fair warning.

You have a clear video with no breaks in it. It's very clear what you are seeing in front of you and that there's no switcharoo going on here. Coupled with documentation that was created by extremely trustworthy and knowledgeable devs.

Not to mention you can test the vulnerability yourself. So yeah, it must be fake, right?

Oh, weird. I know the S7s were G930s which confuses me because they skipped SM-G940..
