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!

Pretty much finished setting up a pack that will install b9s and copy essential starter homebrew including Themely, FBI, freeShop, and NTRBootSelector.
All essential homebrew is .3dsx version for both speed and ease of installation
Simple scripts allow quick copying from SD to ramdrive, then back from ramdrive to target SD
Pack is simply placed on the microSD of the flashcard
All you would need is the flashcard with it's microSD, a microSD to SD adapter, magnet and screwdriver bit. With those for items and the pack you can install b9s on any system in 5 minutes or less.
Still putting the process and scripts through testing, but I'll probably make a separate thread later with the pack and a the instructions of how to use it.
I also need to remove things like the titlekey url from freeshop before releasing. My personal pack includes it for my friends, but can't post that online for obvious reasons.

It's taken a little trial and error, writing and modifying scripts, and streamlining the process as much as I can.
Release will probably be put out by the end of the week, including a video showing just how quick it can be done.
Currently requires 37.4MB free space on the microSD and target SD.

Edit: I of course always recommend to just follow the guide if you have a PC. This pack is more as a just-in-case. Better to be hacked but out of date than not hacked at all.

Doing the work of God mate.

Can the R4i (www.r4igold.cn) work? My friend has one of these.

Atm just the R4i gold 3DS RTS work , nobody know if the clone of these will be added just read...

This is the card if that helps. It's the R4i v1.4. Don't know if it's official or a clone. If you know whether it runs wood or Ysmenu please let me know.

I was hoping for something like this lol, thanks!
I also added it to the OP if that's okay

 

[YoloSwagDux]

Will support for R4i SDHC be added?

[yardie]

Can support for standard Acekard 2 be added?

Yeah let me handle it
Ok it's added. Test it now

 

[Acide0]

Hi, someone sale some compatible linker with this hack and ship it from usa or canada ?
I have try 2 times to communicate with nds-card and no answer from them, pass an order 2 day sa Go and no e-mail from them. I only wish that they will not charge my visa card !

 

[bladerx]

Yeah let me handle it
Ok it's added. Test it now

For real?

 

[GerbilSoft]

If it was a MCU brick then why does booting gm9 from ntrboot work on such a system at all?

If GM9 doesn't try to initialize something that requires use of the MCU, then it'd work. (For example, power management.)

Hey guys just wanted to ask,I have a R4i Gold 3ds RTS,but the only thing different is the sticker in front has a wifi logo on it, will it still work ?

A Big thanks in advance !

 

[Snooli]

Hey guys just wanted to ask,I have a R4i Golf 3ds RTS,but the only thing different is the sticker in front has a wifi logo on it, will it still work ?

A Big thanks in advance !

Sorry to dissapoint you, but that's not an R4i Gold 3DS RTS. You can stil try to flash it, it might be a clone...

Yeah that's fine. Just to note my pack is mostly for setting up PC-less b9s installation. I set it up so I can meet friends and set them up with it without having to bring my laptop. I'll probably be finalizing the pack tonight and will probably release tomorrow some time after work

Oops my bad for the misspelling of golf,I meant gold

Here is the actual picture,could it be a counterfeit ?

If you have a modded 3ds why dont you try it?

 

[Cuphat]

That's not an R4i Gold, it's an R4i-SDHC. The carts that are compatible are mostly from r4ids.cn.

 

[sirben]

Oh I see,thanks Squall !

 

[datrico89]

hello everybody what about an (r4i-gold.eu)? I think it is a clone.

 

[PolskiWisnia]

Hi,
is R4i SDHC Dual Core compatibility possible and if yes when we should expect it?
