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!

You could buy an a powersaves and wait till the method is released

Ok, Thanks for your help guys. Time to hide again

Btw im happy daddy snek lord has fallen.

 

[tech3475]

Im curious, any chance of a ds based flasher being released or will it be 3ds only?

can confirm Ace3ds, old R4 and R4i Gold pro do not work. was worth a shot at least

 

[SquidgyBean]

how do I find out if my Acekard 2i HW-44 or HW-81? my one is very old

If you start AKAIO then press START and go to ---> and press "HELP" it should say HW-44, HW-80 or HW-81 in the bottom corner.

Thank you mine says HW-81 so I'm covered

Worked with r4i 3ds

[TheCyberQuake]

Worked with r4i 3ds

Did it both flash correctly and work correctly? I've had cards successfully flash then not work at all.
So everyone be sure to test before you claim a card works.

 

[Snooli]

Could someone with the 1st R4i from r4ids.cn test this? They seem to be all similar inside and the latest 3 are already confirmed.

 

[pandavova]

Nice to know: https://github.com/kitling/ntrboot_flasher/issues/4

TLDR: the r4idsn . com card is like a R4i Gold card

 

[rileysrjay]

I already had my r4i and a magnet handy and it took some digging but I found my powersaves, just waiting for the official release! Great work so far!

Hi, everyone,I would like to say sorry about my english writing, its not my maternal language.

So I got a R4i gold 3ds RTS v6.1 and the adress is r4ids.cn, the flasher(every version) see/dump and flash/restore the card with no problem. The problem is the hack don't launch, I have try it on a new 3ds xl and a old 3ds xl. I have redownloaded all the files to be sure nothing work

when I have the linker flashed and in the 3ds retail or in cfw when I try to start normaly the 3ds is not booting only blue led but when I'm doing the manipulation with the buttons and magnet, system boot but in sleep mod, remove the magnet and I'm in the home menu.

Someone have does isssu ??

Thank for helping me

By the way I'm not a noob on video game system mod/hack, I have hardmod a lot of 3ds since the hack have been release !

 

[c4388354]

Acide0: Have you got a "boot.firm" file on the SD card of the 3DS you are trying to hack?
I believe if 'Boot9Strap' can't find a valid payload then it will just shutdown the 3DS.

I can for sure say that the R4i Ultra also works:

Dumping flash
ChipID: 00000FC2
HW Rev 44444444
Detected: Acekard 2i HW-44

[MrJason005]

Interesting, a lot of "unsupported" cards seem to be supported.
Are any of the unsupported card users able to use them again as normal DS flashcarts for .NDS ROMs?

--------------------- MERGED ---------------------------

I've read that the reason the devs didn't support the DSTWO is because once you flashed it with a .FIRM file, it would be impossible to revert back to the normal state

 

[jerbear64]

I can for sure say that the R4i Ultra also works:




[Note:]
- Don't try the link on the label, it doesn't exist anymore, you get re-directed to ad sites

This is because the R4i Ultra is an Acekard 2i clone by Team Acekard themselves- hence why your Ultra is being shown as an HW-44 Acekard 2i.
