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!

Breathes deeply.
You all ready for some hardcore clone talk?

- 3DS Link is a 3ds flash card kit (3ds card + DS card for mset exploit -- like Gateway).
- It is an identical clone of the same team's R4i Gold Deluxe Flashcard kit which is a terrible clone of the Gateway 3ds flashcard kit.
- The team behind R4iGold Deluxe and 3ds Link is none other than the r4ids.cn team -- they make the r4iGold DS card that is compatible with the ntrboot flasher.
- Despite making 3 dreadful Gateway 3ds clone kits (Orange 3ds is the other one), they made a great decision by including their r4iGold DS card with the clone kits. (im not 100% on if the the other 2 have the same good r4igold, but i don't see why they wouldn't)

That is why your "3ds Link" DS card works with ntrboot installer.

Of course it's a clone. Flashcards don't magically get recognized as something else.

Still, it's good for people to share so that people with a clone card (without realizing it's a clone card) know about it.

I was asking how it was recognized to know if it was an acekard or a R4 3DS Gold clone. I looked it up on Google later, anyway. Whatever.

Sooo, two of the methods require another 3ds or a ds, of which I have neither.
Can someone tell me if the powersave option doesn't need another device?

It's now possible to do it with a single 3ds device. Go back a page or two and you'll see my post where I explain it.

 

[Snooli]

I don't want to undermine the work of the original developers, but it's fascinating how much it has evolved since first launch.

 

[pixelmasher]

@Lia You should add R4i Gold 3DS to the list. It's an earlier version of R4i Gold RTS. It works.

Does anyone know how the hardware of these cards; r4i-sdhc.com, differs from the compatible cards? Just curious to see how hard different types of hardware are to implement.

The issues submitted at the github for ntrboot_flasher have such questions

It's now possible to flash NTRBoot with a single stock 3DS
Only the R4 is usable on 11.5 though, Acekard is limited to 4.3 and below

 

[MrJason005]

Nintendo could in theory introduce a new DS flashcart blacklist in 11.6, and force people to use a DS lite instead

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

They could also remove all those DSi games from the eshop to block the system transfer method

 

[Skur3byk]

Dang it, i got rekt by everything, like month ago i ordered sky3ds+ now the ntrboothax is out and it still haven't arrived...
Now i will have to sell it for cheap i guess...

 

[nl255]

i've attempted 3 different ctrtransfers, i'm not as incompetent as you're making me out to be. i wouldn't be doing a ctrtransfer if i had a nand backup, but again, i don't.

Did you try doing the ctrtransfer with Decrypt9 instead of GM9 and if so, did it work?

 

[MrJason005]

Dang it, i got rekt by everything, like month ago i ordered sky3ds+ now the ntrboothax is out and it still haven't arrived...

you can sell it to people who want cubic ninja, not all that useless

If you'd asked us for advice even before NTRBoothax was out we would have told you Sky3DS is a waste of money :-p You could have bought a cheap console, modded it, used it to mod yours, then sold it again. Would have cost you nothing and maybe you make a profit.

 

[Hihomaster]

can any one tell me where exactly do you put the magnet on a regular N3DS? i tried different kind and it never goes to sleep mode..

I guess so... But the problem is that 3ds isn't very popular in Poland, also isn't very cheap... Soo selling it would be difficult...

Place the magnet in the area by the abxy buttons

wow found it thanks !

 

[Quantumcat]

Oh ok yeah that makes it a bit harder. But still, a used 2DS can cost less than a Sky3DS.

 

[Xerneea]

Are the retailers listed on r4ids.cn reliable? I know it's suggested to use nds-card.com but I'd rather not wait a month, and I've found a website that ship's to Italy (from France) and is slightly cheaper called gameniste.com... Although I can't find any info on it. I'd appreciate some advice thanks
Nvm I'm obviously not getting a response.

 

[soulkyo]

Should I wait for the SCDS2 release or just buy a R4i? Living in Brazil so it might take like forever to arrive.

Can you share your sticker as well as the revision code on the back of your PCB? I am compiling all of the backups into a mega
