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 feel extremely stupid for not asking first, but is 3ds-flashcard.com a good site? already ordered an r4i from there.

I got my cart from there Saturday and it only took 3 days. Works great

 

[Dracari]

Solved my AK2i Issue, the casing is comming apart and forwhat the * ever reason, it was making it go DERP.
Any ideas Why installing it or Restoring the Flash defaults it to the OLD AK2i Logo and not the Pippa Funnel Icon?

 

[Asia81]

I also want to know if it's possible to flash a linker to make our own icon on the home menu?
I have Bomberman Land and I would like a Pokémon

EYY -EEE. scale em down a bit and remove the redundant ones, but hmmm .
you might be confusing it with http://www.nds-card.com/ProShow.asp?ProID=149 unless the guide hasnt been updated for new cards, the No that card is not compatible.
but all compatible cards got thier prices jacked Because of ntrboothax, and new cards announced prices seem to change within 48hrs. the AK2i was pretty cheap before this (mostly because while it had no incompatibilities, but required CFW if you wernt on an really old 3DS FW/ DSi 1.4)

Hi people, I tried to restore my R4i RTS 3DS revolution for DS, but it still doesn't work. I first tried with the HW A7, but LUMA couldn't find the restore file. So I tried the HW A5 and then it did, so i restored it. But my 3DS still can't find the card. I can't open it. It's neccesary for me, because I'm trying to ntrboot a new 3DS XL.

That's weird I wonder why it does not restore the icon.


I use "ak2ifw_update_dsi-v1.44_3ds-v4.0" so I get the game icon from
"Deep Labyrinth - Digital Bros"

My R4i Gold RTS cart finally came in the mail after over 30 days, needed for unbricking a console. On that note, has anyone used Lazarus3DS for unbricking? https://github.com/AnalogMan151/Lazarus3DS

If so, what's sighax_hdr.bin? How do I get that and what exactly is ticket_combo.db? Is that just ticket.db renamed?

Yes, someone did successfully just recently, the thread will probably be on the front page, not sure if here or on the homebrew forum.

If it was @remix2k, I PM'ed him after my post and everything went smoothly. Only to find out the console got an 002-0121 ban.

How long does it take for nds-card to accept PayPal payment?

I got the same error message when trying to access eShop. Probably because some of the files used are modified to make this process work. I’m just happy mine boots again and I can play cartridges

Fucking shit man, and my R4i 3DS Gold RTS came in the mail Tuesday. I could've just waited a couple more days for this and not pay the $20 to wait over 30 days. I have the first listed cart.

 

[DEEP_STEEL]

Haaa.... finally ntrboot for R4i-SDHC is out after so long

Still holding out hope for DStwo :/

Seems like there was a lot of rapid progress on this card a few weeks ago, then .... nothing.

 

[einhuman197]

Anyone has a version of the nds ntrboothax flasher for ds lite with latest flashcard core so I can flash my R4i-sdhc.com card? Only have a ds lite to Flash it currently.
