Hacking [PoC] Using a Magnet and a DS flashcart to unbrick a 3DS

[MagicKnight]

What the shit. How can a magnet and an old flashcard even do that? I don't understand anything. Please explain.

Because of a "feature" Nintendo introduced in the bootcode of every 2DS/3DS console (until now, at least) which executes a signed (or haxsigned) code from a "special" DSCart and NOT from NAND just after you turn on the device if the lid is closed and you press some keys. This makes possible to have control of the system at the lowest level even before any piece of software from NAND is executed... or if the NAND is bricked.

It was long ago, and was posted in this section. I'll try to find it, if my memory is correct, I commented on that thread so it must be anywhere on my content.

Thanks,i tried to search for it on google and didn't get anything.

I think that's hardly a realiable source.

coming from one of the masters of flash cards? You need to know WHO is posting WHAT. It's a perfectly reliable source if you're not a moron (no offense toward you... I'm just saying...)

 

[ItsMetaKnight]

This is most likely used for setting up the device in the factory or for doing service repairs, so it's not really a flaw.

I think he is refering to Wiggly, not Apache Thunder.

Paperweights with actual value! I finally won't have a useless brick anymore (if we get DSTWO support)

Same here and i have multiple dstwo carts AND A DSONE so im hoping i dont have to buy YET ANOTHER card just to unbrick. Even TWLoader supports Dstwo at this point so it shouldnt be too hard hopefully :3

Oh... I just read the tweet chain (thread?) and looked at Apache's 2 cents...

But the answer still stands as 'no' at this moment.
Later, but not now.

Still incorrect. The question was "Any". The answer is YES; Whichever one is being used in that video is confirmed to work.

Could this unbrick having a N3DS lid closed while on 2.0? I've read that brick is one of the most "devastating" bricks out there, could it be possible?

That is a MCU brick, so most likely it cannot be restored since there is nothing wrong with the NAND in the first place.

Thanks for the info! Good thing I've never bricked a 3DS with that (or bricked at all), still, I wish there was a way to unbrick that, since it's so easy to brick that way if you don't know what you are doing.

Edit: Also, how does 2DS bennefit from this? I don't own one, but from the one my friend has, from what I remember, you have to put it to sleep mannualy with a switch, so... would it be all the same but without using a magnet? or do magnets have some effect on the 2DS?

Afaik B9S should restore MCU bricks since it skips 3DS's checks even before the system validates the services.
Someone correct me if I'm wrong.

I know B9S works with a MCU brick 3DS console, too.

Yay!!! Pandora's Recovery Cart has been created. Can't wait to see if it gets publicly released.

This must be my lucky day because i have a Ak2i (well sometimes dont detect it but still working) i want try this because i have a bricked 3DS since Palantine CFW time...

I would try the paper shim trick to get the card to read better. It did wonders to a second-hand AK2i i picked up that had contact issues.

Sound cool but how my old 3DS its bricked with black screen i cant see if works or not lmao. I have a OLD 3DS XL working one but if i insert the Ak2i dont work take it out and insert it back until work.,, finally works but do that in a black screen 3DS its more hard... (idk if i explain myself) Well i should try that method with my working 3DS until i see than Ak2i works at 100% percent of tries... and then use it in the bricked one.

Woah!, then are there any bricks that we can't solve? (except for the obvious I placed my motherboard in the toaster and then stabbed it lololololol)

 

[ivoyko]

I have mine bricked since years ago. I wait this solve it because its a really old brick.

 

[Pacheko17]

wait, WHAT.

Someone pls explain.

wtf
I don't understand the use of thz magnet.
It seems like one of those random fake videos found on Youtube trying to buzz xqd
