Hacking Is b9s really unbreakable?

[NoNAND]

I mean. Can nintendo remove it via an update. Or lets say your 3ds broke and and you send it in for repairs. Are they able to remove it.

And can you get into legal trouble if nintendo sees that you have b9s if you could send it for repairs.

 

[ManuelKoegler]

Being that it's unpatchable and can be applied on all current 3DS models no matter the firmware through hard mod, yes, it's unbreakable.

Ok. Thanks.

I'd say a hammer'll break right through it before Nintendo does.

There's another thread about this on the front page right now

TL;DR don't send it to repairs: yes they will be able to detect it, no it's unlikely they'll do anything, but it's also unlikely they'll actually repair it, just send it back

I don't understand how you guys seriously think Nintendo can't fix an exploit on a device they have physical access to.
Of course they can fix it. They'll always have at least the same access hackers have, plus an army of engineers with full documented access hackers do NOT have.

they would need to change the whole bootrom on every console in the factory.... so yea... unlikely

What you need to understand is B9S uses a vulnerability in the bootrom to install itself. To fix this Nintendo will have to make a new bootrom. To distribute it they will have to make a new hardware revision. While all of this feasible it is very unlikely that Nintendo will invest the money to do so.

Contrary to popular belief Nintendo is a very small company and they don't have an army of engineer ready to fix whatever vulnerability hackers found. In most cases they don't know about the vulnerabilities and the way to exploit them before hackers found them.
We know now how Nintendo is "fixing" hacked firmware in factory cf NTRBootHax.

So while Nintendo can indeed remove B9S from a console, the vulnerability remains and we will be able to reinstall it.

Yes but what YOU must understand is the original poster asked about REMOVING bs9 when the device is serviced, not, blocking it.

And I was just answering to YOU saying they can FIX it not just REMOVING it.

Anyway the OP does have an answer now.

Only a new hardware revision can break it, and I doubt they will spend $$$ to do it. But yeah they will detect it, and won't repair your device. Breach of user agreement and stufd

Is it possible? Yes. You'd need new hardware as the bootrom is physically inside the SoC.
And for most electronics hardware repair nowadays, it'd be more economical for them to just replace the whole motherboard rather than having the technicians de-solder and re-solder a BGA chip.
As the exploit was only revealed recently, it's not possible for them to have already produced a new motherboard revision and shipped it to repair centers. (And most likely will still be present in the unreleased N2DS XL as well).
Would Nintendo invest in a 3DS board revision at all? Probably, but not in the short term and most likely not at all. Right now, their production hands are tied for the Switch. Later the 3DS may not be profitable enough to justify a new revision at all. (They'd have to order a new chip design from the fab and those have to be in bulks. The remaining sales may not be enough).

4DS will have it fixed though
It will kick you in the nuts if you try to temper with it

B9S is removable just like A9LH, that's why CFWs have to have FIRM protection to prevent that from happening.

sighax is not patchable, however. You will always be able to install it with a hardmod or ntrboothax.

Yup, exactly, the exploit needs a hardware revision to fix.
The changes to the FIRM partitions so it'll load your custom firmware can be overwritten by an update if the CFW doesn't protect them. (e.g. Gateway).

Does luma protect them?

 

[trinhno]

Does luma protect them?

Of course. That's why it's recommended for most people.

Oh ok.

 

[Cuphat]

Does luma protect them?

Yes. The same protection that worked for A9LH also protects B9S/sighax. Luma has had this protection basically from the very start when it was called AuReiNand. ReiNand has it. Cakes and Corbenik also have it, but you could disable (or had to enable) it. Gateway is pretty much the only CFW that manages not to include such a basic thing.

Does anybody know why i cant open the rosalina menu. I have luma 8.0 but it freezes on boot if i press l down + select
