Homebrew [Theory] Possible method to downgrade from 11.0 without hardmod/DSiWare

[C0mm4nd_]

I've been thinking about this thing:
3DS takes files for upgrade from internet, right?
If we redirect the search to a custom site (such as tubehax) we can made that 3DS believes that the downgrade files (9.2/10.7) are 11.1.0-34 files
Is this possible?
(Sorry for my English, I'm Italian )

I think the files would be checked by the console before applying the update. It would throw away the improper files. If this was possible, it would have been done very long ago.

 

[TotalInsanity4]

People have already thought of this, the 3DS and Wii U check version numbers and you can't change those without breaking the signature used to verify them

 

[Autz]

No, because it still has the firmware-list problem. If the system detects that you're trying to install a firmware < of 11.x then it will stop the update and you will be on the same place where you started.

 

[C0mm4nd_]

And with Cartridge is the same thing right?

 

[DeoNaught]

I think the only way to do this is with a Hacked 3ds with Disabled sig checks, and probly no on the custom site(server), (if someone could explain this? always wondered why)

I would also like to know how does 3DS updates work

 

[dpad_5678]

No. Emulating the server won't because the 3DS expects data via SSL/HTTPS aka Secure Server. Even if you made your own secure server it wouldn't work because the certificate with be different and / or invalid.

YouTube on 3DS used HTTP so server emulation was possible aka TubeHax.

 

[Joom]

I swear I see this same thread at least once a week.

@dpad_5678, you can make your own update server using NTR and a certain PHP script. It can't be used for downgrading though.

Rip hopes and dreams

what if we could do a FrankinFirm that has 1.10 Firm but every thing else as a 9.2 files

Nope, 3ds has a minimum version check on 11.0, so it won't work

So a new NATIVE_FIRM but old (other) firmware files? Dude that's like having the worst of both worlds. Unhackable 3DS but old system files and applications so you would have an old as shit 9.2 system that's not even CFW'able.

huh, why would you even do that if it were possible? lmao

I got a better one for you! , use a BTTF* time machine and go 10 years in past and go start to work for Nintendo after many years of work you finally know how signature security works! now go back in future and leak all security you know = profit!

(sorry for my intelligence ,I'm human )
Back to the future*

So many people have asked about this and it's not possible. The only ways that downgrading without a hardmod or a second system can be possible in the future is either a primary Dsiware entry point, which might not even be possible, or an arm9 kernel exploit, which would make downgrading pointless.

It may be possible to inject DSiWare saves in the future - hard to say.

An ARM11 kernel exploit for downgrading may also happen. It's at least as likely as an ARM9 exploit!

Would an arm11 kernel exploit for downgrading even be possible? AFAIK the list of minimum versions is stored in arm9, so the only way around that would be by exploiting the arm9 kernel.

ARM11 kernel exploit is how current downgrades to 9.2 work.

I also thought briefly about other ways of exploiting DSiWare - Petit Computer is similar to Smile BASIC and has QR scanning. It seems exploitable from that, but the real hackers would need to get on that.

It used to be possible to downgrade with arm11 kernel exploits, but it's not anymore. In the 11.0 update, Nintendo added a list that's stored in arm9 that prevents files from a lower firmware from being installed, and the only way around the list is by exploiting the arm9 kernel which would make downgrading pointless.
