Hacking Can 3DS downgrade to firmware 10.1 max?

[RaMon90]

Its weird to see many users online only when this kind of topic appears.

Back to topic, I just saw smealums reply. I believe him, if this is true then ok it would be great.

 

[JustPingo]

Well as long as everything get clarified we sure will stop bothering. But for now everything is suspicious.

Sorry to make off topic question but..can a old3DS xl 9.6 be downgraded?

all versions that 2.5 supports should be, but as @JustPingo said, everything needs to be clarified (the way 2.5 gets more ram and access to .code and romfs too)

Sorry just late to the party, and haven't read anything beside OP.

When it said it could work with everyfirmware supported by Hax 2.5, does it mean even the 10.3? Cubic Ninja can be used to install hax 2.5 on any 3DS/2DS right (I was busy last few days so didn't have much info regarding 10.3 firmware)?

 

[Clydefrosch]

if it gets me better emulation on o3ds, i'm all for it.

Yes.

No comment on how possible it is because I don't have programming knowledge to judge, just off topic: Price of Cubic Ninja would be doubled by then on top of current crazy price!

Yeah, there is a huge gap from looking suspicious to thanking smea for his "hidden kernel"

this is not really kernel, this is arm11 userland

 

[insidexdeath]

and since when ARM11 userland allows people to downgrade?

 

[tivu100]

this is not really kernel, this is arm11 userland

So arm11 userland allows downgrading firmware (which involved NAND-flashing)?

 

[Mrrraou]

well svc-mode code can access pxi:am9 and downgrade/install CIAs

Please read what I've said so far.

To try to sum it up (probably wrong, @Mrrraou or @JustPingo can probably correct me)

Apparently there's svc code access in 2.5. Not necessarily "lol full kernel on 10.4 cia install" With this...
Apparently this allows people to downgrade their firmware to one that DOES have kernel (9.2) but not use kernel above it (at least yet).
Apparently this also allows LEGIT CIA installation - that is, the CIAs from the older 3DS XLs with preinstalled games. This has access to installing services but not signature patching, which could mean it can install CIA but not boot them unless they're auto signed/presigned/however this stuff works.
Apparently it works on any fw with 2.5 access, as in not just 9.9 (if you stayed here for safety) but also 10.1 (if you stayed for coldboot themehax) and 10.3 (if you updated for badges/eShop).

Also I'm likely wrong. But I dunno.

But here's the problem, without kernel access you will not be able to flash a lower firmware than your actual firmware to the NAND. Even one of the KARL dev team members I believe mentioned the same thing.

We're not flashing anything.

That's right, I think it to sums up everything important

Not mocking or trying anything funny, just noob wants to learn somethingnew. What is difference between Kernel and this arm11 userland exploit. I often heard people said you need to have kernel access for CIA installation.

You only have to access am:net or am:u for legit CIA installation.

Yea...not happening.
