Hacking 3DS Custom Firmware by Smealum

[The Real Jdbye]

This is a long ways off from CFW...
But it shows that he has edited system files/code (at least in memory) which is the first step to a CFW I suppose. If he actually edited the files on the NAND then that's even better.
I wonder how long until we can downgrade firmware by using modified firmware updates placed on SD or a spoofed SpotPass server?

It looks like a new image, not changed string.
That means he's either decoded the 3DS internal image format, or he's gotten his own picture viewer to run, which is a good step toward a toolchain.

 

[smealum]

Is it possible to firmware spoof so we can play retail games like Pokemon?

have yet to look into it in detail but yeah more than likely.

How exactly can you cheat in pokemon if you need 4.5 just to make the custom firmware to work, and pokemon requires a much higher version, some kind of firmware spoofing that let's you go online even when the 3ds is not at the required version?

see above

cf clarification post http://gbatemp.net/threads/3ds-custom-firmware-by-smealum.356063/page-6#post-4802789

anywho i mentioned the ability to take screenshots; here's an example of a 3D screenshot :

not super useful but should alleviate doubts that we in fact have our own modified firmware code running.

That would be great then since I want to play Pokemon X/Y and stay on 4.5

smealum: any chance you could help out with http://gbatemp.net/threads/3ds-mitm-attack.356189/#post-4805420 via dumping trusted CA stores? if there's a potential SSL masquerade attack that could use X/Y as a vector, wouldn't that be useful (as nintendo would need to patch X/Y, not the firmware)? that is assuming 3DS-mode games arent completely sandboxed and can even be used to escalate an exploit

He may hacked the firmware but I don't think he will be able to run a rom.
You need to run it from a sd card.

An SD card which happens to be in the 3DS. So no problems there.

Don't think so. It need probably to be run from 3ds slot.

 

[tokidoki11]

So what version will this cfw be?
I'm on 5.1 planning to update my 3ds xl, i miss eshop~~~

 

[Arizato]

Don't think so. It need probably to be run from 3ds slot.

Did you just forget about eShop games?

 

[ground]

why? downloaded roms run from the SDcard.

But i think smea isn't interested in running roms...

 

[DragonSky]

Did you just forget about eShop games?

Yeah.
Still it may be the only way with the 3ds writer.
You need to copy everything everytime.

You might as well, this hack and GW ain't going to any higher firmware anyways

 

[Shin Akuma]

i hope smea only is intrested in homebrews etc

 

[migles]

Yeah.

i see you don't have any idea about what is a custom firmware with rom loader, or how does a custom firmware works on a ps3\psp...

 

[mary1517]

Ok, so you can mace screens while using your 3DS, actually... that sounds neat for me. Can it be possible in the future to record gameplays to the SD card? You know that would be a hit since the capture cards are so expensive. But that's just a question, I don't even know if that's possible.

I do have a psp with flash cfw and a PS3 with cfw.
I know how it works. I don't see it working for 3DS roms if it needs writing to a sd card.

I'd love to see people like you come up with a better idea on how to do it

Great, now I have to decide whether to wait for this, blow 80 on a Gateway, or wait for a cheap Gateway clone.

Who knows what'll happen
