Couldn't modded hardware be harder to patch than software? And isn't that how the process usually goes? Hardmod>semihard>softmod?

That's called a hard mod, and has been done for every console ever, except for the newest ones. Most people dislike the idea of having to physically modify their hardware. And quite often there's some sort of software patch that causes problems with the mod.

The current 3DS hard mod simply allows backup/restore of the sysNand without needing a software exploit. So you can update to sysnand 9.7 and restore back to 9.2 whenever you'd like. No getting around the boot loader yet. But I'm guessing that's because we already have software exploits and people don't care to mess around with hardware stuff.

yeah that last part. There might be a hard mod that could get around the boot loader... Might not be that hard to achieve even but why would anyone bother at this point? I would love a 'permanent' solution but it's just not realistic to expect that to come about at this point. This is all of course me talking out my ass

That's not even a hard mod. It's simply wiring up the data pins of the built-in emmc. You aren't modifying anything.. it's nothing more than a flash card you are writing to.

Yup. I don't see why anyone would bother, when we already can get near identical functionality without modifying the hardware at all.

I'd still consider a hard-mod, even if it's not actually changing anything about the base system. It's still changing the hardware and it's capabilities, provided you actually make it a permanent mod (with a port on the back of the console and everything, not just opening it up to do the dump/restore).

Maybe, but in the console hacking world.. it's nothing like a hard mod.

so many uninformed people post just to post... if you're not even sure of what you're saying then why bother spreading misinformation? 7.x keys have nothing to do with this, nand restores have nothing to do with this, etc etc.

It's amazing how little people understand about digital signatures and asymmetric cryptography :)

I mentioned Nand restores as an example of what's been done, hardware wise. It has nothing to do with the topic, and I didn't imply such (or at least didn't mean to). I'm pretty sure all of my statements were accurate. Perhaps using improper terminology for some things.

So true, I consider myself one of them, so why don't you actually tell people why they are wrong instead of just bitching that they are spreading wrong information, oh wait, I know, to increase your post count. you aren't much better then myself or these people whom you judge so harshly. We are all noobs at some point.

Even the PS3 isn't fully open yet afaik, people still need either systems on 3.55 or soldering skills and the right mods, there is no softmod available for it that runs from the latest firmware. I'm hoping the 3DS scene comes close to the psp scene of old.


I'm not so sure about your info on the ps3. I'm currently running a current CFW that I installed just like any other update. You are correct that you need to start on 3.55 or lower in order to install the cfw. The CFW on my ps3 is written to the nand. There is nothing I need to launch in order to get it to work.

it doesn't piss me off that people are noobs. It pisses me off that, in a forum CHOCK FULL OF INFORMATION and with a search engine like google that can comb through the entire goddamned internet you people can't spend a second to search and get informed before saying "I think that.. but im not sure i'm just making things up LOL!"

It not worth it to risk bricking your sysnand for a shortcut.
Of all possibility, even if we found the key, the no guarantee that Nintendo can't change it through a "stability update".

They can but it'd just be the PS3 all over again.

Anyway, in short: No signing key or bootrom exploit (or anywhere reasonably early in the boot process) means this isn't possible with software.
Not sure about hardware.

As you said, you need to be on 3.55 or lower, so you would need to have been one of the lucky ones who stayed on <3.56 or found a 25xx series or older console for sale on the net to be able to use a softmod, only those few consoles are "fully open". If you have a 25xx series or older, then you can hardware flash your firmware back to <3.56 with some expensive tools or very good micro-soldering skills; but if your console is a newer generation, they never had 3.55 installed on them and can't be reverted to a firmware that far back, so the only other option is an expensive $70+ hard mod.

I kinda feel like we are about in the same boat with the N3DSs. Get one now before it's too late, just like in the day with the ps3s. Actually just looked on ebay around $200 for a ps3.

Why would you want to reinvent the wheel when you can just as easily let the 3DS boot whatever it wants and then subsequently boot a 100% custom firmware and shell? A natively flashable firmware just isn't required.

It's not required but it would be nice :)

I have always been concerned about a used PS3, I assume there is a decent risk the laser or another drive part goes out because it has 10k hours on it and then what do you do?

I have done some reading but can't wrap my brain around it all especial since we only had a ps1.
