Hacking Why is it so hard to create an EmuNand for PS4?

[fate6]

IDK why you think this but you do not need any form of bootloader exploit for an emunand and the switches exploit is not patched on any firmware as it can't be, it is however patched in later revisions of the hardware.

Now as for an emunand it would depend on how the PS4 actually runs and if the access granted by whatever exploit allows the system to be rebooted/load into a redirected NAND.

without samuhax i doubt its possible sadly.

Once again, you need a bootloader exploit to do this. We have no exploits that run before the OS is loaded. It's not a matter of "nobody is interested", it's a matter of "we have no exploit, and no one has found an exploit yet".

You don't need a boot loader exploit for emunand. Patched switches can boot into emunand, there is no cold boot for them.

Running a newer os in emunand would probably require a samu exploit or bypass as I suspect older firmware wouldn't like to find an updated samu. But emunand of the same firmware version should be doable.

News flash: The PS4 is NOT the Switch, you can't compare any progress/exploit on the Switch to the PS4, they do not work the same way. The Switch can "reboot" into an emuNAND/CFW because of various bootrom exploits that can be triggered while still in Horizon.


This is NOT the case with the PS4. The PS4 does not have an exploit that can access bootrom from boot. Once again, you need a bootloader exploit for EmuNAND on the PS4. There are one or two that actually exist, but they're only usable on older firmware and both require hardware modifications in one form or another.

I know they aren't the same captain obvious, but you can load linux on the ps4 & it takes over the ps4.
You could also load a patched version of Orbis.

There would be issues if you tried to run a different version in emunand, which would also affect you if you used a coldboot exploit. I don't think they are insumountable but nobody is bothered to put the amount of effort into the ps4 as was put into the switch.

You do not need bootrom but it doesn't matter since it seems you are not interested in discussion but just trying to feed your ego, enjoy the block list.

Thats's what I throught, if you have kernel access you can access every region of memory and execute anything

Right, the problem is things like SAMU as that is a separate CPU and I don't know if you can just get it to run the latest code without going through an upgrade which would then kill your sysnand. This will be the same with or without a coldboot exploit.

You can probably software emulate SAMU, similar to reF00D on the Vita, but you'd need the latest keys and AFAICT those are hoarded by the groups that have them.

What versions of FW are you talking about? I just bought a PS4 with something like 4.0 on it. Would this be low enough? I haven't done anything with it yet as I'm educating myself currently.

1.76 iirc

Damn, that's freaking ancient. Lol

There are still boot level exploits around, just none have been truly leveraged and none that can be done purely in software yet.

You're talking about cold boot exploits? Like how haxchi works?

Ok so I've only started down the rabbit hole of PS4 softmodding, I'm curious why the guy I bought the PS4 from listed it as 2 different firmwares, like (I'm not sure of the exact numbering) 4.05/5.50 (and some letters).

Kind of.

Yeah maybe it was sold as 4.05 which is upgradable to 5.05, which is more desirable by pirates.

Ahh ok, I understand. So, what would you suggest? Upgrading to 9.00 or stay low and patch the games as I get them? I should probably take this to my own thread, shouldn't I?

Stay on 5.05 for now. Back ports exist and new memes are coming for <9.00

Very well, thank you for the advice. What are "new memes". Is that a typo or some new lingo on unfamiliar with? Lulz

An exploit or crypto was fixed or changed between 7.55 and 9.00. “Memes” are exploits or useful tools ( ͡° ͜ʖ ͡°)
