PKG spoof

[teepo]

Here's a hypothetical question for you.

Suppose I could swap a demo's pkg file with a homebrew pkg file...

Would this pkg install on an ofw ps3? if it did install would it work?

If it didn't install would it brick the ps3? what would happen?

[BahumatLord]

How were you planning on installing the pkg? No package manager on official

[teepo]

I have a proxy server setup between my ps3 and psn, this proxy is able to swap requests for demo pkg files with homebrew pkg files without contacting the ps3 server.. I haven't tried it yet, but if i did try would it hurt my ps3?

[BahumatLord]

I doubt it would hurt anything. As long as you have everything signed right it will work, but as far as I know you'll just get an error message when installing the pkg. Couldn't hurt to try

I have tried this, on 4.31 it gives me an error.
I also have gotten a kernel panic which froze the PS3.
If it works for you, please detail your steps.

BTW, is this Teepo from Shenmuedojo??

[teepo]

never heard of shenmuedojo, I'm going to try it right now...

anyway, I'll post the results, i'm hoping it doesn't result in me having to reformat my hdd, I don't want to lose all my precious trophies, heh.

ok, I get these requests in this order.
1. HEAD sorry I can't post links yet, lol
2. GET sorry I can't post links yet, lol
3. HEAD sorry I can't post links yet, lol

I have no idea what the HEAD url's are doing or what they're even for (maybe i'm an hyper-text transfer protocol noob) but if I don't touch those requests the server seemingly returns nothing other than the size of the pkg file in the response header, the GET request returns the actual pkg in the response

the first thing I tried was replacing all 3 with a homebrew pkg, it gives me an error.

the second thing I did was replaced just the GET request while modifying the HEAD requests' headers with the homebrew pkg's filesize instead of the demo's filesize, everything seemingly goes fine, the pkg installs, but for some odd reason, the pkg it installs is still the demo. perhaps they download the demo twice, first with hyper text transport protocol, then with some other protocol which I'm not capturing ??? I dunno, I'm puzzled.

I'm not sure about installing pkg's via the proxy method you're talking about but last I heard(a long time ago) it was blocked, but even if you did manage to get it to install you wouldn't be able to get the homebrew to run because the eboot wouldn't be signed correctly. We can already get anything we want onto an OFW console by the Data Transfer Utility but anything with a modded eboot can't be run, one thing we can do is to modify files in a games update(not touching the eboot) to enable mod's like with GTA 4, another is to run psn content that is not linked to the OFW system but only if it has/needs an edat fix.

hmmm, I think I've read about that method, but it requires a cfw ps3, right?

I guess the only real use of this thing i've been playing with now is bypassing psn firmware checks.

Why use this method if you are on a CFW PS3? You can just use the package intaller.
