(this method will be released VERY SOON if we figure out why only certain pkg's install)

(what will be the outcome of this? pirate ps1/ps2/ps mins ATM & if EDAT files can be compiled into pkg format about 60% of the ps store will be ready to pirate)



this is where im stuck and i need some help from the scene (you) i have managed to find a way to install pkg's on 4.10 OFW only using one ps3.Now NO homebrew will work so all we COULD DO if this exploit gets further is pirate stuff from PSN only using one ps3 which is better than nothing for people on 4.10 OFW so i need a bright SPARK to tell me why only certain PKG'S will install any homebrew or anything NOT OFFiCAL (not made by sony) wont install keeps giving me this error (80029564)

the question is this why are only some PKG'S installing and other are not?

can we (the scene) change that ?

are those pkg's im installing signed with keys that are blocked on 4.10 and preventing me from installing them?

can we sign pkg's?

if so how can i change how it was signed and try install it again ?

can the 1.92 SDK sign PKG'S ?

is this a dead end and we will never install any homebrew PKG'S!!! NOPE ITS NEVER A DEAD END NEVER GIVE UP


for all the people saying the scene is dead it will be with that attitude !!! DO LESS CRYiNG and more TRYiNG and we might get somewhere

The official pkgs are signed properly with signature. the old way of signing things would just place in a sense a dummy signature as 3.55 and under do not check the signatures properly or at all. This is more accurately explained on KakaRoTo's blog.

A game on the PS3 is an executable file in a format called a “SELF“file (kind of like .exe on windows), those “self” files are cryptographically signed and encrypted.. For PSN games (games that do not run from a bluray disc), they need to have an additional security layer called “NPDRM”. So a “npdrm self” is basically an executable that is encrypted and signed, then re-encrypetd again with some additional information. On 3.55 and lower, we were able to encrypt and sign our own self files so they would look like original (made by sony) “npdrm self” files, and the PS3 would run them without problem. However, it wasn’t really like an original file.. a real NPDRM self file had some additional information that the PS3 simply ignored, it did not check for that information, so we could put anything in it, and it worked. Since the 3.60 version, the PS3 now also validates this additional information, so it can now differentiate between NPDRM self files created by sony and the ones that we create ourselves for homebrew. That’s the “npdrm hash algorithm” that we have been trying to figure out, because once we can duplicate that information in the proper manner, then the PS3 will again think that those files are authentic and will let us play them. Another important point to explain, I said a few times that the files are “signed”.. this means that there is an “ECDSA signature” in the file which the PS3 can verify. The ECDSA signature is something that allows the PS3 to verify if the file has been modified or not.. it is easy to validate the signature, but impossible to create one without having access to the “private keys” (think of it like a real signature, you can see your dad’s signature and recognize it, but you can’t sign it exactly like him, and you can recognize if your brother tried to forge his signature). So how were we able to sign the self files that were properly authenticated on 3.55? That’s because this “ECDSA signature” is just a very complicated mathematical equation (my head still hurts trying to fully understand it, but I might blog about it in the future and try to explain it in simple terms if people are interested you can learn about it here), and one very important part of this mathematical equation is that you need to use a random number to generate the signature, but Sony had failed and used the same number every time.. by doing that, it was easy to just find the private key (which allows us to forge perfectly the signature) by doing some mathematical equation on it. So to summarize, a “signed file” is a file which is digitally signed with an “ECDSA signature” that cannot be forged, unless you have the “private key” for it, which is impossible to obtain usually, but we were able to obtain it because Sony failed in implementing it properly.

You cant run unsigned packages because it is 'unsigned', thought that would be obvious

Geohotz "whats up dawg" app I believe is signed, download that and try running that. My bet is it won't run.

im looking to install them 1st i no they can RUN because if i data transfer to 4.10 OFW from CFW 3.55 it RUNS

they just wont install on OFW from my laptop

are u using a proxy to try and installing them

yeah
getting ERROR 80029564 on any pkg not made by sony

thought u was , reason why its erroring is what @TizzyT said

there used to a glitch many years ago install pirated psn games (somethink like that)this way but sony blocked that way

Devs who are looking for the keys I think want to sign them for 3.55 where the PS3 does not check the signature. ATM you can't make homebrew for 3.6+ firmwares run because it checks the signature even if you have the keys and make homebrew with it, if it's not signed and packed properly it still wont run on 3.60+.

This a step forward it would be cool if the pkg's would install unsigned or resigned, on ofw
