prxdecrypter v1.3 with 3.30 support - Image 1Group of homebrew developers Team C+D released the PlayStation Portable (PSP) FW 3.30 decrypter just before April, and it wasn't an April Fools' joke. However, that development is still unable to support homebrew or downgrades as of yet. But still, it was a momentous step.

Anyway, when it comes to decrypting things, it seems that Team C+D are not the only ones capable of handling the job. Jas0nuk, for one, has been providing the homebrew community with the same goodies. And today, he did update his own prxdecrypter to accommodate 3.30 FW support.

"If anyone wants it, here is an updated PRX decrypter which supports 3.30 PRXes, whether they are signchecked or not, GZIPed, and even RLZed. Should be useful for OE modders when 3.30 OE is eventually released," posted the developer himself. So that's an open invitation for every one to try and check this program provided that you know what you're doing, of course.

Unfortunately, even the coder himself is yet to try this application. He mentioned that all he did was add all five sets of 3.30 decryption keys and re-compile the program. Lastly, Jas0nuk also noted that a confirmation that prxdecrypter 1.3 works will be highly appreciated.

Again, we repeat that the coder himself is yet to try this application, so there is a risk involved if you ever decide to try out this decrypter on your PSP.

With that said... any takers?

Okay Make a folder on your memory stick called "enc" and place your encrypted PRXs there. Then run the app and press X to decrypt them.

ALRIGHT? i did that but I dont see anything in psp that is executable!!
p.s You can call me Noob, or w/e the hell you want, I really dont give *****...quiet frankly I didn't spend enough time on this, so i really don't know much...

first rofl second no it will not downgrade your 3.30 psp its a decrypter not donwgrader it decrypts the 3.30 firmware off a 1.5 or custom firmware not on the actual 3.30 firmware

there will never be a downgrader for at least 10 years......

   Re: yoti93 (Unregistered) - 2007-04-18
 » Yes, it can!

But at first, you need to prepare your PSP - hit it with a hammer or crowbar. Then, open it, take the NAND memory, unpack the 1.50 FW, put it there (to write it use a pencil or a pen), and glue your PSP back to it's normal shape (very nice puzzle!). IT WORKS!

Major noob question here. Just came into the psp scene i did.

1) What's a Prx?
2) What does it do?
3) What does the decrypter do?
4) What is the point of this?
5) What FW do you need? (3.30 sony or 3.30 OE?)
6) THANKS!

6) THANKS!

1.a prx is lyk a list of commands, e.g could tell the psp to autostart a umd when its inserted
2.answer above lol
3.pretty simple m8, just decrypts them so u can see how they work?
4. atm no point for you, this is for hackers
5. sadly you need a hacked firmware. e.g 1.5 or the OE ones
6.bleh every1 starts out sumwhere

Can someone please be kind enough to make a quick noob guide on HOW to install the PRXdecrypter 1.3... cause in the readme that came with it, i don't understand much, I tried and it doesnt seem to work...

thank you

   by sashimi (Unregistered) - 2007-04-07
 » yaa

1) prx is a binary module, which can be loaded/unloaded at will by the firmware itself or by a third party program (umd game or homebrew). Windows DLL alike if i may.

2) See above

3) firmware files are signed, meaning they are encrypted with the private key of a PKA algorithm (wikipedia PKA for further information). They can be decrypted using the paired one of the psp public keys which list is hidden somewhere in the firmware itself (IPL/ boot stage maybe, I don't know).

4) yeah, as Jordan says, for hackers, more generally for programmers who want to try using firmware prx functions (that's the way for instance some people managed to find out who to use the GPS device...)

5) 6) Jordan already said the whole thing

even on my first day as a psps newbie, i'd managed to understand a sh1tload more than these guys. All it takes is a little time to read. The info is out there, and it's not hard to find.

These lazy farkers just want everything s***** fed to them.

the psp scene is not the only place you will see the word DECRYPTER - which is why everyone thinks it's funny when people are comparing it to custom firmware.

they're not just newbies, they've all got sub 80 IQs

There should be a test at birth, to determine the stupid from the bright... We should then take a leaf outta hitler's book and gas the farking idiots to save having to read their BS online.

controversial i know, but it'd make the world a happier place ultimately.

1)dark alex would be registered
2)dark alex would not post under an unregistered
3) im pretty sure he would not keep this to himself since hes released 7+ firmwares to the world to improve the view of the psp and more than likely increase the sales of the console.
4) you're an as$.

   by Tasajara (Unregistered) - 2007-04-08
 » .

if by new firmware you mean 3.30 then yes
it decrypts the prxs in the firmware to allow hackers to analyze it and create their own contribution to the psp scene.
unlike the guy above me who writes runon sentences and makes himself look like and as$ trying to be sarcastic.

Master sarcasm and then try to post a comment that doesnt involve noob or leading anyone with a question that their psp might do housework. I, sir, believe you are the NooB.
