3.30 FW support for prxdecrypter 1.3

prxdecrypter v1.3 with 3.30 support - Image 1

Group 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...

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!

# stop your killing me — Guest 2007-04-07 10:17

# stop it your killing me with a noob question — Guest 2007-04-07 10:21

no its a decrypter(D E C R Y P T E R) if it was a donwgrader it would say 3.30 downgrader

# o_O — Guest 2007-04-07 10:24

# stop making your self look like a tard — Guest 2007-04-07 10:24

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

# To the guy above m8 :D — Guest 2007-04-07 10:27

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!

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

# NO RISK — Guest 2007-04-07 10:59

LOL. There is no risk, I just don't know if it works. THERE IS NO RISK FROM RUNNING THIS.

# noob guide — Guest 2007-04-07 11:32

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

# ... — Guest 2007-04-07 11:32

Bacause he is not him. look how easy it is to impersonate. He did not even capitalize the last "X". Lulz

# yaa — Guest 2007-04-07 11:33

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

:)

# Does this work on firmware 3.10 — Guest 2007-04-07 12:24

# .. — Guest 2007-04-07 12:53

# NOT FOR NOOBS!!!! — Guest 2007-04-07 13:10

# Meatspin — Guest 2007-04-07 13:34

# yjygf — Guest 2007-04-07 13:52

# O_o — Guest 2007-04-07 15:15

pissed off? but first stands for "f***ing idiotic, really. Second? Third?" No your not even close, so shut the hell up. See I'm not pissed off, that's me on a good day......

# help — Guest 2007-04-07 16:09

how do u make the dycrypter work or how do u set it up im new to the psp

# answer — Guest 2007-04-07 17:11

LOL. if you're new to the psp scene, you would most likely want to STAY AWAY from something like this, as it is mainly for psp hackers to fiddle w/ in their free time.

# Dark-AleX — Guest 2007-04-07 23:46

u guys are a bunch of noobs

my 3.30 oe-a when I finish it it will not got to you people I will just keep it for myself and enjoy it

Dark-AleX

# dvgd — Guest 2007-04-07 23:50

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.

# just palyin! — Guest 2007-04-08 01:37

im almost done with it every1 gets to get it :) im the noob for making s*** jokes

# Meatspin die — Guest 2007-04-08 03:20

That does not work it just closes the browser

# ... — Guest 2007-04-08 03:33

I highly doubt Dark_AleX would call someone a piece of garbage looking at his status anyway.

# Did anyone elese hear this? — uruk912 2007-04-08 06:03

apperantly dark alex bricked his psp doing this true? or just a rumor?

# Lawl? — Guest 2007-04-08 06:24

Its just a Decrypter for the new firmware? am i right?

# No — Guest 2007-04-08 06:44

No it make your psp do all your housework look at the title for this artical noob

# Dark-AleX — Guest 2007-04-08 06:53

joking again what I said was true

u guys are a bunch of noobs

my 3.30 oe-a when I finish it it will not got to you people I will just keep it for myself and enjoy it

Dark-AleX

# Dark_AleX — Guest 2007-04-08 08:43

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$.

# . — Guest 2007-04-08 08:51

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.

# downgrade — Guest 2007-04-08 12:38

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

# 3.30 — Guest 2007-04-08 14:44

is there any way to get FW3.30 to be able to run things like 1.50 or is there a downgrade yet? im new to this stuff and im all sorts of confused

# yayay — Guest 2007-04-08 16:45

i just finished 3.11 downgrader!!!

# woop — Guest 2007-04-08 19:03

I dunno about the whole gassing thing, without all these idiots in the world there'd be no one to make everyone else feel better about themselves.

# Nah... — axelixc 2007-04-08 20:07

this is what I call registered.

he only post comment in maxconsole.

Well, yr sh*t jokes no fun. try something new : )

# hey hey : ) — axelixc 2007-04-08 20:09

i made a 3.11 bricker. u want ?

# Yes — Guest 2007-04-08 21:11

Could you give me the link for that bricker as I need it for my psp

# hmmmm — Guest 2007-04-09 00:15

# !!!!! — Guest 2007-04-09 00:20

ur so rite i must pray to avp2!!!!! GOD I AM Ur GOD

# Wasted Time — Guest 2007-04-09 09:55

I have just read all of the posts and they are absolutly useless! people who are new work out the correct section to ask and there are loads of tutorils to look at, dont spam this area asking for help. all i wanted to know was if the decrypter worked, and after 5mins of my time reading useless junk, all i worked out was that Jas0nuk says that there is no risk. So dont spam this area as people like me want other users oppinon on the DECRYPTER not WEATHER SOMEONE WHO CALLS HIM SELF Dark_AleX IS REAL OR NOT!

# psp — Guest 2007-04-09 12:49

i cant find where the app is on my psp

plz help me do this thing correctly

# Yes, it can! — Guest 2007-04-18 06:49

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!
