2.7+ Decrypted Dump Exploit Discuss

I'm not gonna put a link up but Madmatty has Admited that he was just pulling us along the whole time.

WAKE UP People!
Fanjita Has Even Stated That He Contemplaits LEAVING US, all because of Fame Hungry Newbs, or Faker Newbs, or just Newbs In general that fake us and get their enjoyment from it. I know this Post is Off topice, but It has to be said, If You Don't Know anything, or if you seriously are just here to pull one over on us, I suggest you leave. No one cares if YOU have 1.5/1.0. No one Cares if YOU hate/Love homebrew. We're here to help the community, The PSP Nation. What we do Affects the World, and their enjoyment on the PSP. So I beg of you, if your here just to start something just for kicks and Giggles, find somewhere else to do it. If you are serious, Read up on what you want to help with, be it C/++ Dev, LUA, ect... Read On it, Get the Tools, Practice! and when your're ready Come to us and Help us, we need all the hands we can get.

As PSP Developers, we are not in it for Fame/Glory...
We're in it for the next person and Their enjoyment.

If our work, our Commitment, and our effort makes just ONE person enjoy their PSP a tiny bit more, then we've done our job.

I think I'll end with that... Back On topic

LOL, why do people post lies? Just to have hundreds of n00bs post in their topic? Well, one day there will be an exploit, found by someone who actually knows what they are doing.

Yes, it's fake. He claimed that the serial port was directly connected to the NAND chip... and it's quite obviously not.

OK, besides that, what about the other theories?
Like the recovery program that gets loaded into the PSP's RAM via the serial and then takes care of the (re)flashing?

I mean, IMHO there HAS to be some way of low level flashing possibility.... how would Sony flash PSPs then?

Replacing the damn PSP with another? Replacing the motherboard? Using their huge intellectual brain to radiate their brainpower and flash the PSP with brainwaves?

Way to expensive....

when they reflash, it Probably does have something to do with a Combo of Serial/MS or USB IMO

It doesn't exist, or we would've found it already :)

More likely they just open the system and attach a flashing device to the NAND chip's leads.

That seems Alot more logical. But Lets leave Options open, it is Speculation afterall :P.

Lets leave operations open indeed. If the serial thing is not going to lead anywhere than, there is no reason for me to buy it from you still vb.

Lets get back to the dump though. Thats what this thread is about.

YAY TO is back!I knew you wouldnt leave!! but I did think you would to take a somewhat longer break.

now i can go and help with the searching for an exploit.i will look through these prx's to see what i can find.

EDIT:BTW,is there any specific prx any1 wants me to look at?

I'll put it to rest then.

Crosses fingers for exploit.

whew Glad to have you back TO.

By the way, whatever happened to that exploit that invovled the zlib in the PSP.

Not sure, no one ever found a proof of concept, so I cant check it out.

Just out of curiosity, is anyone still trying to find an exploit with the 2.7+ fw dump? If not, maybe we should start working with other methods of exploiting it (the zLib exploit, maybe a flash exploit, etc).

Sigh, I was hoping this would get somewhere,
but i'm guessing it'll be a few more weeks until
anyone finds something that CAN be exploited,
and then we wait for the actual exploit. +(.

Sorry FreePlay for doubting you, but I think that experimenting witht the cable could pay off.

According to a post at Technetinsiders.net, Sony uses the serial port to reset the device. It even says there is a diagnostic mode and it could potentally enable USB mode. I think it would be interesting to poke around with the serial cable to see what we can find.

TO, still interested? It wouldn't hurt to experiment with the serial port.

I might be, still not sure yet...

Well i've Finally put the 2.71 files on my PSP for use and I must say i'm having fun with flash tetris :D

(For all of those wondering why I hadn't got it earlier is because I've been fixing my aunt's PC and really haven't had enough time to download much :D Did I say download? I meant upgrade and dump...

That would be a spelling correction. Grammar is sentence structure. Normally I don't bother correcting people either, but it's entertaining to see someone correct another's spelling and make their own mistake.

I'll keep my tips on punctuation and capitalization to myself for the time being.

lets compare them

Kos = Grammer / Grammar
vb_master = Life / Live

ooh big difference...completely different words...

That was pJ14 not me.

@vb_master:
You're the one who build/wanted to build the cable for TO, right?

Well, if you have one spare, incase TO doesn't want it anymore, I'd take it :)
I still beliebe there IS something with the serial, until prooven (100%) wrong.

Anyway, back to topic ;)

I think to really find an exploit we should start disassembling the FW files, looking for ASCII texts will get us nowhere....

I am building the cable, yes. TO has first dibs, then jedimasteryoda, then you.

Or I can just build several if I can find a source of MAX3232CPE's in the USA (not samples).

I can check our local stores here.... there are a few, some might have those chips, or least might be able to order them.

Must be "MAX3232CPE" or would a "MAX3232" do as well?

Yeah it doesnt seem to know psp syscalls.

I need a MAX3232CPE, as I need the DIP version. Don't waste time on RadioShack or anything, they won't stock it.

vb, I decided that I will take the cable.

Ok, good. Should be done sometime this week.

Alright, sounds good. Thanks!

I have been reading thread from the begining and I have hope in you guys. I think you will find something.

Thanks for the support. Hope you continue to post and be active!

Yeah I registered because this is so interesting even though I'm a noob in this I learn some things. I just registered! :)

We sure hope something comes up. And welcome to the forums

P.S. Does anyone know where I can find information on the zlib?

Not sure, I am curious as well.

I could google it for you guys.

i think i recall someone saying earlier in this threat that the zlib isnt in the PSP and that it wouldnt work, but i could be wrong.

Yeah I searched it on google and found that it has something to do with lua and libpng dont think has anything to do with an exploit, but I could be totally wrong.

EDIT: It has to do with compiling Luaplayer.

FreePlay said it is in the browser.

TO could I show you the website I got my info on it?
