Flasher For PSP

Here's another one where they hacked up their xbox headset/remote...my hack doesn't do anything with the remote at all and is a hell of lot easier to do.

http://www.pspforums.com/forums/view...=116886#116886

lemme get this straight, iball, have you made your own headset which connects to the serial port? if so, you think you could give a hand to TO in creating a serial/parallel/usb to serial cable?

lol, i'd hack mine but am too lazy,
wait, CAN WE GETG BACK ON TOPIC PLEASE GUYS

So we don't need the remote then? Damn, I was thinking just maybe we could look at the signals the remote sends when the headset is plugged in, to see if there was any difference.

EDIT: T.O. should step up to the challenge and make himself one. It really wasn't very hard.

**** no, this is more of a BASIC (really, really BASIC) audio modification.
It has absolutely NOTHING to do with the serial port functions itself.
It was basic logic on my part.

well, maybe that would help, cos we know its 100% correct....

Notice how this guy basically copies EXACTLY what I already did?
Yet no need to hunt down a PSOne A/V cable for my mod...

Right, thanks for clearing that up for me. So does anyone know anyone who could make this cable? Or find somewhere that will make it, or sells it, or whatever? How was that one done in that picture a while back? I don't see how anything can kick off without a cable. Fair enough you need the theory behind it to actually use the cable in the first place, but without the cable, everything becomes speculation (yes I know this is the speculation forum)

Ok cool. Now, does it plug "directly" into the serial port, or is there some sort of chip that the headset goes through first (like the remote has a chip)?

---

The serial port is not the round 3.5mm jack. It's the flat slot next to it.

I still root for the soldering directly to the NAND, atleast at the start...
Maybe more information will be found this way ?

People seem to want me to do a lot: help write the software, test the software, and build a cable, while you all just sit here and argue.

Exactly. Only audio is sent through the 3.5mm jack.
Serial port wikipedia.
That tells you the PC side of things on what a PC serial port is...

kl mod iBall!

i cnt be bothered to do it tho lol.

I have no clue what this thread has become. And I dont know who could make this cable.

lol ur right,, lets all just get back on topic.

TO doesn't deal with hardware much anyway. You may think it's easy, but others it isn't. Besides, perhaps he isn't interested in building one, he'd rather deal with software, but just needs a means of testing it?

And like he said, he can't do EVERYTHING. Tis similar to people who used to want Fanjita to do everything

Yeah, I know. But doesn't the microphone portion of the headset sommunicate through the serial port? I guess that was what I was trying to say.

Good info on PSP serial port pinouts here...

EDIT: Better displayed in detail here.

:google: is your friend, folks...

yh, hence u hav to use the remote.

Well, if all he wants to do is test it, then he can find people with the cable to do it for him. If he wants to test it himself, then he can try and make the cable.

Ha, yeah I think that thread over on PS2DEV has been posted in here a couple of times now...

yea, to test it he would have to make the cable...

Well, I have a cable at my house. But that's only 750 miles away.

It'd be easier for him to have the cable instead of sending the software to people with cable, since he'd be able to make modifications, etc. Afterall, he's the one with the knowledge on the software side of things, so don't have a go at him for not making a cable.

yea. ^^ Exactly

r u english cool?

this is turning off-topic...

Well, he isn't the only one. This is VERY similiar to configuring Cisco routers through the console port and connecting to sattelite recievers through a serial connection (both of which I have done many times). Besides, I don't think we have a need for the cables just yet. We don't even know what the protcol is, so how are we going to kow what to try send?

It says I'm from England, and I have said I'm English many times. Either way, what does it matter? Me being English is going to help flash a PSP.

And for the other person, okay, I forgot about needing to know the protocols, and didn't realise about your expertise.

im english too =(

so wat do people think with the serial flashing thing? anyone know jedi's progress?

Im working with the open source logger so it will be helpful to test often in diff. scenarios and I have 2.71 which we need.

hmmm, tmk would 2.70 be better?

NOOO, everyones main aim is to crack a 2.71 because if theres an exploit ect ect in there then all others will have that same exploit. I think

:D I wish I had expertise. I just have a lot of experience. I just really don't know how to go about doing this. We are pretty sure we know what the connection speeds should be(4800bps) and what the framing type is, but that still doesn't solve everything. If anyone that has the SOCOM headset running through their remotes has an oscilloscope. Just apply it to the contact points on the remote (you'll need to open it up first :P). Maybe it sends a different signal than what the remote normally sends. If there is a certain increase, we can try increasing that signal again, or decreasing it from the original signal the remote had.

EDIT: It doesn't matter what firmware we use. What it comes down to is the hardware. And who knows, the method of connection may differ slightly between motherboards. However, I doubt this because then Sony would need to open up the PSP to find out the motherboard type.

Fla3h, thats not right, cos if that were tru then any exploit in 2.5/6 would be in 2.01 etc... we wanna find an exploit in something that was in both 2.70 and .71

4800 BITS per second?! Geez that will seem mind-numbingly slow when trying to flash around 12MB (more if for some reason you wanna flash the latest firmware)

Not to put anyone down, but if all this does work, the only person who will be able to do this is the person with the cable. So unless people buy it, this will be useless.

no cos it aint that hard to make one
