But i guess, if this would be the case, sony'd better make sure no one finds out how the update works, else we could extract this vital information from this update en use this to our advantage!

also, the extra software features (if they come) will be released with update 2.0 (cause it's now a 1.5 wich means it doesn't add extra features, right?)

Well the big question is, how can we dump the existing firmware from the PSP? I bet Sony have patches for security holes that exist in the JAP PSP firmware.
As much as I want to update my PSP I'd rather be a bit skeptical and wait to see if we can dump the existing firmware first so we don't loose anything by updating.

unfortunatly, if such 'holes' would excist only in the JPN psp, wouldn't homebrew be less supported? I mean, if only people with a japanese psp could homebrew, then less people will get involved with helping the scene.

Heh, as soon as we can exploit the buffer overflow that happends with the images there will be homebrew, I belive.

Unfortunatly homebrew at that point would only be for people with JAP PSP's.
But if someone somehow could dump the existing JAP PSP Firmware it would be great because then everyone could run homebrew.

Btw, can you run the new firmware update and not flash? Is everything in english?

What chip is it stored on btw?
I wish I knew someone who would do that =). I simply can't afford equipment to do it and I can't sacrifice my psp :P since it's expensive enough as it is.

Actually, it is now CLEAR that sony changed more than they said with update 1.5...

Particularly the way INFRASTRUCTURE MODE is handled by the PSP.
Before I could use some sort of Wifi hack that allowed me to check for firmware updates from the PSP using an Ad-hoc point as explained here :
(although firwmare update are done in infrastrucute mode, Ad-hoc + Windows ICS acted as infrastrucute mode)

Since i installed 1.5, this doesn't work anymore!!

Alcahest, are you the same Alcahest from Xlink forums?

Shame that the firmware updating now wont work with a USB key, didnt get a chance to try it in the end.

Instructions and details are available on the jp playstation site. Interesting that UMD part, eh?

yes i am MarfPSP.
I've been toying around to see if using a defined SSID and WEP key would help but no, nothing :/
damn upgrade :E

I guess sony did this to stop possible tunneling of connections designed for infrastructure mode, to force users to use Sony's server :/
I hope i'm missing something and i'm wrong though. ;)

Later,

Yes the UMD part there is very interesting.
Could one see demo UMD's that contain the update?
Demo UMD's which maybe will follow in a magazine?

noticed that the old fake firmware upgrade don't work anymore, it say "damaged data"

Orion_ · Joined: 27 Jan 2005 Posts: 69

when Trying to start the 1.5 update again it says that there is no need to update without even starting the updater. I replaced 1.50 string to 1.60 in the file at: 0x64C, after that the updater program launch but say that data is corrupted (file checksum ?)
this mean that we now can't start the only 2 official program from memory stick we had :/

You're running the programs fine. It just refuses to update the flash once its running.

Besides, not all of us have upgraded yet. :)

jabberwock · Joined: 24 Mar 2005 Posts: 6 Location: Netherlands

no, but you will eventually. At least most of us will. We want to play games with this machine, and if that means we have to update....we have to update....smart move from sony!

Could someone who has done investigation on the serial data on the remote try monitoring the psp update process on that port? If I were to write something like the psp updater I'd include some kind of basic debugging output, and since it's already been rumored that the dead-psp treatment involves a dongle being attached to the headphone remote port it might make sense for that the be a debug port, too.

I'll probably be doing this myself, but more experimenters means more opportunity for discovery.

Well, we surely need to dump the existing JAP 1.0 firmware.
When that is done we can check if we can flash back to old flash files.
The 1.5 firmware update can have a protection against flashing older files, or it may just be for the "beta leak" firmware?

Rom chip always has two pins for power supply. There are secured chip that will destroy its content at once when finding the voltage applied is not correct.

That is what I've seen somewhere.

is it known if the remote is serial?

I just opened mine up now so I could get better contacts on the wires, was trying to check for changes in resistance / etc when buttons were pressed, but it was a pretty weak attempt.

I saw this page, I';m not sure how similar MD remotes are to the psp one.

Is there any way to run terminal or something like that and have it display anything that is sent to com1 on the pc?
