POC - Run 5.50 Debug Firmware on PSP-1000

Quote:PSP Ddebug can be use to test and debug the games being developed. This tool is primarily use to flash
all the official firmware without any exception on all PSP. It can also restore the factory state of the firmware.

So if a flaw is found (sooner or later) on newer firmwares wee can use this to downgrade all
PSP's firmware to a less protected state.

PS: The tool is already compatible psp 1000, 2000 and 3000!!!

- Yoshihiro @ PSPGEN

Our old friend Yoshihiro has just created a utility to install debug firmware on a normal PSP
and run without any limitation. A High Level Exploit.

Before talking about this technical feat, a few small reminders and clarifications are necessary so that everyone can well grasp.

Firmware debug, debug console (testing tool), what's all this?

A debug console or console TEST, can test the games in the form of files or media burned during development.
PSP also means that editors have some games to test the preview. Of these copies of console games
"retails" (commercially available) do not (normally) and, similarly, the copies provided by publishers from running on these consoles.

There are "DEBUG" for all the consoles, without exceptions. Thus, PSP, DS, Wii, 360,
Wii and PS3 all have a debug version. In general, they are very expensive and are
distributed at drop-in by manufacturers.

Yoshihiro? But who is that?

For many of you Yoshihiro is a name that does not say much but others knows him.
This well is singular at the origin of a number of impressive things about the PSP and its specialty is the Kernel Hack.

Note the bottle of wine to make "more frenchy"

Who can't forget Change Version (which could change the version number of 1.0 to 2.0 in order
to downgrade its console 1.50, the firmware of all miracles), PSX-P (PS1 emulator)

He is also the first to have demonstrated that a game could be launched from a memory stick and, for the anecdote,
it was even eXx1l3d from some U.S. sites as it was then still regarded as "piracy". How things have changed since then?

He then teamed up with MathieuLH and the name of their team was sonyXteam. Dark_Alex joined the group for some time before going to other places.

Yoshihiro MaGiXien and July 13 2006:
two friends sharing a common passion.

Yoshihiro is a pure dev 'undergroud "more passionate about the hacking as any game has yet to demonstrate that
even" rusty "by a few months of no activity on the PSP scene, it has not lost his hand . For those who wondered
if it is part of GENyUS staff, the answer is "no comment" at this moment.

The 5.50 firmware testing tool in action on a PSP-1000 retail:

As you will see, Yoshihiro has just created a utility to flash the firmware to 5.50 Testing Tool on a PSP-1000
retail and running smoothly with all the additional functions active.

If it is not the first to have successfully run a Debug Firmware on a PSP "retail" (see [POC] A debug firmware on a PSP normal video),
it has, for against, managed to create a universal installer wee talk later.

Here is video proof:

What good thus it do?

The 5.50 firmware testing tool is not distributed because it is not a public release. The upload is not possible.
The installer itself is without any worries and allows flash all existing firmwares (debug or not) on a PSP-1000
(version PSP2000 should one day ...). Practice simple and effective, this tool may be placed online.

Beyond what you could do as individuals, this will enable devs to study its operation and who knows, one day offer the same menu in a Custom Firmware.

Meanwhile, for the record, please be aware that the current PSP Go running with a testing tool firmware 5.50 ...

So Stay tuned ....

Interesting.
I wonder if this is a debug mode built into firmwares, or a completely different firmware build...
Wonder what that 64MB RAM thing for the PSP-1000 does...

Thanks for posting :P

interesting read. though i couldnt understand a little bit of it

i am interested to see what this is capable of :)

honestly, what use is the debug firmware, without a debug unit?

You don't need a debug unit

lembas · 20/06/2009 02:55 AM

but what are you going to do with the debug firmware, on a consumer unit?

you won't be able to run games off DVDs, as you won't have the necessary hardware.

hm.. maybe wee'll have acces to new different options (:
sad that linux on psp is so bad
