Firmware 5.03 Says Hello World, TIFF Based Exploit

UPDATE: 04-16-09

Firmware 5.03 TIFF Exploit: Now on Slim and Fat Models. And the PSP-3000?!

Just a few days ago you read about this newly discovered TIFF exploit running on PSP-1000 (Fat) models with firmware 5.03.
Today the same exploit is now functioning on the PSP-2000 (Slim), but sadly, still, MaTiAz mentions no PSP-3000 support…
Or wait… What the… Could it be?!

What you just witnessed appears to be a PSP-3000 running firmware 5.02
that is indeed vulnerable to MaTiAz’s or some derivation of MaTiAz’s TIFF exploit.
As always, stay tuned.

Update: File has been re-uploaded. According to MaTiAz, the wrong h.bin file was uploaded initially. If you had already grabbed the earlier release, simply download this one and replace all files. The “Hello World” message should now display when successfully executed.

The prospect of running homebrew on PSP-3000 units is rapidly inching closer, as homebrew developer MaTiAz has released a TIFF-based exploit in the form of a “Hello World,” proof of concept application.

The exploit is run from the PSP’s photo menu, taking advantage of a vulnerability found in the TIFF image library. Should be quite a familiar process if you were around back in the heyday of the PSP scene, when software-based downgraders were all the rage. Nonetheless, installation instructions can be found in the included readme file. Note that the current version will function only on PSP-1000 units. A separate release is being prepared for Slim models, specifically the PSP-2000 and PSP-3000.

MaTiAZ notes that “a bit of awesomeness” is due out within the coming days, so keep your eyes peeled. After a long wait, the gates to homebrew access on firmware 5.03 have been opened up.

UPDATE:

A Hello World is a program that can show a community that has managed to
accomplish something that has not been done before. This new version is
compatible with the PSP 2000 (PSP Slim & Lite), but is not compatible with
the PSP 3000. This new version is compatible with the PSP 2000 (PSP Slim & Lite),

Wee do not yet know what will lead this flaw. Wee do not yet know what will lead this flaw.

Great. I'm a bit pessimistic about the new psp rumored to be coming later this year, you figure the firmware is being rebuilt from the ground up? The PS3 still hasn't been cracked yet.
