Yes! Hear the hallelujah choruses sing! After shortly answering the question of what to do with a 'non-homebrewable' PSP, the Noobz team has discovered an incredible exploit... working on all firmwares up to 3.03!!! The once impossible has been accomplished!



Yep, as a proof of concept, a Hello World application has been released, and boy won't Sony get a nice kick out of it. Here's Fanjita's word on the topic:

"You remember that the only thing holding us back from a downgrader for v3.03 was the lack of a user-mode exploit?

Well, we don't like to be held back from anything, so we went back to basics and looked over some of the old exploits. And what do you know? We found one!

We did a little digging into the old GTA exploit, and discovered that it hadn't been properly patched after all. We'll leave it as an exercise for the interested reader to figure out exactly how we got past the patch (and to give Sony a little while longer before the head-slapping "Doh!" moment :P)"

Here's how to run Hello World:
- You need an original, unpatched GTA:LCS game. See here and here for tips on how to check your version, although it can be confusing. The new copies that you find in the shops now will not work.
- This only works for Liberty City Stories, not Vice City Stories.
- Extract the files from the ZIP into the /PSP/SAVEDATA folder on your memory stick.
- Start the GTA game, and enjoy the feeling of freshly-minted homebrew!

Yes, you will need an unpatched copy of GTA:LCS, but I can tell you right now that it's worth it. On Sony's highest security firmware now comes user-mode homebrew. Congratulations, Noobz team! Way to go!

UPDATE: The Noobz team has confirmed that this exploit has kernel mode access. A downgrader will result from this, on up to 3.03 firmware!
