TIFF Exploit For 2.71 And 2.80 Firmwares Confirmed!

desoler c'est en anglais mais apparement l'exploit tiff a été confirmer donc un espoir de downgrade

A confirmation, by top PSP homebrew developers, has been sent to us at PSP3D.com, proclaiming that the recent investigations in an exploitation for the PSP, currently possible for firmwares 2.0/2.01, and possibly, in the near future, 2.5, 2.6, 2.70, 2.71, and 2.80 firmwares for PSP has been a success, so far. NOPx86, the one who discovered the initial vulnerability on PC, and the works of Skylark and psp250, who together researched the capabilities of the exploitation on the PSP, alongside the contributions of a dedicated team, including Fanjita (developer of the GTA-based eLoader), have confirmed that there is a lot of possiblility that the TIFF-based exploitation may, in fact, become the next big 'thing' for the PSP homebrew scene, and offer homebrew possibilites for all firmwares 2.0 to 2.80.

Fanjita states: "Alright, time for a brief update with the facts so far.

This exploit is definitely genuine, and usable.

It's unclear exactly which firmwares it will be usable on, but so far 2.0 and 2.01 should definitely work. 2.5 and above are significantly harder to research. 2.7+ will take longer still. The signs are that it may go up as far as 2.8, but that's not proven.

Just to put things into perspective, a combined team has spent at least 60 intensive hours working on researching this so far, and we're at the point of being able to confirm that it will work.

It will take longer still to convert it into something that is actually in a demonstrable form, such as Hello World.

Credit so far goes to NOPx86 for discovering the vulnerability and proof of concept on the PC, and Skylark and psp250 for researching it on the PSP. I've helped a bit too, but those guys have done the bulk of the work."

Though the findings are not at the "Hello world" stage, a landmark which defines that an exploitation flawlessly runs unsigned code, there is a lot to expect from the work, and hopefully, in the near future, we should see a lot of additional news be released on the work. Great work guys, it's great to see there are still dedicated developers that are spending hours of hard work (over 60 hours on this project alone, as Fanjita states), to bring homebrew to all.
