Well, it happened once again! To all of us who upgraded our PSP's a group of people found a new bug and successfully exploited it.
This exploit will work on any version of the PSP that is able to see tiff images. For now, the exploit shows a screen with a message known by the majority of users as “hello world” as in every programming language.
This program shows that we can actually run code on the PSP without the GTA game. Announces have been made and it seems all there is left to do is code an eLoader to be able to load homebrew on our PSP's without the need of a GTA game.
Kernel mode is available in versions 2.0 – 2.71, in which 2.71 will take a little extra work and by consequence some more time. This will bring the possibility to a downgrader, but as fanjita says on his web page, why downgrade if you have kernel mode?
You can download the files here. Inside the zip there are instructions to use the program, although it is very straightforward. Also inside the zip you'll find a file with more information about the discovery and all the acknowledgements.

That's it for now, but keep coming because I will have more news, tutorials, and many more things!
