PSP firmware 2.80 kernel access exploit found
Posted by multippt
Team C+D recently discovered a way of running homebrew applications with kernel access on firmware 2.80. Previously, there was no known way of running homebrew applications on PSP firmware 2.80, and that homebrew applications will only run on user mode on the PSP. This exploit runs on the currently available TIFF exploit on the PSP. At the moment, only a proof of concept of the new exploit is available. This “proof-of-concept” application dumps the firmware of the PSP to the memory stick
This exploit meant that it is possible that a PSP firmware downgrader for firmware 2.80 may emerge in the near future. Kernel access also meant greater support for more homebrew applications, especially those which run in kernal mode.
