Yifan Lu - PS Vita: The Progress & The Plan

A while back I reported a project started by PS Vita developer Yifan Lu. The project is called UVLoader (Userland Vita Loader) and would serve as a homebrew loader running natively on the PS Vita. Yesterday Yifan Lu has broken his silence regarding UVL and the PS Vita in general. In his blog he sheds some light on 'hacking' the Vita and highlights what needs to be done in certain areas of the Vita's security levels. Also stated is that without a open SDK for the Vita, his complete UVLoader would serve no functionality to homebrew developers and users alike. So his current exploit will be kept under wraps and rather serve as a focal point to learn more about the PS Vita and the possibility of finding other exploits. Here is an extract from his blog.

About PS Vita - The Progress & The Plan:

Sorry that it’s been a while since I’ve said anything about the Vita. I was caught by surprise the last time of all the media attention from just a simple call for help. While I still don’t want to say too much right now, I do want to answer some common questions I’ve been getting and also go over what needs to be done.
Did you hack the Vita?
That’s a very vague question. What I have done, is run native code on the Vita with the same permissions as the game being exploited. This means I can load homebrews written and optimized for the Vita’s CPU and take full advantage of the CPU speed and RAM (unlike the PSP emulator or PSM, both impose artificial limits on resources and system functions). What has NOT been done (yet) is unlocking the system completely for tasks like USB interfacing, custom themes/system mods/plugins, and (fortunately) pirating games.
