To be honest, I have no idea why the Vita has been so impenetrable. I know little of it's security measures and that is what I'm interested in. I bought it day one and followed the PSP-mode scene bits and a little about Revitalize but since 3.18, I have stopped learning about it, only to check wololo on a weekly basis hoping for some epic breakthrough. Can anyone explain what has stumped hackers? In layman's terms of course.
