Since, the announcement ten days ago, Rejuvenate received tons of positive reception and thousands of downloads. Progress on both SDK projects is moving at fast speeds. There are already Vita homebrew projects in the works. No doubt, there are more to come. However, Sony’s response has not been positive. Yesterday, Sony released firmware 3.52 which revokes access to PSM DevAssistant and PSM Unity DevAssistant along with a friendly request for PSM developers to delete the DevAssistant from their devices. This means that if you ever want to run homebrew on your Vita, regardless of your opinions on the current limitations and regardless of your ability to use PSM, do NOT update to 3.52.
The following was taken from a series of unpublished posts I wrote back in September 2012 (almost three years ago). The posts not only detail the exploit I found but also the thought process that led me to it. I intended to publish it as soon as the exploit was patched by Sony or after someone found another exploit on the system by examining the memory dumps. However, as of today, the PSM privilege escalation is still the only known way to execute native ARM code on the PS Vita. Apologizes for the outdated references.
(Sadly, they did not give me a spot at the Sony E3 conference, so I have to make do with this blog post.) I am excited to announce Rejuvenate, a native homebrew platform for PS Vita. The tools that will be released through the next couple of weeks will allow developers (not in contract with Sony) to develop and test games, apps, and more on the PS Vita. These unofficial software can run on any PS Vita handheld device without approval by Sony. These tools cannot enable pirated or backup games to run (I’m not just saying this… the exploits used does not have enough privilege to enable such tasks). Rejuvenate requires PlayStation Mobile Development Assistant to be installed on your Vita! Sony will remove this from PSN soon, so if you wish to ever run homebrew apps on your PS Vita, you must download this app now!
