Rejuvenate

NOTE: Rejuvenate is deprecated, check HENkaku for all information on exploiting your PS Vita and running Homebrew

Rejuvinate was an exploit that ran inside the psvita's Playstation Mobile Development Assistant and Playstation Mobile Development Assistant for unity apps. which allowed you to gain Userland Code Execution, however it did not break out of the sandbox so it was as limited as offical sony applications are. the exploit was patched in firmware 3.52+, and all firmwares past this are not even able to run the PSM dev apps.
