Installing ARK on PS Vita Firmware relies on the recently revealed email hack, the same thing that was used for the Playstation TV hack (whitelist).
The idea is that you are going to “inject” ARK into one of your existing PSP games on the PS vita.
Alright, let’s make things clear: the process to get this to work is fairly complex, and requires lots of manual steps.
Hopefully at some point people will automate some of this, but this is what we have for now.
An update to the PSP® system software was released on January 15th, 2015.
You can use this update to upgrade your system software to version 6.61 (including 6.60).
Important note: the following guide is valid on all regional variations of the PSP 300x: PSP 3000, PSP 3001, PSP 3002, etc… Installing a Custom Firmware on your PSP 3000 has never been so easy.
In this page I’m describing the easiest possible way for you to install the most reliable Custom Firmware on your PSP: Pro CFW.
But the community (read: hackers) did not accept defeat.The current version of the software, 6.61, was made available on January 15, 2015.It is a minor update released more than three years after the release of the previous version 6.60 in 2011.Instead of enabling people to run homebrew, the PSP hacking groups have started building their own PSP custom firmwares.Their firmwares are nearly identical to the official ones, only better.The battery must be at least 50% charged or else the system will prevent the update from installing.
