This tutorial covers how to upgrade ARK-4 CFW already installed on a PSP or PS Vita to the latest version of ARK-4! Although this is quick and easy, this does require you to have an already modified PSP running ARK-4 CFW or a PS Vita with ARK-4 installed. Once ARK-4 has been installed, any new updates to the CFW itself can be applied using the steps in this guide.
