Indeed in order to install these 2 eCFW PSP on your Ps Vita you need to have a bubble PSP on your console (games, demo any) but without psn, it is now almost impossible to recover a demo or a PSP games Without making many and dangerous manipes.

Here is Celeste_Blue, member of our forums, with his new homebrew: ePSP Bubble Installer.
After a first homebrew in collaboration with other devs, it returns with this new homebrew which will allow you to create a bubble to install then Adrenaline or even Ark (and even other homebrews requiring a bubble PSP).
This homebrew comes in the form of .vpk, which you install with VitaShell or Molecule like any other .vpk. In addition it allows Celeste_Blue to participate in the competition Gekihen (link here) which as a reminder has been extended until March 19, 2017. Good luck to him ... and all the other participants ...


Description:
A tool that quickly creates a mini ePSP bubble for use with Adrenaline or ARK.
