I've seen a lot of videos claiming they could install install VHBL on any version from 3.60 to 3.69, through PSP or PSP mini demo or full game exploit, copying the game to PC and then patching it and putting it back to PsVita with a VHBL save file, but I tried it myself without success, I just wanted to know, and with anybody has succeeded doing this process and or if is there a way to do it or something else we could do, please share it here.
