i don't wanna use mltactivator because I have 2 psvita and one is the clone of the other one (i copied my psvita's memory stick content to a sd2vita's microsd). now I have two equal psvita, one with a working version of adrenaline, one with a not working version. adrenaline recognises my second psvita as activated because it keeps me going on during install process. after installed it gives me error. i don't know.You see I had the same issue and it was a activation problem I used mltactivator and I was missing a line in the config and file placed in the tai folder.
