From my experience, I would say yes. But it was my first time trying to fix one of these and it probably depends what cause the issue in the first place... I think. In this case it was probably bricked due to a failed mod attempt. I took a gamble when buying this.mines is a 3g model ps vita, no internal memory and it did work. The 1gb of internal memory comes during the process of modding it. I hope that this will fix any vita that has a blue light black screen issue but, who knows. I going to make another video hopefully giving a better explanation of what I did. Sorry for the long reply.
