i think no... (but backup the act.dat file) the type of activation is never changed on vita and the file act.dat is the same for all version, i think... but i am not sure about thath... (don't do anything for now, wait other user...)
well, exist a metod to active vita (with e-psp bubble 2.0((old)) or MLTactivator ((new)) ) this type of activation is not good you risk a device-bann form psn and some problem ( not in all cases) and not work for all...
