Ok I am not a veteran in the psp world, but I am not a noob either...
whenever i try to start the 5.50 GEN D-3 updater, my psp screen goes blank and i am lost on how to make it work... I only wanted to update my psp in order to play MHP3rd Demo
and to do that I have to update it from 5.00 M33-6 to 5.50 GEN D-3 and install Prometheus
any ideas on how to fix, or a tool to help play the demo on 5.00 M33-6
