I was upgrading my psp from 1.50 to 3.03 E0-A and i was doing exactly what had to be done. Then by dog started barking and i went to go check up on him and i didnt notice the psp was still connected to the computer via usb. I sort of tripped and the psp crashed onto the floor while it was upgrading. I can boot it, i see the green light and everything stays on for a long time so i dont think its bricked, but i get a black screen cant do much after that. Any help would be appreciated.
