i am trying to fix a friends psp, but i tried a bunch of ideas and none of them work. he loaded a cso (yea i kno, it wasnt me) on to his psp but it didnt work so he deleted it. then whenever he put a umd in the drive it would say "the disc could not be read". then it started to just freeze and crash everytime there was a umd in the drive. i remember seeing the "disc could not be read" message when i first downgraded from 2.6 -> 1.5 so i tried hard rebooting it and reseting the registry. tht didnt work :Cry: so i tried reinstalling his firmware, 3.03 oe-c. didnt work either ... has anyone else run into this problem?
