Hi folks, I need your advice with a problem I have with my brand new PSP. I bought a brand new IC1003 PSP with 2.8 downgraded to 1.5. I can use it for a while but when navigating the menus or when in a game, it completely freezes (it does not turn off but instead the screen gets freezed with vertical lines on it). THE PROBLEM DOES NOT ARISES WHEN I AM SURFING THE INTERNET. It freezes after 5 or 10 minutes of use. I tried to use it without the UMD (Death to Rights), without the battery and without the 2GB Sony MS... with no results. I tried to upgrade to 3.30 OE, 1.5 and then back to 2.8, but it is always the same... it just freezes and I need to restart it. Can you help me please???
