I bought my psp as a 1.52. I upgraded to 2.0, downgraded to 1.5 (worked just fine). I recently upgraded back to 2.0 to get ready for GTA. Today after playing GTA I went to my photo folder to look at a wallpaper i downloaded and as soon as i clicked "Photos" I got a black screeen with some numbers on it (maybe similar to what I had to do to get the downgrader to work?) Now when I go to play GTA I get a message saying my psp is a 1.0. I'm thinking i left the overflow tiff file from downgrading in the photo folder, but is part of the downgrading process for the psp to think its a 1.0, and thus be able to update to 1.5? My other question is whether its safe to update straight to 2.0 now, or should I go to 1.5 first, then 2.0? thanks.
