I have a PSP 1000 with cfw 5.50 gen-d3. (i think thats the cfw...) I've fixed my psp because it wouldn't load up due to the screen. I gave it a little test and i figured out the buttons on the bottom of the psp wouldn't work. I replaced the strip a few day later and gave it another test. All buttons work however the start, select and the other two buttons next to them won't work. I tried cleaning the insides, no luck. Unplugged and plugged it back in. Nothing seems to make it work. Does anyone know how to fix this?
