as topic, i have psp button probs... it happened late last night.. i was playing some home brews and then when i turned off the brews and shut off the psp and turned it back on, the left shoulder key started to malfunction. i dont know whats going on. everytime i press it, it goes beserk like as if i was holding the key. on initial boot up, everything is fine its just when i press the left shoulder key it really messes up. when i play homebrews, becasue of the left shoulder key i cant use the home key anymore.
i reformatted my ms, downgrade - upgrade but i do not want to open my psp.. and its bought off ebay..
