I was playing GTA(UMD) on my PSP and suddenly when i press square(brake) bec. im riding a bike, it didnt respond and suddenly whatever button i press doesnt work! i tried to turn it off but even the power button doesnt respond. The game is still running and i can still here voices and sounds. I waited for 2mins before i decided to removed the battery to reboot it again, but it doesnt turn on!! my version is 2.00 btw and the warranty has already expired and worst, ITS NOT MINE!!i just borrowed it from my cousin and he's rich and im not! is it bricked?is there any way i can "un-bricked" it?in a not expensive way.in from the Philippines btw.
