I was installing custom firmware about two weeks and after I played my game then I shut it off .The next day I tried to turn on my PSP but it won’t turn on I tried charging it without a battery but it didn’t work plus the power indicator was straight up black no green light or orange just black. pls help me fix it

Hi! Looks like the system is bricked… Or your power board died. It could be multiple things. Can you try to boot with another battery? Otherwise we need to open up the system to test multiple components.
