There is a small golden square that fell out during the teardown
So I was doing a teardown because my phone suddenly blacked out and no matter what I did, the screen wouldn't turn On, I tired all the manual reset techniques. Only the led was working to show that the phone was charging. I opened the back and tried unplugging and plugging all the connectors and I put everything back and then I realised that a very very tiny golden square fell out and so I opened it up again but didn't know where it was supposed to go. I tried charging it without this tiny piece but this time the led didny work either.Can someone please help me with This?
