Hello, I made several repairs on this phone, When I changed the Vibrator cable the phone stopped turning on. I started analysing it and nothing was wrongly assembled, then I compared the motherboard with online photos and saw that one of this 3 components marked inside the red circle is missing, I might have slipped the screw driver on it and removed it accidentally. I cannot identify this component, can someone pelase help me?? It's been a long time since I used this phone because of this... Thank you.
