Hi there, I completed the battery replacement nicely with all your steps, the phone could turn on and function normally, the only issue after the battery replacement is the phone has no sound and vibration. I have ensure all connectors are back to place securely. Does anyone have any clue of the cause of no sound and no vibration?
