Once my mobile was dropped down and headed to repair centre and found that the Daughter board attached by a ribbon cable to the Mother Board was cut-off(ribbob cable tore away),...and now my headset jack,ambient sensor,volume buttons,ear piece,etc does not work.. Do i have any option of re-attaching the Daughter board back as before...? Please help me...
