Hello I have a Curve 8900 and have just fitted a new trackball and track ball cable assembly.
I have put back together properly without damaging anything with all connections right but when switched on the keypad does not work nor the volume,camera button .
Have i taken off a cable that has made the main board not recognised the key pad when plugged back in.
I have put old trackball assembly back in and is still tha same .
Any sensible suggestion would be helpful.Appart from buying new phone or hitting with hammer etc.
