Most key pad freezing problem,could be solve by software.If some of the keys are working it is then you need to use another working board to compare a link that is off,but in this case,do some ultrasonic cleaning,rehot board, and then try to flash phone. :)

try coupling your phone , this application is caused by case interruption on your phone.
try this now.
