2.)just reheat or resoldered the audio IC or cobba...???? test it.... still dropping signal..step3
3.)now u have to replaced a good audio IC... sp unlock and set faid.. test it again... u know that the IC is good but still dropping...go step4
4.)there are many solution on repairing that kind of prob....here's one of my final solution... first just reheat the PA and check weather the antenna switch pins are intact... if antenna switch is broken replaced it.. test the phone again.. still dropping...replaced the PA...u can do it mate gud luck
