Nokia X1-01 lost mic

This line loses a regular mic, you will replace the mic, there is a case of forever change, if the circuit or ic error will be a lie when doing it, before changing the mic or you cannot check the total number at 3 points 1 2 3 see how it will be, if you lose the sum of points at points 1 and 2 you will have to redo the ic foot, if you lose at point 3 then you will score 3 with 4 together.

Good luck!
