better replace cristal ic work 100%%

1- if u remove cristal IC & short GND of Mic to GND of board & +
Mic to +Mic in "T230 Pic1", Mic will not work

2- & if u remove cristal IC & short Mic directly to point marked in "T230 Pic1", u will have low Mic but it work.

so better replace cristal ic from another SE phone like T230-T610-T68...

after removing MIC IC
make this links with shortless wires
I just test this solution and now is ready for all!

Use a 1k8 - 4k7 resistor for MIC power suplay
