Wiring Diagram For Microphone, Please.

Feb 14, 2016
Hello everyone!

I've made a mistake during cleaning my Hongmi... I used something like "contact spray", to clean USB socket.

After this, my bottom microphone doesn't work. I've flash with SPFT, I've flash with stable V5, V6 and V7 rom... but nothing helped.

I've also changed USB PCB - but again without success.

So.... I really wonder what I can do more? I would like to check where microphone paths are going and if they are ok.
But for this purpose I need wiring diagrams, anybody can share?
