回答“Power button won't work after wifi & screen replacement”Unfortunately, I’m having the very same problem now…. When I tearing off the digitizer, the wifi antenna and on/off button was ripped off. I ordered both ribbons and replaced them very properly, everything works but the on/off and volume down button doesn’t, I’m not sure why, any solution guys? I’m really confusing now as only the volume up button is working…. Why? What a pathetic situation!
