Sometimes when replacing a screen or charger port we might damage the fpc connector by accident if it is not plugged in correctly or using the wrong prying tool ,But dont worry as it can be replaced and looks as good as new .
Firstly we unplug the battery
then remove all the sticky pads around the fpc area and protect any other FPCs or anything that might melt with heat resistant tape
adding flux on fpc and heat the area to remove the fpc
remember when putting a new fpc keep the tweezer away from the plastics on fpc as it will damage the new connector .
Any Questions Please
