So.... I installed the new lcd screen myself and it works fine. Only problem is it did not come with this black connector sticker/mat that lies behind the battery. So I was unable to connect my mainboard to the speaker, mic and charging socket area of the phone. I did peel the sticker/mat off the old lcd and connect it to the new one, but to no avail it does not work.
I really need help on what this mat is called as I believe this is the issue with the phone. Any help would be appreciated.. Please feel free to ask any questions.
Thank You Very Much
