My display was not turning on and my home button was not working (I verified this by trying to activate siri which didn't work). When I replaced the display assembly everything works except for the home button. Since this assembly comes with the button and the ribbon cable, I'm not sure what else can be wrong. I checked the contacts on the phone and I see the little copper 'pins' sticking out. I can't tell if they are making contact since the display has to be closed, but it appears they are lined up correctly. Does anyone have any suggestions or ways to test the contact pins? Could the home button on my replacement be defective? I've already emailed support, but just curious if anyone has any suggestions I could try while waiting to hear back from them. Thanks! By the way, SUPER grateful the rest of the display works. I can now back up my phone and can probably deal with a broken home button if I need to. Woohoo!
I just wanted to mention that the battery can be VERY DIFFICULT to pull out. I used the plastic tab, but it broke off. I was forced to pry it out, but like I said, it didn't come out easily and the battery was all mangled by the time I pulled it free from the adhesive. This guide tells you where to pull and where to be careful, but it still made me very nervous! Just keep working at it if yours is also stubborn.
