I replaced LCD assembly because of broken glass on iPhone 7 plus. When removing the home button one of the ribbon cables tore. I reassembled the phone with new LCD assembly and then the earpiece speaker didn't work. I then installed a new front camera cable and home button and now phone goes into a boot loop, and customer says that his battery life is terrible. I've tried going back to the factory LCD with damaged glass (other than broken glass everything worked fine) and also reinstalling factory camera cable. I still have no sound on earpiece (speakerphone works) and the phone will not boot with the new home button or the old home button (with the torn cable installed)...it will boot with no home button connected, but still no earpiece sound. I have tried the solution with the little piece of black tape to no avail. I would just refund customer but when I got the phone everything worked fine, just had cracked glass. I'm afraid I'm gonna have to buy this guy a new phone! Any info is greatly appreciated.
