Hi, my problem is when I try to plug the iPhone 8 battery into FPC, you can’t stand right after the hands are lifted and there was something minus the Ka installer. It cannot be fixed within FPC
This is becoming a common problem on the IPhone 8. It is the FPC on the board that is causing the problem. Sometimes you can manipulate it to make the battery FPC fit snug but other times you need to replace it.
are you 100% sure the battery is the correct model? that might be what’s wrong. otherwise, check if any of the metal pins on the fpc connector is damaged. make sure to align the cable above the connector perfectly. it may take some time, as it can be really tricky
New battery have sometime that problem or many time battery connect and disconnect process makes battery contact loose to battery connector. Simply bands the pin on battery flex and cover with small tape and screwed well.
