Phone would not turn on with power attached. After 10 minutes back of phone was still cool. Customer stated this took place after a digitizer replacement done not by our store.
Replacement went went fine. Only issue was the old adhesive under the battery ripped and was difficult to get off. I was able to finish the removal using a iOpenier and applying heat to the backside of the phone.
Make sure to have something to keep all of the screws in order while taking the phone apart.
