You had mentioned the phone running hot if the battery wasn't disconnected in the correct sequence, how is this resolved? Also, the phone after lcd assembly replacement is unresponsive, I have gotten a dinging sound that repeats but nothing on the screen...iTunes recognizes the phone but I get nothing on the screen, I've tried reassembling several times with no luck, this is not my phone, I've done many repairs on iphones in the past
and never had this problem...please help, it's an iphone 5s
