Won't charge after new battery
Replaced battery that customer thought battery was dying and iPad mini was fine. I had lock screen with home picture and pin came up so I knew it was good to go. I plugged it in and went to bed. Next day I went to check it so I could deliver it and it had not charged at all. I can plug it in (with OEM cable and block) and I get the flashing low battery and lightning symbol but it never charges. Thoughts?
