iphone 12 flashing apple no boot
Just took delivery of an iphone 12, the very next day it wouldnt power on. Apple logo flashes when plugged in. Managed to get the restore screen up when connected to my laptop, itunes downloaded update files to do a system restore but the iphone keeps dropping its connection to the laptop and itunes cannot proceed. Have an appointment with apple this afternoon as at&t told me it had to be a warranty claim as wouldnt return it without it being restored otherwise will have to pay full amount of the phone.
I have a feeling apple is going to want to send it away with me leaving without a phone. Anyone else have a similar experience and able to share insights/guidance?
Thanks
