I have a iPhone 8 64GB and it was accidentally unplugged whilst a ITunes IOS restore was going on and I’ve tried following online steps by plugging the phone into a pc then pressing the volume up then the Volume down button than holding the power button but the phone still doesn’t want to boot and I can’t find a way to get the phone to boot and I need some help to get the iPhone 8 to boot.
