New iphone setup, software update interrupted,stuck on Hello screen
We obtained an erased iPhone 15 Pro from our daughter. I tried to use Quick Start to transfer data from my wife's iPhone 13 Pro. All was going well until it needed a software update. It went through this process, but stopped when a network connection was required. After about 30 minutes, I switched off and on. However, it will now not go past the Hello screen - the passcode page flashes up, then disappears, also the switch off page does the same. I let the battery run down, switched it on, no change. I attached it to my Windows PC Apple app via a cable, but it did not connect to the device. Have I irretrievably corrupted the software?
