iPhone 16 pro max bricked during update
Just received iPhone 16 pro max coming from 15 pro running 18.01. Went thru the phone to phone set up and was presented with need to upgrade 16 pro max to 18.01 before proceeding. Downloaded the update but then phone went black. Restarted phone and now it shows the splash screen before you can unlock, when I go to slide up to unlock it does nothing. I can't unlock the new phone at all and the back is getting warm. I have plugged it into my MacBook Air but it won't recognise it and have tied the volume button and power button restart but nothing is working. Im stuck on the unlock screen but can't unlock, please help
iPhone 15 Pro, iOS 18
