What causes the restore screen on the iPhone XS Max?
So my iPhone has had this message on an all black screen: support.apple.com/iphone/restore. My phone does not turn on or update using the methods seen on YouTube. I tried to restore it but that also didn't work, it gave me the unknown error screen when I tried to restore it. I am going to get a new phone tomorrow but I just want to know why does this happen to an iPhone? What could have caused this and why wouldn't it even let me restore the phone all together?
Thanks
iPhone XS Max, iOS 13
