"Stuck on White Screen and won't restart: I have an Iphone 13 pro max, it is stuck on a white screen and will not do a hard restart. I also tried to restore with my PC but it keeps erring out. Any other ideas? I'm waiting for the device battery to run out naturally hoping the power off may help?"

Troubleshooting a White iPhone Screen:

Try Swiping-Down from the top-right corner of your screen. See if that rids of this window. If not, I'd say the iPhone is stuck in a boot loop(because it was updating), or is simply frozen. So, if swiping down does not work, refer to the following... Refer to my User Tip: How to Fix an iPhone in a Boot Loop - User Tip
