For what it's worth, I've been going through some misery over the past few days. I let my XS Max phone update to the latest IOS a couple of days ago before I left to make dinner. I returned to my phone an hour or so later and noticed it was in a boot loop.

Fast forward 2 days later:
I've watched a bunch of YouTube videos, read many web pages on how to get out of it. I've gotten the phone into recovery mode, hooked it up to my MBA with Mojave, updated firmware, no success. I bit the bullet and gave up everything stored on my phone and did restore: It seemingly worked: I got the white Hello screen, went through full set up, then about 5 minutes into feeling good about getting my life back together, it abruptly shut off and the boot loop problem came back.

I've gone through this process a few times and it keeps coming back. I've tried zipping through the install screens and doing a normal shut down. Didn't work. I've tried this with and without the SIM card in. No difference.

I'm amidst another novel approach:
I updated one of my Macs to Catalina and tried restoring again using the "new" way MacOS syncs with the iPhone (ie not using iTunes). It's been about 20 minutes and the phone still hasn't gone back to the boot loop.

This article was the first I'd seen online with this problem on an iPhone XS Max.
