So , I used a combination of these solutions to “unstick” my iPhone 11. After I watched the video!
I plugged the phone into my MacBookPro and went through the restart sequence and then the next sequence to upgrade or reinitialize. I didn’t get through that when suddenly it restarted and responded once again. Still a little sluggish but I believe I accidentally downloaded a pretty large iCloud file 2-3GB when it started freezing up. I have a 128 so it wasn’t full but it’s not designed for huge file downloads. Maybe my new one will be able to handle it… thanks to “The Littles” 🤗
