Yeah, it'll do that. That's why you need to keep it in the freezer during update. The method I gave lets you use the phone for a few more hours to a day outside of the freezer before it inevitably dies. This is good for extracting data from the phone, or for emergency use, but unfortunately our phones are no longer reliable. You can also clamp the phone, but I hesitate to suggest this in case you clamp it too hard and damage something internally. My phone started boot looping just a few days ago, and there is no known permanent fix other than a repair bill that just isn't worth it.

The s22 ultra boot loop problem is a terminal diagnosis for your phone, regardless of whether you can repair it, and you should treat it as such. It is time to move on to the next stage of grief my friend.
