iPhone 11 Pro Max IPhone keeps hanging, crashing, and restarting/rebooting in a loop, non-stop since Monday

[MikeX]

My iphone keeps rebooting and then after i login about 15-20 secs later it freezes. and after it crashes and reboots again, all the changes i do are rolled back.

this continues in a loop forever.

if in these 15 secs i manage to change anything e.g. a setting or even delete an app, it is rolled back after the freeze.
if i do a change and manually shutdown by pressing vol down+right button then after it reboots, setting stays.

It is an iphone 11 max pro. I have IOS 15.4.1. i installed it on the first days and everything was fine. this is only happening for the last couple of days.

Anybody has the same issue? what can i do?

I would take it to Apple to have it checked.

Just wanted to add that I am experience the exact situation you described above but with an iphone 13 Pro Max. Can’t restore or update from a pc or Mac and only have a few seconds to grab details before the device freezes.

Apple tele support couldn’t help so l’ve booked an in store appointment to get it replaced under warranty

Went through this tonight on my 12 Pro, running 15.4. After an hour of attempting to reset via Settings, or get into Restore and DFU mode, I managed to get signed out of Find My, which then let me go into Restore mode. (When Find My was on, if I tried to enter Restore, the phone just restarted.)

Pain in the butt, and no idea why this would happen. Thank Apple for iCloud backups.
