Iphone 12 stuck in boot loop, won't update or restore

My iPhone 12 was stuck in a boot loop and would not hard reset. I put it in recovery mode and connected it to my iMac, but it will not let me update or restore it; I keep getting an unknown error 4013.


I've tried all sorts of trouble shooting and am out of ideas. Any advice?

If you have already spent way too much time working your way though this Apple Support document.....If you see error 9, 4005, 4013, or 4014 when you restore your iPhone, iPad, or iPod touch - Apple Support.....it is time to make an appointment at the Apple Store or take the phone to an authorized service shop.
