Hi moonmoon290,

We also see that you checked out the Apple Support article If you see an error when you update or restore your iPhone, iPad, or iPod. To resolve the reboot loop problem, follow the steps in the Apple Support articles If your iPhone, iPad, or iPod touch won't turn on or is frozen and If your iOS or iPadOS device restarts or displays the Apple logo or a spinning gear unexpectedly. 

We hope this helps. 

Take care.
