3.5 iPhone Stuck in Boot Loop during Downgrade

Your iPhone may stuck in boot loop while downgrading iOS 16 due to insufficient free space, corrupt IPSW file, incomplete update, etc. The easiest solution here is to force restart the device to fix some minor errors.

Data loss is a common problem during the downgrading process. That’s why we strongly suggest you backup iPhone/iPad data before you do the entire process. If you already have a backup, you can restore the lost data easily.

What if you didn’t make any backup and lost your important photos, videos, contacts, messages, WhatsApp, etc. Don’t worry. You still have the chances to retrieve them back.

Fucosoft iPhone Data Recovery software is an efficient tool that helps you recover different kinds of file directly from iPhone without backup.
