Before downgrading iOS, check signing status, back up your data, and confirm backup compatibility. Then choose TunesKit iOS System Recovery or Apple tools with a signed IPSW file.
The iOS version you want to downgrade to must usually still be signed by Apple. Unsigned versions cannot normally be installed.
Downgrading may erase your iPhone, so back up important data via iCloud or iTunes before you start.
A backup created on a newer iOS version may not be restorable to an iPhone running an older iOS version.
Use TunesKit iOS System Recovery to choose an available firmware version and follow the on-screen instructions to downgrade your iPhone.
Download a signed IPSW file, then use Finder, Apple Devices, or iTunes to manually restore your iPhone to a supported iOS version.

Yes, in most cases. Apple recommends keeping iOS up to date for the latest security fixes, improvements, and features. Make sure your iPhone supports the update before installing it.
