How to install iOS 15.3.1 with this IPSW

Back up your iPhone SE to iCloud or your computer — restoring erases the device.
Turn off Find My in Settings → [your name] → Find My.
Connect the device with a cable and open Finder (macOS Catalina or later) or Apple Devices / iTunes (Windows).
Hold Option (Mac) or Shift (Windows) and click Restore. Choose iPhone_4.0_64bit_15.3.1_19D52_Restore.ipsw.
Wait — the device restarts several times. Don’t disconnect it until you see the Hello screen.

Stuck on the Apple logo? Put the device into recovery mode first, then restore.
