Guide

Real jailbreaks are always free and open source. Sites asking you to pay, install profiles or “verify” with surveys are scams.

Back up your iPhone 14 Pro Max 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 iPhone15,3_16.3_20D47_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.
