Jailbreak

No public jailbreak is known for iOS 17.4 on iPhone 15 Pro.

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

How to install iOS 17.4 with this IPSW

  4. Hold Option (Mac) or Shift (Windows) and click Restore. Choose iPhone16,1_17.4_21E219_Restore.ipsw.
  5. Wait — the device restarts several times. Don’t disconnect it until you see the Hello screen.
