• If you are downgrading (e.g., from iOS 17 to 16), click the version you want.
• Click the "Flash" button.

• Official vs. Custom IPSW: Pro Flash supports the flashing of "Custom" IPSWs (often created via tools like Sn0wBreeze or PwnageTool). These custom files typically include pre-installed Cydia (jailbreak) or modifications to the root filesystem.
