I am using the Redsn0w jailbreak tool for my iPhone 4, but I keep receiving an error message stating 'missing keys.plist data for this build'. How can I resolve this issue?

The 'missing keys.plist data' error usually occurs when Redsn0w does not recognize the firmware version on your device automatically. To fix this, you need to manually point Redsn0w to the correct IPSW file. Open Redsn0w, go to Extras, then click Select IPSW. Browse for the iOS firmware file that matches the version currently installed on your iPhone 4. Once the firmware is successfully identified, you can go back to the main menu and proceed with the jailbreak process.
