Step 7: You will now be shown the Firmware bundle customization page. Click on ‘General’ and press the blue arrow button to continue as shown below.
Step 8: In ‘General Settings’, you will find an option that reads ‘Activate the phone’. Check this option if you are NOT using an official iPhone carrier. Deselect the option if you are with an official network carrier. Press the blue arrow to proceed. Here you can also enable the multitasking, custom Home screen wallpaper, battery percentage indicator that officially not supported in iOS 4.1 for iPhone 3G.

Step 13: You are now ready to start the Pwnage process. Click on the Build button to select it and then click on the blue arrow to start the Pwnage process.
Step 14: The application will now prompt you to save your custom .ipsw file. Save the file in the Pwnage folder on your desktop. Save the file with a suffix Custom_Restore so that you can easily identify it. The IPSW file will take close to ten minutes to be completely built.
Step 15: You will be prompted to enter your administrator credentials. Enter the details and click ‘OK’.
Step 16: You will then be prompted if your iPhone has been Pwned before, click on “No”.

Press and hold the power and home buttons for 10 seconds.
Then release the power button and continue holding the home button for 10 seconds.
Once your iPhone is successfully in DFU mode, PwnageTool will prompt you to launch iTunes.

Step 19: While on the iTunes window, hold the Alt/Option key and click on the ‘Restore’ button. (This is a VERY IMPORTANT STEP as just pressing the “Restore” button will result in restoring your iPhone with the latest firmware, which is iOS 4.1 firmware currently, by holding down Alt/Option button, allows you choose the custom iPhone firmware file).
