The next step is to restore your iPhone 3G with the custom firmware IPSW file that you downloaded. For this, you will need a Mac computer with iTunes installed and a USB cable to connect your device.

If your Mac asks you to install a device update, click on "Install".
Wait while your device downloads and installs the update. This may take several minutes and your device may reboot several times during the process.
Once the restore is complete, you should see a message saying "Your iPhone has been restored to factory settings".
You can now set up your device as new or restore it from a backup using iTunes or iCloud.
