Connect the device with a data cable and run the newly installedXcode, Go to the menu Window-> Organizer, click your device, and select other version from the software version drop-down menu to open the downloadedIOS4GM, and then click restore. It will be installed after confirmationIOS4. Because all data on the device is cleared, you must back up the data in advance. After the device is installed, no standby screen is displayed, because iTunes is required to activate the device. Exit xcode.
