How to Extract IPSW From iTunes (6 Steps)

Launch iTunes by clicking its icon on the desktop.
Connect your iPhone, iPod or other iOS-powered device to the computer using its USB cable. ITunes will automatically add it to the 'Devices' list in the left-hand column.
Select your iOS device from the 'Devices' list and open the 'Summary' tab. Click the 'Update' button followed by the 'Download Only' button in the dialog box that pops up. This will download the latest IPSW file from Apple to your computer, but won't install it on your iOS device.
Open the 'Home Folder' on your Mac and navigate to the 'Library\Application Support\iTunes' folder. On a Windows PC, open the 'My Documents' folder and navigate to the 'AppData\Roaming\Apple Computer\iTunes' folder.
Click the folder that corresponds to your iOS device to open it. For example, if you downloaded the IPSW file for an iPhone, open the 'iPhone Software Update' folder.
Right-click the file that has an '.ipsw' file extension and select 'Copy.' Open the folder on your computer that you want to extract the IPSW file to, right-click anywhere inside the window and select 'Paste.'
