2. Plug your device into your computer
3. Turn off the device by holding the Sleep/Wake or Power button and swiping it off
4. Hold the power button for 3 seconds
5. Begin holding the Home button without releasing the Sleep/Power button for 10 seconds
6. Release the power button and continue holding the home button until you get a popup from iTunes that your device is recognized as being in recovery mode.
7. Now hold down the (Mac Option/Alt) (Windows: Shift) Key and click on the Restore button. In the navigation sheet that appears locate the ipsw file you just downloaded and click Choose. Again, this will wipe out all the data on it so be sure to have a backup.
8. Be patient and wait for the installation process to be completed by iTunes
9. Once the restore is completed you can select your backup or treat the device as a new device.
Heres another important note (which Windows users should pay particular attention to; also, this is something that only applies if the user chooses to look for the desired IPSW file on the Internet). Your browser may change the IPSW file into a .zip file. For example, Microsofts Internet Explorer does this, if used to download the firmware bundle. This doesnt mean its unusable. Instead of wasting time switching web browsers, just rename the file to end in .ipsw and iTunes will accept it.
For Restore and if the Device times out:
If your device times out during the restore sync after the software is reloaded back on, uplug the device via USB and replug it back in. It should then continue to sync again.
