Recently while upgrading my friend’s iPhone 4 to iOS 5, I was facing error 14 in iTunes. I tried to restore a couple of times. I even tried by putting the iPhone in pwned DFU mode using iReb. But no success.

I googled the problem to find the solution. Error 14 in iTunes is caused because of a corrupt iOS 5 IPSW file.
How To Fix Error 14 in iTunes?
Note: This solution works for all iOS versions (iOS 5 & earlier)
If you’re upgrading to iOS 5 via iTunes directly:
1. Delete the previously downloaded software update file which you will find in this location depending on your system:
Mac: /users//Library/iTunes/iPhone Software Updates
Windows XP: System Drive:/Documents and Settings/Application Data/Apple Computer/iTunes/iPhone Software Updates
Windows 7: System Drive:/Users/Your Username/App Data/Apple Computer/iTunes/iPhone Software Updates
If you faced the error while upgrading your iPad or iPod, the last location path will change:
../iTunes/iPod Software Updates or ../iTunes/iPad Software Updates
2. Now, restart iTunes & begin the update again. This time iTunes will download a fresh copy of software update file.
If you’re trying to restore by using the downloaded iOS 5 IPSW file:
1. Re-download the IPSW file.
2. Now, restore to this newly downloaded IPSW file via iTunes.
