iTunes errors - corrupted updates and error 14
So I'm trying to update my iPad mini 1G from 7.1.1 to 7.1.2 but iTunes cannot download the update firmware without corrupting the download. I tried 14 other ipsws from other websites and iTunes will either hang during the update (30+ min) or when the progress bar reaches the end iTunes will give me error 14. I've tried looking in the forums but nothing helps, I've reinstalled iTunes on my Mac, I've used three different cables to fix error 14: nothing works. Here are my specs:
OS X 10.9.3 (Mavericks)
iTunes 11.2.2 (3)
iPad Mini 1G 7.1.1
