I am trying to downgrade my iPad mini 2 to iOS 8.1.2 because iOS 8.1.3 doesn't provide anything better for me, so I want to go back to iOS 8.1.2 and jailbreak. But all the websites I tried for downloading ipsw, the download is way too slow. the progress bar isn't moving at all for about an hour. I have about 40mbps speed internet, so not really slow. Do you know where to download fast? Thanks.
