I bought an IPad mini with a passcode and I tried many times to restore to factory and I always got errors like 3194, I believe. Restore failed on several Windows 7 laptops (by putting the iPad mini2 into recovery mode because the IPad mini2 would not go into DFU) that I have and I was finally able to restore to factory using a Windows 10 machine which is just crazy but nonetheless it worked.
