Ipad 4.2.1 update unknown error
I had been trying to update my jailbroken ipad running on 3.2.2 to 4.2.1 for a few weeks now. I have downloaded the ipsw file and tried updating the ipad using shift+update multiple times. I keep getting the error message after verifying my ipad: The iPad "****" cannot be updated, an unknown error occurred (3194).
I cannot restore my ipad using a 3.2.2 ipsw file either.
I have searched different forums and used the apple support site, and found out that i was supposed to add 126.96.36.199 gs.apple.com to the host file. After that i tried updating again and after my iPad successfully entered recovery mode, the same error message appeared. Is there another way to fix this? Thanks in advance!
