I have iPad 3 (model A1416 Wi-Fi only). It was using iOS 5.1.1 and I have then jailbroken it.
Unfortunately I allowed the device to update automatically, and didn't save the SSH blobs or any other files to enable be to revert the OS back again.
After trying some restores, I now get the black screen that tells you to plug your USB cable and connect with iTunes.
iTunes says that I have the last update and no update button is available, only restore
I have download some IPSW files for iOS 5.1.1 and iPad 7.0.4, and if I try to restore with shift in windows and browse for IPSW files and extract it, I get an error that I need to check host files etc
I have downloaded many tools like iFaith and take SSH keys from Cydia for iOS 5.1.1 and trying to make an IPSW from that give me this message:
The provided apticket looks valid!
Although the apticket is valid, the set of blobs you selected are not supported in this build of iFaith.
So, I am unable to put either 5.1.1 or the latest iOS on my iPad – how can I fix this?
