Restoring iPad mini 1 no longer boots
On 09/04 iTunes 12.2.2.25 asked to update my first generation iPad mini, but during the restore it said "Your iPad can't be update; you must restore it to factory settings.". So I pressed "Restore" button, then it showed "Are you sure you want to restore the iPad "XXXX" to its factory setting? ...." I clicked on "Restore and Update" button. iTunes downloaded the update file and then showed "The iPad "XXXX" could not be restored. An unknown error occurred".
I clicked on "More Information" and try to follow the hostname manipulation solution and disabling firewall etc. but I could not get the "Restore and Update" on iTunes to work.
Before the update process, iPad was running without problem. Basically update process left iPad in broken state. Only thing I see on iPad it 'iTues" with white cable sign. I cannot operate on it do do anything.
What could I do to fix this so I can use it again just like before?
Thank you
iPad Mini, iOS 8.4
