I Forgot passcode on my IPad. Downloaded iTunes, restore to factory failed, with error message '''0xE8000015'''[br]
Not until I disabled the firewall on my Windows security did I get to the next step Ipad Recovery Mode. [br]
while on IPad Recovery mode you will see a bar in tunes, on the top screen that will say “Extracting Software” . You will be able to monitor the process.

*This is a lengthy process*
