Cannot restore iPad using icloud after IOS8 upgrade

The upgrade to IOS 8 was taking forever with no action on the bar bellow the apple log. After 4 hours, I did a hardware reset and recover the ipad using the iTunes.

So, I started to setup the device, choosing the ipad´s backup at iCloud.

The restore process begins

The blue bar stars to move

After just a couple of minutes the ipad restarts

Apple log appears with a progress bar underneath.

3/4 to the end it stops again

And stays stopped forever....

Please what more can I do?

Thanks for your help!
