While trying to set up a new iPhone 6,
I've went through setting up a passcode and fingerprint process.
I've asked to restore from iTunes backup.
Than I confirmed to iTunes to upgrade the iOS version on the iPhone from 9.0 to 9.1.
After a while, the iPhone stuck in a stage that the screen turns on in white and at the bottom there is a message: "Slide to upgrade"
Any sliding on the screen doesn't make any effect on the iPhone.
The iTunes show a stage 5 of a syncing or upgrading process, that doesn't come to an end.
Trying to restart the iPhone (by pushing both Home and On/Off buttons) end at the same stage of white screen with "Slide to upgrade" message.
HELP Pleas.
