After trying to put iTunes on a new iPad, we had issues that the iPad would not load iTunes as it was an older version. Tried to load the newest version of iTunes, but incountered a problem with iPad asking to restore to factory settings. In doing so, and updating the iTunes to current version, the iPad is now a blank screen. Tried to reboot several times as service desk said to hold down both the power button and round button until apple appears, then to let go of the power button and continue holding down the round button, but only to have the blank screen appear again and eventually turn off to a black screen.
Please advise as to how to restore iPad back and get iTunes to load back on the iPad.
