I have brand new iPad touch 4th generation! started setting up using Mac. While reading legal part could not go back in the menu to press continue button. Using iTunes. I charged ipad touch 4th generation, then connected it to Mac using usb, then itunes, in the middle of initialization, wandered off reading terms and conditions and reading legal part in blue, it redirected me to a new site or in a different direction of the set up, I could not go back to press continue, because there was no button continue. ipad touch turned on briefly no software was loaded, or maybe some was loaded at that stage, then it switched off by itself, I did not touch it in anyway when it switched on, After it swiched off the screen has become black. Probably locked. It does not respond in anyway. And when I connect it to Mac and itunes. The mac does not show that Ipad touch 4th generation is conected. Ipad touch 4th generation is a previous model that is not sold anymore. It is 2012 model. Please help me to initialize it or switch it on somehow! Because it is definetely not brocken! I need to make it switch on or restore it!

Please help! Now!
