Ipad 2 stuck on apple logo with loading bar
I tried to update my iPad 2 to 5.1.1 and something went wrong. The iPad updated but it is stuck on the loading bar with the apple logo. The device is read on iTunes but i can't sync or anything like that because it is stuck. Can anybody tell me how to get out of it. The loading bar will not load and it is stuck. I tried restoring but it keeps on becoming stuck like before. Sometimes it will load to half way and stay there for days, sometimes it wont load at all. Sometimes iTunes also recognizes my iPad as an iPhone why is that? It says "itunes could not connect to this iphone because of an unknown error," what i don't have an iPhone i have an iPad 2. Someone please help.
