Stuck on Bootlogo After Upgrading to iOS 8.1 can't enter recover/dfu mode I upgraded my iPhone to iOS 8.1 with iTunes, after the update my iPhone 5 is stuck at apple boot logo. I tried to enter into the DFU Mode but the screen still stuck on apple logo. I also tried to enter recovery mode but i couldn't.

How can I unbrick my iPhone ?

P.S My Sleep button is not working
Well a sleep button would be nice but without it I don't think there is a way of fixing it. Does it show up in iTunes? I guess not. Just go to an apple store and let them fix it. (And if you don't have AppleCare that should not matter since it is clearly their fault)
