Last evening i tried to do a firmware update to my ipad 2. It was running on 4.3.x and I decided to go for IOS 6. SO I downloaded the new Itunes (the ;latest one) It asked me to backup my 57 GB on the ipad. It downloaded the new IoS software and in event of updating I don't know what happened and finally an error occured saying that the device can't update. Now, I what i see is a black screen with Itunes and the USB cable showing to connect to it. Please help me...I don't know what to do to bring this back to life. I am certainly feeling a bit bad about the upgrade.. thanks in advance.
