This is not working

When i got home yestreday my ipad battery was almost emptu and it was saying authoziezation failed and rebooting over and over again. Now its in a loop and will not work. I have tried to restore, I have tried to manually update the firmware but it is stuck in this continuus loop. I have tried to authorize via wifi and itunes. Same issue. I am have an ipad1 wifi. Why did my computer get patched? I did not install anything. How can this just start out of the blue? Please send me a solution to this problem.

Thanks.
