Default [Q] sgh-i527 no touch response after 4.4.2 update.

I have a at&t mega i527. A few days ago. I pressed update and it updated. I eyed to take the battery out before it would compete and now the touch screen is not responsive. I have tried everything. . Kies. Odin. Adb sideload. Nothing had worked. I even replaced the screen. Nothing I try had worked. Does anybody have any ideas thati could try. I feel like I've tried everything. Any ideas or help will be greatly appreciated
