Why is the touchscreen not working on my ipad air?

I just woke up suddenly this morning and I found out that my ipad's touchscreen wasn't working. It was pretty frustrating for me. I hard restarted it and i connected it to itunes but both of them failed to make the touchscreen work again. Do any of you guys know the answers? I would appreciate it. (Note: my ipad air is on 9.3.3 and is jailbroken and this morning I found out that the jailbreak ended and I'm not jailbroken for the time being.)
