Unable to factory reset after unroot

Hi everyone,

I rooted my Padfone X, unrooted it, and now when I go to try to do a factory reset, it just hangs at the Asus logo after the reboot. If I hold the power button down, it will boot up fine, but all my info is still on the phone along with all the apps from google play.

I also tried holding vol down and power button and it also just hangs there.

I just want it back to the original rom. how would one go about fixing this issue. And I did not make a customer recovery because I did not remove anything from the Padfone x, all I did was root and unroot.

Thanks everyone.
