Flashing other carriers firmware on a moto X is not a great idea, unless you KNOW it to be safe. And also remember on the X, trying to downgrade from 4.4.2 or higher, can lead to a brick....even a permanent brick.

Here is a thread that may help....

You can ask for further help in that thread also.

Hope you work it out!!

This is another option to try. But no matter what method you try, you MUST use the firmware for YOUR device, not a different carriers....and the same android version you were on. Again....DON'T downgrade a Moto X that is on 4.4.2 or higher already....ever.
