[Moto X Q&A] Lamarrotems:
Obviously something went wrong. Messing with 4.4 is dangerous. I bricked mine but was able to follow some threads here and use RSDlite to unbrick. You should be able to find instructions on XDA or other places fairly easily on how to use RDLite to unbrick it. Just Google how to unbrick your (AT&T) Moto X. Make sure you follow the instructions for your carrier and year of phone as well as following every single step in the exact order. People often take shortcuts that logically seem harmless or like it wouldn't matter but it ends up being the difference between a successful root or unbricking.

I would uninstall every program and driver already on your computer, with restarts after every single driver or piece of software uninstall, re-download whatever the instructions call for, and start from scratch with the unbricking process (because obviously something got messed up along the way).

Once that is successful then re-read every single post on every thread on XDA and the first page of non XDA Google results concerning the root process for your specific mode. Make sure you didn't miss or misunderstand any warnings, steps, or processes. Then choose the best one and follow the process EXACTLY. You may even decide to once again do the uninstall/start from scratch process in between the unbrick and the second attempt at rooting - especially if they call for different drivers or (equivalent but different) pieces of software.

Double check all model numbers, versions of Android, and steps in the original process - obviously something went wrong (or more likely as in my case an ID10T error) since the original instructions you followed probably worked for nearly everyone but you (I didn't verify this, but assuming you used legit, updated, and proven rooting methods for your model and version of Android.

Did you read the first two paragraphs very very closely?
