Same thing happened to me but i learned the hard way that you should never take a OTA update while rooted because it screws things up and the phone is not stable enough to run Android OS without crashing and rebooting again. So what i did is i used RSD lite to reset to stock and after making sure root was gone i took the OTA update and now my DROID ultra is working fine . and FYI if you still want root when running KitKat use slapmymoto to keep root it requires you to have 4.2.2 already installed and then follow some steps so you can keep root in KitKat hope it helps!
I have a Droid Mini too and followed this guide. Now i have a rooted Droid Mini with Kitkat.
If he is already on Kitkat, then you are right of course!He forgot to disable write-protection (http://forum.xda-developers.com/show....php?t=2551113) and flashing back to the camera update (12.5.5) and using SlapMyMoto (http://forum.xda-developers.com/show....php?t=2538896) before the Kitkat update.
What version of RSD Lite did you use? I've tried 5.6, 6.4, 6.5, with different USB cables including the one that comes with the phone but I cannot get RSD Lite to recognize my device. I tried fastboot as well but it keeps giving me an error about missing XML files when I try to flash.
you can't root 4.4. You are stuck until (hopefully) someone releases a root exploit for 4.4

can you post a screen shot/picture of the error you are getting and also the cmd window where you are entering the fastboot commands?
