This thread may be out of date, but to those helpless souls who've wandered back to the last page - HOPE DOES EXIST!
I have been rooting my phone and breaking things and getting new ones and rerooting for years now, and moto has gotten pretty tricky with their bootloaders, and what we the consumers need to keep in mind is that our phones arent necessarily supposed to do this.
That being said, my new rule of thumb (after FINALLY gaining root this time) is to always treat your phone like youve never rooted it before - computer too.
This means - uninstall and reinstall moto drivers
delete and redownload and unzip the currently working root tool (@ this time its motofail or zergrush {doomlord} that can both be found on xda or through a google search)
use a usb port on the back of your computer
restart phone and computer directly before trying to root
I was getting failure after failure while i did all these things again and again, and my problem was this -
INSTALL YOUR ROOT TOOL TO A FOLDER PLACED ON THE DESKTOP
I dont know why, but when i had it placed on or two subfolders down it seemed to fail every time, and as a last resort i redownloaded and unzipped the file into a different directory (unwittingly) and WALA! worked perfectly.
I was on stock .906:icon_eek:
