you can do the manual method instead of using rsdlite because rsdlite can be fussy.
download this file and unzip.
moto-fastboot
unzip your6.7.246 fxz file (the one you downloaded from my thread) to the same location as moto-fastboot
I believe your phone is in fastboot already if not press and hold the volume down and power button at the same time on the phone. The fastboot menu will appear. plug your phone into your computer.
navigate in windows to the location you have everything unzipped to. click on the file symbol in the top left corner and when the bar becomes highlighted type cmd and enter if you have win 7. A comand prompt will come up. If not go to start and type cmd and hit enter. when the prompt comes up type cd c:\location of file with moto-fastboot and fxz file unziped
type and hit enter after each step
