before you reflash as it was said earlier boot into the stock recovery.
pull your battery out, put it back in, hold the home button down, power up, you should see the boot logo (red Moto logo) and then the stock recovery screen. in the new stock recovery you have to press both volume buttons to have the menu pop up, use the volume buttons to scroll to data wipe/factory restore option, click the power button to select the wipe. it takes a few minutes for the wipe, after that reboot.
if that doesnt work then you will need to sbf again.
