Well, we're waiting a lot of time so I'm going to just have you do some stuff manually as this isn't getting us anywhere. Basically it's not finishing the flashing. I'm not sure if you're not going to the next step after the first flash or if there's something wrong. Either way, let's just get this done.
o) Put your phone in AP Fastboot mode and connect to USB
o) Open a command prompt to the SamuriHL_HouseOfBionic folder then type the following commands:
utils\moto-fastboot flash system 246_FXZ\system.img
utils\moto-fastboot flash preinstall 246_FXZ\preinstall.img
utils\moto-fastboot flash boot 987222\boot.img
If those 3 flash commands succeed, shut the phone off, then boot into recovery and apply the update. Done.
