[Moto X General] yeticomes:
Doesn't work for me - I put all DE Retail Files into the platform-tools Folder and copied both Roger Files there, too.

Than I flashed these files with the following commands but after rebooting the Moto X it was still/again on the canadian Rogers 4.4.2, as you can see in the Screenshot.

Where did I make a mistake?!

Here the Terminal commands:

sudo fastboot oem fb_mode_set
sudo mfastboot flash partition gpt.bin
sudo mfastboot flash motoboot motoboot.img
sudo mfastboot flash logo logo.bin
sudo mfastboot flash boot boot.img
sudo mfastboot flash recovery recovery.img
sudo mfastboot flash system system.img
sudo mfastboot flash modem NON-HLOS.bin
sudo fastboot erase modemst1
sudo fastboot erase modemst2
sudo mfastboot flash fsg fsg.mbn
sudo fastboot erase cache
sudo fastboot erase userdata
sudo fastboot erase customize
sudo fastboot erase clogo
sudo fastboot oem fb_mode_clear

Here the results I got in the Terminal:
