Default Fake Motorola update signature to install 4.2.2

The purpose of the thread is three-fold:

1) understand why a phone with 4.4 from the factory (not 4.4.2) cannot be downgraded by RSD Lite or motoboot to 4.2.2 with an exception that says "downgraded security" or similar
2) figure out if there is a way to fake whatever is detected during flashing to make it think it is receiving an upgrade and not a downgrade
3) figure out whether it is possible to modify the system
img from the 4.4 or 4.4.2 update and to inject root on a locked bootloader
