Spent a buttload of time trying to find this info on the internets, it seems like every method required root or other warranty-voiding methods, this one (which iv'e stumbled upon on a foreign website) works without any tinkering at all, very easy ...
You're most welcome! Glad to hear this helped! :)
Guess I have my answer now; this method works on other devices and older firmwares awell. :D
A subforum for Moto G 2014 LTE (aka. Moto G 2015) would be most helpful.
Something similar to what you've done with the Gen1 Moto G forum: http://forum.xda-developers.com/moto-g/4g-development
XT1072 here. upgraded from XT1032 GPe :)
I went back and forth between the two on a few kitkat phones (inc. G GPE) with no issues really.
there was an issue with some version of Flipboard which would bootloop your device if on ART, think its solved by now, not sure though.
