So why the baffling decision not to provide further support on the 2014 Verizon and AT&T models, while letting owners of the "Pure Edition" upgrade? Many suspect it's a carrier issue, though Motorola, AT&T and Verizon aren't saying. If you're particularly keen to get the latest Android version, bear in mind that unlocking your Moto X, even with the official codes, will void your warranty and wipe the device. And once that's done, there are still numerous steps to get a new ROM installed. If that doesn't dissuade you, you can hit Motorola's "unlock your bootloader" page to give it a go.
