Issues unlocking Moto E 2nd 4G LTE (XT1527) anyone else can confirm it works?

I'm having issues unlocking the boot loader on the Moto E 2nd 4G LTE (XT1527) can anyone else confirm this phone can be unlocked?

I've gone through all the steps and it tells me this is not a unlockable phone even though I know that there is a CyanogenMod port for
this model.

I'm in the US, is there anything else besides having a supported unlockable phone, that can cause them to flip you the bird when it
comes to unlocking?

I'm going to call their tech support tomorrow, but it would be nice to have a confirmation before I get on the phone with them.
