I just picked up this device and flashed the M6 build (cm-11-2014-05-04-SNAPSHOT-M6-jflte.zip) and, during my usual setup routine, I couldn't find the carrier options. Under System settings> Wireless & Networks> More, there was not the usual "Mobile networks" option; did this get moved somewhere (I'm coming from CM10.2.1, where it was present on this device)?
