OK, I just did the advanced option to wipe dalvik, cache, system and data. Then reflashed CM11 - still doesn't get LTE. Also the carrier says Rogers Wireless instead of Fido on the lock screen.
Do I need to change the APNs? After reflashing, there are 4 APNs created including:
Fido FTE = ltemobile.apn
It's weird that it would create a Fido APN yet display "Rogers Wireless" as the service on the lock screen.
