Can you give more details on the "Any time you try to enable LTE for a 2nd time, you get a port connection error" problem?
Is this a red message in the LMI about port 1049? (That message may be normal, but clears itself after a few seconds.)
When you say "enable LTE for a 2nd time", what is the sequence of events?
Also, we have a resolution for the problem of some phones not seeing the network. Please contact me privately to arrange an update for your LTE software.
