Triumph 1 not communicating after update

I use a T2 as my base and Triumph 1 as my rover. Radio is HPT401BT. I am using Carlson SurvCE on a Carlson mini data collector. Every time I set up I load a Command File in order to allow the Carlson data collector to communicate. Everything was working fine until the beginning of March when I noticed that none of the Glonass satellites were sending data to my set up (very important here in Alaska) so I did a firmware update on both the T2 and the T1. I also cleared NVRAM. Now when I set up I go through the same process: I set up GPS Base, use the GPS Utilities feature to load the command file, then use the GPS Rover utility on Carlson. Since updating Firmware with the Stable version, I cannot get the T1 to communicate. Latency is "N/A". The Modem indicator remains red and the T1 remains Autonomous. Any ideas?

Please update the firmware of your T1 to latest version, not "stable" version. It is my understanding that "stable" version is the original firmware.
