I emailed Trimble on the off chance they might have a firmware upgrade. They sent me an email which covered some units that rolled over in Feb. 2016 for which they say they have no upgrade.
I sent them all the information on the label stuck to the outside of my TB (one of the group buy set), to see if there's any hope ...
I'm not optimistic, but if you don't ask, you don't get.

That does not appear to be the case. If it did a reset the DAC should have gone to the InitV eeprom setting of 2.800V, but instead mine spiked to 0.308V which is not close to the InitV or the last known DAC values.
My log file shows the unit did a filter-reinit followed two seconds later by phase locking the PPS.
> Or maybe the TBolt reset on rollover and went back to a previously saved DAC value.
