There is no such thing as a 100H, there's the 100P and the 100M, I'm assuming you have a 100P since you are using unity product management.
The OP said NOTHING about NAS so idk where the hell you people are getting trunking from.
As for the OPs issue, it could be numerous things but since the radio is showing up in UPM, I would go ahead and give the 100P the old three finger salute factory reset (PTT, Two front menu buttons on power up). See if that resolves it, if it doesn't, then it could be a bad UDC connector, programming cable or needs FW.
