I recently was writing to my XPR 4550 UHF mobile and halfway through the programming the radio froze. I tried turning the radio off and reprogramming it again and now my laptop will not recognize the radio. It says it’s a failure when I look at the Device Manager on my laptop. The radio also has deleted channels from zones and scan lists. Basically it’s moved channels into random zones and scan list. Does anyone know of a way that I can reset this radio from the buttons on the radio? Thanks.
