Thank you,

Unfortunately, I'm not seeing the same results on my end, it's possible the radio may already be bricked.
Here's what I attempted:
Installed the 3.1.20.006 updater
Connected the radio via the appropriate cable
Powered on the radio while holding the PTT and TK buttons (device successfully entered DL mode)
Launched the software and confirmed it was set to Auto Mode
Upon attempting the upgrade, received the error: "Upgrade Failed! Query radio user define data error!"
At this point, it seems likely that the unit may be beyond recovery. We may need to proceed with an RMA.
Unfortunate, but it is what it is.
