Came across a bunch of KNG-CMD and KNG2-CMD portables getting ready for deployments this fire season. Symptoms are the radio appearing to be completely dead - turn the knob and no signs of life. Verified fresh batteries in other radios. Conventional wisdom would suggest a hardware failure, and we were ready to send the radios in for repair.

The "fix" - put the radio in firmware flashing mode (connect programming cable and hold PTT until flashing blue light) and use Lightning Light to load 5.5.0r (latest release, also CALFIRE approved should that matter). Radio starts right up and works like a charm now. Hopefully saves some folks the headache should you end up with a stack of these on your desk.

Is BK aware of this? Usually they are pretty good about not letting this happen.

This has been going on for awhile. The factory says that is the first thing to try before sending it in. Appears to be a random FW issue, easily fixed. I haven't figured out what the customer was doing beforehand. Mobile chargers, possibly?
