So!

My UHF 5550 started a new problem all of a sudden.
It was in a remote configure and worked fine. Removed it from one vehicle and installed in a new one and now im getting the red flashing light on the screen and i cant TX on any channels.
When i put the programming cable on i dont get any accessory connected tone via the mic input nor on the rear accessory jack. Same when i plug a microphone in no joy. I can read the radio via BT.
Tried a different control head and ribbon cable and no different. Even making it a front mount no change...

Ideas?

Firmware R02.40.11
Codeplug 08.04.04
Bootloader R02.40.10
