Usual stuff, drag it onto Updater.exe, connect in preboot mode and hope it flashes.

The flash was successful, but it made no difference to the symptoms of the zumo.

Well... not completely true. There is a difference in that the unit does not switch off anymore after 3 seconds when on battery power. It stays on now (still frozen on the Garmin splash screen) until switched off manually by pressing and holding the power button for more than 5 seconds.

I don't fully understand. There is a rgn14 in the unit which I can dump as described. What exactly do I compare it with?


Edit 1:
I notice that since the above action, the zumo is not recognised anymore by the PC, WebUpdater or Garmin Express.

Edit 2:
Had to flash CURE FW into the unit via GarminCure3 and Updater.exe to get it recognised again by PC etc.
