I last used my Edge 840 and successfully sync'd the device on Sunday 12th Jan and then selected to Power Off the device (hold down power and select Power Off). I have done this many times before without issue.
I then turned it on Wed 15th Jan and the device immediately went into a boot loop.
Device is running load 25.25 (This was updated previously)
I was able to eventually reset the device (through much frustration!!) and get it up and running again, though no base map.
I then connected to the latest Garmin Express ( I had removed/uninstalled existing version and cleared all Garmin files/folder from \AppData\Local\Garmin) and selected my required Map (Routable Africa 2024.10). This then installed and I rebooted the device.
When it started up , The splash screen displayed a message "GCD update failed" and the device restarts.
It then displays the splash screen shows "loading courses, workouts and locations, then restarts and goes into a loop. This is where I'm stuck.
I can boot it into MTP mode, though I cannot get it to start normally.
Any suggestions ? Is there something in the Debug\EventLogs etc that can be used to pin point the issue?
