    That's not your device's HWID, it's the UID (Unit ID). You should edit your post to remove it as it's not something you should disclose publicly.

    2) I disabled the UK Openstreetmap and enabled Worldwide AutoRoute DEM. Switched off and now it will not restart.
    "Worldwide AutoRoute DEM" is an automotive device basemap. I don't think it's an OEM map for eTrex. As it seems from your answer to "5" that you still have Mass Storage Mode available you might solve your problem by simply removing that map.

    Good afternoon, hope you can help me and avoid buying a new unit...

    1) Bricked device GARMIN DRIVE 61 LMT-S , Firmware version 6.00 , ID 3963XXXXXX

    2) Why and how the device got bricked.
    After leaving the car for a service for a couple of weeks (I noticed the car battery had been disconnected as the dashboard clock was reset). I have the GPS permanently mounted in the car.

    3) Symptoms: what's wrong in your device?
    When connected to external power the GARMIN logo appears during 4-5 seconds, the unit turns off, reboots and the same process again and again.... If only with battery, after pressing the power button the logo appears during 4-5 seconds and the unit turns off.

    4) Does your pc sees your device ?
    No, except sometimes if I search device with Webupdater. Explained below.

    5) List all the procedures you already tried to unbrick it and their results and errors messages obtained.
    Tried to hold power button pressed for a minute or so.
    Tried to connect to Garmin Express with no luck
    Tried to force a reset by pressing power button + screen right lower corner. It appears the word System scrolling downwars above the logo and after a few seconds it gets "frozen". Sometimes the word Loading appears, but then the unit turns off.
    Tried to connect to Webupdater and sometimes detects the unit if i search for device just when the powering on with the previous method and the word System is scrolling. If detects the unit and "allows" to reload the same version of the software but it gets stucked (I guess that it has only communication with the device for a very brief time).


    6) Do you have Garmin USB Drivers installed ? Garmin: USB Drivers Updates & Downloads
    Yes

    7) If you don't know HWID get it by Use program G7ToWin to retrieve your HWID
    It does not detect the unit.

    8) Write down if you already read or tried GarminCure3 tool - the new way to create cure firmwares for Garmin devices How to unbrick a nüvi - step by step guide
    Yes, but Updater does not detect the unit.


    9) Can you reach preboot mode? If no ,have you followed this? Garmin devices preboot mode
    Yes, with no luck as explained above.


    10) Probably no , but do you have NV backup?
    No

    That's indicating it's attained preboot mode. Updater.exe should detect it but you must be very quick to load Cure fw because these modern devices retain preboot only for a matter of seconds. Once it exits preboot mode it becomes 'bricked' again. Try this:
    1. Load Cure fw (either full GarminCure3 or QuickCure3) to Updater.exe, select the radio button next to "USB Device" and leave the GUI visible on your desktop.
    2. Plug a USB cable into a rear port of the PC. With the device fully OFF, hold the screen and power it on by plugging the miniUSB plug into the device.
    3. Immediately you see the device detail populate the window to the right of "USB Device" click "OK" on Updater or hit the Enter key on your keyboard. Don't hesitate or it will drop preboot. Don't release the screen until Updater finishes.
    4. If Updater completes and reports success then don't disconnect from PC, the device should become visible as a Mass Storage device allowing you to properly format it. Try to get a backup of existing files first however.

    Let's know how you go.
