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
