Thread: IMPORTANT! If you want HELP in case of a bricked Garmin device, please follow this

newbie, here with a failed firmware upload.
1) Bricked device: Montana 610 , Firmware version:failed to update 3.50, HWID - 3921841949.

2) used basecamp to update firmware. After restarting garmin did the "validating update" screen, gets to somewhere between 22% and 31% and screen fades off

3) Symptoms: wont boot, as above crashes during validating update

4) Does your pc sees your device: very briefly with basecamp not GE, and only if i hold power button depressed

5) List all the procedures you already tried to unbrick it :as above, holding power button it will connect via USB momentarily. But by the time I have used Basecamp to find device and search for updates the screen has reverted to "validating update" and faded off.

6) Do you have Garmin USB Drivers installed ? yep

7) If you don't know HWID get it by Use program G7ToWin to retrieve your HWID - trying that now

8) Write down if you already read or tried GarminCure3 tool - giving this a go once i figure out HWID

9) Can you reach preboot mode? sounds like i did accidentally.

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