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

1) Bricked device MODEL, Firmware version, HWID.
GARMIN NUVI 1340, Software version 6.30, HWID 972

2) Why and how the device got bricked.

I tried to install some maps via BaseCamp v4.3.4 witch prompted me to update and i let it, i got a message that a substantial amount of data will be installed.
I think the map was this "Garmin City Navigator Europe NTU 2020.20 UN FID 8219"
Near the end installing something happened, witch said that the installation was completed but "not successful"
The device sat there some time with the PC connected logo and after that it went into "GARMIN LOGO" loop

3) Symptoms: what's wrong in your device?
When power-on, it shows Garmin logo and restarts itself, and again the same.

4) Does your pc sees your device?
As normal no, only when keeping finger on the top left screen to access preboot mode.

5) List all the procedures you already tried to unbrick it and their results and errors messages obtained.

Tried QuickCure3 and it gives me "Update successful" but my PC still can't recognize the device after this operation.


6) Do you have Garmin USB Drivers installed?

Yes, Garmin USB Drivers 2.3.1.0

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