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

How to unbrick a nüvi - step by step guide

Readed and tried, used nuvi13xxand14xxseries_GCDFile__630.gcd

I get error message "The GARMIN device is unable to program the requested memory region.
This could be due to an incompatibility between this application and the GARMIN device.
If this error continues to occur, please contact GARMIN Technical Support."

9) Can you reach preboot mode? If no ,have you followed this? Garmin devices preboot mode

Yes, holding upper left corner before powering on.

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

Thanks for the input, Butters!

I think it messed it up with the NTU maps, but i had no idea...

Here's the step by step:

1. I improvised a "hack" to enter preboot - just a simple spring clamp and a rubber, it gets the job done so both my hands are free work. The USB cable is plugged in my PC and the micro-USB part I plug after setting the updater.

2. I prepare the .gcd in "GarminCure3 v0.1 by kunix" using "nuvi13xxand14xxseries_GCDFile__630.gcd". I launch the updater and set the USB connection option. The cure gets discovered and i proceed with the steps

3. Once I see it discovered i hit Enter and dash for the "Yes" menu with the mouse that is prompted (it says the current software is the same, and so on...) .Here's why i use the hack from 1. to utilize both hands. It starts doing it's thing updating, gets to the point of "Erasing" and here i hit the brick wall - every time i get the "unable to program in this memory region" error.

4. I also got a random error about the updater, no idea if it will be of any use

I tried like 10 times restarting everything, clearing the temp folder, making new cure, setting up the updater, prebooting, connecting and every time it's the same error message regarding the "memory region".

Some thoughts:
Am i using outdated .gcd for the cure? If so where can i get most recent one, or one that is more reliable?
Am i using an outdated version for the GarminCure? This one says v0.1.
Am i using a wrong data cable, i tried like 3 different ones and all of them discover the nuvi in preboot but i get to the error about "memory region" and that's it.
