@ciprigfh
I think you may have confused the instructions. EITHER you directly use the supplied QuickCure3.rgn (unchanged, just safely renamed appropriately as XXXX01000xxx.rgn - see below) OR you use the device's actual firmware to make the Cure3 RGN. It seems like you're trying to make the Cure3 fw from QuickCure3.rgn. QC3 is ready to use after renaming, "XXXX" being your device's HWID and "xxx" being the current fw version loaded to the device, e.g. 290001000154.rgn. Whether you use QC3 or Q3 the RGN's safe-naming convention is the same. Best try with QuickCure3 first as it usually works, but Cure3 always works to re-enable Mass Storage Mode in compatible devices.

It seems the Fenix 5x plus firmware may not be in traditional Garmin format therefore it's not recognized by GarminCure3.exe for patching of file names. Check if it's encrypted because if so there's no help for that as far as i'm aware.

Have you tried using QuickCure3.rgn? If not and you want to try it, [Only registered and activated users can see links. ]. Rename it to 290001000154.rgn and flash in preboot (at your sole risk of course, i don't know the outcome).

Another way if it's not encrypted firmware is to try the old original method we used before kunix made his cure3 app. Done by using a hex editor to rename IMG to MIG for example in the firmware RGN to make a cure firmware specifically for by-passing loading map image files on boot.

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

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.

@heresy
This reply is not timely sorry, i only just now noticed and read your post. If you still need help to solve you may need to give some more info after trying again as below.

Some thoughts:
Firstly, 1xxx devices don't use NTU (Unicode) maps, they are only offered NT maps by GarminExpress.

Secondly, QuickCure3 usually works with 1xxx devices but not always depending on the problem causing the soft-bricking.

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."

That error message may be only due to the device and Updater.exe losing communication, for instance by the device dropping preboot mode, or due to some corruption in the cure RGN file, but it can also be indicative of a damaged flash region that cannot be written to. I suggest you re-make the cure firmware and try again to flash but this time ensure that the RGN is loaded to Updater.exe with it's GUI visible on your desktop and the radio button next to "USB Device" selected. Ensure your device is fully OFF, not just in standby. Hold the top LH corner of the nuvi's screen and connect the device to the PC watching the window next to "USB Device" for it's details to appear. IMMEDIATELY you see the window populated, press OK on the GUI and keep holding the screen firmly.

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.

Spoiler: image

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

Spoiler: image

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.

Spoiler: image

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

Spoiler: image

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.
