Please detail how it was seen by PC. For example: By File Explorer (Mass Storage Mode), or in Device Manager (preboot mode), or by one of Garmin's programs like MapSource/BaseCamp, or ?

Are you sure pre-boot isn't available? Most devices which boot only to the logo still have preboot. If it was stuck on logo screen then it's easier to find and maintain preboot but devices which reach the logo then either turn off or attempt to re-boot are more difficult.9-no
The vast majority of devices which will turn on and show the logo even briefly can be recovered with persistence.

Hi Everyone ! I'm totally new here.. but begging for help, i feel hopeless to throw away such an expensive device
...
It's my first post, out of desperation :p!
BMW NAVIGATOR V , Firmware version 3.5 , HWID 1451 .
2) Why and how the device got bricked.
Laptop battery died during a Garmin Express update...
3) Symptoms: what's wrong in your device?
Stuck on Loarding screen (but not even the "loading maps, just the BMW motorrad logo/garmin, with nothing else below it)
Not recognized by PC
4) Does your pc sees your device ?
NO (Only in preboot in Device MNGR)
5) List all the procedures you already tried to unbrick it and their results and errors messages obtained.
Garmincure3 procedure (according to the tutorial) - Flashing Complete the cure(based on 3.5 Firmware from garmin) without any error, but the GPS doesn't go in Mass Storage Mode
Quickcure3 - same
Usb isn't flakky/badly connecting. it's really gps related only (It detect the pre boot fine)
6) Do you have Garmin USB Drivers installed ? Garmin: USB Drivers Updates & Downloads
Yes, and it's working properly on another unit.
8) Write down if you already read or tried GarminCure3 tool - the new way to create cure firmwares for Garmin devices
How to unbrick a nüvi - step by step guide
Yes. as mentionned before
9) Can you reach preboot mode? If no ,have you followed this? Garmin devices preboot mode
I Can reach preboot mode.
10) Probably no , but do you have NV backup?
No, but i've got another device,same model on hands...Last edited by Nerox; 30th July 2020 at 10:56 PM.
