First you must make cure with the right firmware according to your device HWID,or your old GCD shows.
If you dont know it use [Only registered and activated users can see links. Click Here To Register...]
Then flash cure by Updater.exe in preboot, format nuvi following this: [Only registered and activated users can see links. Click Here To Register...] -
After formatting ,reflash original firmware in preboot with Updater.exe :Nuvi cant boot with cure firmware, it's made to remove problematic files plugged USB to pc or to format nuvi.
Then run Webupdater.
All the steps are necessary in your case I think, but you havent written what happened before having this problem , so I cant help.
This in very few words, but all is explained better in post n1 (useful links in post n.3 too)

After you loaded Kunix's cure with Updater.exe in preboot mode ,does Windows see your Nuvi if attached USB?
Have you USB Garmin drivers installed?

Probably you would need to erase NV memory ("ergn,41" command in update.txt). If it's corrupted, your device will reboot continuosly even when the CURE firmware patched by GarminCure3 is flashed. Now I'm going to bed, I will write a how-to for you tomorrow if someone doesn't do it sooner. We need another cure for NV clearing, yeah.

Here you are: [Only registered and activated users can see links. Click Here To Register...]
How to use it:
1) Take a clean SD card, copy Garmin folder from the archive to the root of the SD card.
2) Insert the SD card into your Garmin device.
3) Flash RGN file from the archive. (You said you were able to flash firmwares so I don't explain it in detail).
4) Wait 5 minutes.
5) Extract the SD card and post SD:\Garmin\Updater\0943\update.log here (while erasing your UnitID here).
