I bricked my Garmin Nuvi 205 now it shows only Garmin logo

It can't be turned off ... only with reset button on bottom can be turned off.
I can't get to preboot mode by holding one of ends of screen.
I have used cure3 to make rgn file and update it to device. Then it got stuck.

Before that I updated by webupdater to latest firmware and had problem with no sound (turn by turn)

PC show Garmin disk drive 1 GB empty
Tried to enter preboot mode but no luck. Logo is still on screen.
Before that I used to enter preboot holding screen on battery sign.

I have Garmin USB drivers installed.
I can't find HWID

No system backup ... only maps

Please help.

Sinisa
