Any ideas?

You done something wrong. Follow catymag's advice re USB drivers, different usb cable and another OS also ensure that you keep pressure on top LH corner of the screen consistent and steady or it'll drop preboot. Preboot is only held for ~30 secs in 1xxx devices so have G7ToWin open and ready. Also, read this post and try again following it to ensure you get correct firmware for your HWID: [Only registered and activated users can see links. ] [Post #4].

Also where can I download the correct firmware? I tried to follow the guides on how to download them on Garmin website but can't really find them

Copy and paste the desired coded link from [Only registered and activated users can see links. ] into your browser, for example:

Still when I try to do the update with updater.exe it detects the device but as soon as I click update i get error "the garmin device is not responding"

It's dropped preboot.

One more thing... the device is so stuck on the logo screen that it can't be turned off... pressing power button doesn't do anything So I have opened the device and I disconnect the battery to turn the device off.

That's unnecessary. Hold the power button down to force it off. Many devices need it held for >30 seconds.

I can confirm this. I unbricked a nüvi 765 earlier this week that was stuck on the Garmin splash screen. Had to slide the power button to 'OFF' unusually long to finally get it to power down. The 30 seconds mentioned by Neil are a fair indication as to how long could be required.
