There's only some very slight hope of reviving it by software means in that case as that's another indication of a hardware failure. It's proper behavior with Cure fw loaded is to stall on the Garmin logo and stay on.

Have no files inside.
Yes, understandable because you formatted it previously.
Did you use the exact settings for the reformatting as recommended [Only registered and activated users can see links. ]?

The GPS should create a Garmindevice.xml by itself, but didin't. So I can't use Garmin Express to replace the files.
It can only create the XML file when it boots. If it can't fully start, it can't write/rewrite the XML.

The GPS is connecting to the computer.
Good that you still can access MSM.
Does it allow you to write to it? Try creating a root folder named GARMIN.

It still flashed with the cure.
Completely expected that it CANNOT boot. The following is written prominently in kunix's instructions: "Please note that the CURE firmware cannot boot the device, it can only allow the device to enter Mass Storage Mode and connect to PC".
Once faulty files are removed or a reformatting done, ORIGINAL firmware must be written back using Updater.exe in preboot mode. Then it should rewrite the GarminDevice.xml in the created Garmin folder.

I used zumo660_GCDFile__510.gcd
That's the latest available version. Ensure when you create the original fw RGN file from the GCD that you name it as 092401000510.rgn only. But only flash original fw if you can create the GARMIN folder first.
