Thread: IMPORTANT! If you want HELP in case of a bricked Garmin device, please follow this

BMW Motorrad Navigator IV and zumo 660 are identical internal hardware (they have the same HWID of 0924). Your info implies that the Nav IV has a hardware rather than a software problem - i.e. Symptoms of unable to copy files to computer in Mass Storage Mode and its GarminDevice.xml file having no content, the latter means the device is incapable of updating itself on boot cycle (that's likely why it was so slow to start-up previously).

What exactly do you mean by "Now it is not working any more"? If it appears completely dead but you are sure the battery has charge, take it into a very dark room and hold the power button to see if the screen glows slightly.

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.

Butters,
No words to express my happiness, and my thank you to see the Nav IV working perfectly!
Sorry for my mistakes, it was a long time that I didn't repair a Zumo.
I have to thanks all the people that keep this site ON, helping GPS Users and doing the job that the brands should do, but they don't.
Thank you very much
