About Fastboot...

If I do:
Code: 
reboot bootloader

I see Android in Windows Device Manager so it seems Driver is missing...

Will try this:
developer.android.com

Get the Google USB Driver | Android Developers

The Google USB Driver is required for Windows if you want to perform adb debugging with Google devices.
developer.android.com developer.android.com

Edit 1.

Hmmm... need some time or maybe I have to modify self...

Code: 
USB\VID_18D1&PID_D00D&REV_0100

USB\VID_18D1&PID_D00D


Other more important problem...

For now only via ADB WiFi...

Hmmm.

To prevent Software Update I hope this work...
Code:

My mistake I ever thought FOTA Delta is in /cache/fota...

But seems wrong.

Both, Standalone method from Watch... and method via Phone and Wear app copies to:
Code: 
/data/fota/update.zip

Short tried to deinstall the "FOTA Manager"...

Maybe """soon""" I have other solution to prevent my old EVA8 to update...

    I want to make a small contribution to the thread in question, I have a gw4 ldu which did not allow any device configuration. I downloaded the SM-R890 EVA8 file and unzipped it with 7zip and then retransformed in tar format again with 7zip. I then connected the gw4 with netodin and uploaded the file to the device. Finished the job everything works wonders, it also received the latest update released by samsung. Tanks to Adfree for his hard job
