Is the ROM file renamed to CP960.rom, or it was left with the original file name?

I'd try with an older rom instead of a more recent one. Take version 73.80.0.25 from here, export the ROM file from the ZIP and rename the file to CP960.rom.

Thank you for the reply,

Older version seems good idea, however the link is not working (Page error 404 and Chinese language from Yealink site!.

"update failed - 1" message (ONLY) appear if I intentionally made wrong rename to the 3 files names or if I didn't copy the ROM file or if i plugged the USB Flash next to the left side Mic (for testing purposes) to my understanding this mean the recovery process is reading the data and can tell if its wrong !

now I am not getting error message of any kind because the 3 file renamed, copied to the usb flash drive as it should! so ; it start the recovery process and then in less than 15s of reading the usb the screen becomes blank without any errors!

Yes, the ROM file renamed to CP960.rom and the other 2 files.

So, recovery seems working but maybe I should try older ROM! as you advised.
    this error message only appears if the files is not correctly named or missing ROM file, or flash drive plugged into the mic side..
