PnP resets Snom Phones

[brandywinetech.com]

I am running windows system 3..0.1.3017.exe snom 7.1.35 phones with Plug and play ,

 

after the phone boots , I set the U.S. date format (mm/dd): on off edit to ON ,

 

 

after every reboot it resets to OFF ,.

 

I RESET the phone to factory 5 times ,

deleted the Generated and cleared the TFTP directory ,

 

I can't see what is doing this ,

Report the MAC to snom. Maybe there is something specific with that MAC address.
