Firstly I checked the IMEI with *#06# and its not zero.
But I made the update with Win10 and it skiped the steps 9-11…
After downoad the message with grean circle appeared. After that the watch started up properly, I set the time etc. works fine except the call with SIM card (it can get the phone book from the SIM but cannot register for the connection)
Do you think that that update was corrupted because of win 10?
If nothing else works, can I get the older firmware? Unfortunately I did not backup.
