TTActivator detects my device, it founds some installed safety cams, updating meta went well but when patching I've got error that my navcore is not supported, then I have realized that I have to install new navcore. And I did downloaded 12.075.3065980.74 for my 820 from here:

The installation process went well, the TT showed messages that it is updating and later that updating is done and that I can disconnect my device. But after the update my navcore version was stil same "12.071.1370596.74". I have tried to install it again, turn TT on/off. I have even tried to install 12.075.3065980.84 version, even if it was not recommended but I didn't have any success updating navcore. MyDrive was turned off all the time.

Could you help me what to do? Should I reset radio or do something else?

Thank you very much.
