I have the same problem as you. I backed it up with the activation backup tool, but it was restored when I reinstalled it. At first, it was activated. Later, two drivers were installed, and the prompt was not activated when restarting. Later, I also activated the phone again and entered the last nine groups of numbers, which was useless. I just called again. This may be because the state of the computer must be exactly the same as when it was last activated. . . Call again.
