Meizu's mobile phone information is not marked. What should I do?

Meizu mobile phone information has no icon. The solution is as follows:

① Download Xiaomi Desktop and install it. If you can't download it, just send it to your mobile phone with another mobile phone Bluetooth, and then install and allow all permissions.

② Directly brush the machine to solve the problem.

Note: It is invalid to restore factory settings and enter recovery mode to clear data. I tried this.
