这是一个可怕的错误
Installation failed with message Failed to finalize session : INSTALL_FAILED_USER_RESTRICTED: Install canceled by user.
It is possible that this issue is resolved by uninstalling an existing version of the `apk` if it is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?

MIUI 8.5出现设备暂时受限错误。要解决这个错误，你需要关闭WIFI，打开移动数据，然后在“设置”中的“开发人员选项”下启用“通过USB安装”选项。它会对你有用的。
If above answer didn't work for you as it didn't work for me on my Xiaomi Mi5.I tried to figure out the Core reason behind it and solve it. In MIUI, in order to change "Install via USB" option, you must be connected to the internet and signed in your Mi account. Due to some reason, requests from out of the China servers are getting rejected, so I connected to one open China VPN and tried again to enable 'Install via USB' and I got success. For detailed solution and VPN details, see this useful Youtube video: https://youtu.be/MeKUJlD-Ke4
