I have a Zuk Edge with ZUI 2.5.500 ST and Android 7.0 English version.

The System Update menu says: "Your system has been root, we are unable to provide the latest version of the system."

I would like to upgrade the ZUI to the latest fixed version and the android (8, 8.1, 9 I dont know which is better for thie phone) if it works.

The question is, how can I do that, what steps I have to do and where can I download the necessary programs for it?

Thank you for the help!
