Note: If you are rooted, you will need to have the Xposed Framework.
Step 1: Download the APK
Since Z Launcher isn’t widely available, simply download the zLauncher.apk(mirror link). After it’s downloaded, make sure you have Unknown Sources enabled, then install it like any other app.
Step 2: Download the RootCloak Module
To bypass the root check of Z Launcher, you will first need to download the Xposed module RootCloak.
Don’t forget to Activate and Reboot afterward.
Step 3: Add Z Launcher to RootCloak
Adding Z Launcher to the list of RootCloak enabled apps is as easy as opening it, tapping the + icon up top, and selecting Z Launcher.
