v2.3.x Special Update Instructions Notice: Please install v2.3.0.1 as USER app.
Important: New v2.3.x V4A has new package name, therefore follow this installation steps carefully.
1. Open old v2.2.x V4A, save the effect profile.
2. Uninstall old v2.2.x V4A. Complete uninstall, including both driver and app. Reboot.
3. Install new v2.3.x V4A, choose Yes to "Install/Update". (V4A auto detects and installs correct driver.)
4. Reboot, open new v2.3.x V4A and load effect profile saved in step 1. Note: Xiaomi M1 not working for some users. But Xiaomi M2S with MIUI v5 is fully supported.
If driver installation fails,
1. Install busybox from Play Store, reboot and try again.
2. If persist, for non-MIUI roms, users can install SuperSU (latest version), reboot and try again. Since MIUI roms have SU built-in, its not recommended to install other SU apps.
