Install MTZ Themes on HyperOS

Hey there! Wondering how to install MTZ themes on your Xiaomi phone? Today, I’ll show you a simple way to do it on both HyperOS and MIUI devices.

After the MIUI 11 update, the Mi theme store stopped supporting MTZ themes. But, many designers share beta versions that you can still use. I’ll show you a way to install any MTZ theme on your Xiaomi, Redmi, or POCO devices, no matter the MIUI or HyperOS version.

What are MTZ Themes?

MTZ themes are files for custom themes and fonts on Xiaomi devices, working only with Xiaomi operating systems. They let you personalize your device with unique looks and apply HyperOS themes without waiting for official updates.

Part 4: Remove Theme Manager Folders

  • Download and open Solid File Explorer or any file manager from the Play Store that allows access to your device’s internal Android folders.
  • In the file explorer, follow this path: Internal Memory > Android > Data. Look for folders named “Theme Manager.”

Conclusion

This process can be quite complex and time-consuming due to the various settings adjustments required. By following these steps, you can successfully install new themes directly from designers and experiment with custom fonts and themes not available in the Theme store.

However, be aware of potential challenges:

  1. With the Android 13 update, many smartphones restrict access to system folders. You’ll need a best file manager that allows access to all files.
  2. There’s a risk of making mistakes while renaming folders, so be extra careful.
  3. After recent HyperOS updates, some MIUI themes may not be compatible with the new version, and popular themes might be removed from the server, leading to errors like “Server error” or “Unfortunately, our server is down at the moment.” In such cases, contact the official theme developer for a newer version.
