Creating your theme for Xiaomi Redmi Note 10: from idea to installation

Xiaomi Redmi Note 10 is one of the most popular smartphones in the MIUI line, but even its standard themes can get bored. What if you want to stand out by adding unique icons, fonts or animations? Creating your own theme for the Redmi Note 10 is a non-trivial task, but it is quite possible even without deep knowledge in design. In this guide, we will analyze the entire process from preparing graphic elements to final installation through MIUI Theme Editor.

It's important to understand that custom themes for MIUI have their limitations. For example, some system elements (such as the notification panel or the lock screen) may not be completely reworkable without root rights. However, even with these restrictions, you can change icons, wallpaper, fonts and color schemes. If you're willing to experiment, let's get started!

Before you start, make sure your Redmi Note 10 runs on the current MIUI version (preferably MIUI 12.5+ or MIUI 13/14). Older versions may not support some of Theme Editor's features or have bugs when applying custom themes.

1. What will it take to create a theme?

To develop your own theme for the Redmi Note 10, you’ll need not only creativity, but also a range of tools.

• 📱 Xiaomi Redmi Note 10 (or any other on MIUI) with unlocked bootloader (optional, but expands the capabilities).
• 💻 Computer with installed programs: Adobe Photoshop (or free analogues like GIMP/Krita), Android Studio (for working with APK), MIUI Theme Editor (official software from Xiaomi).
• 📁 Theme templates for MIUI (can be downloaded from the XDA Developers or MIUI Themes forums).
• 🔧 Knowledge of the basics of working with graphic editors and the.mtz file structure (theme format for MIUI).

If you're new to design, don't be afraid: many of the themes (like icons or wallpaper) can be downloaded and customized to suit your needs, and the key is to understand how these elements interact in the final theme.

⚠️ Warning: Installing custom themes from unverified sources may cause malfunctions MIUI. Always check.mtz files for viruses and compatibility with your firmware version.

Also note that deep customization (e.g., changing system animations) may require unlocking the bootloader and obtaining root rights. This voids the warranty and increases the risk of "bricking" the device. If you are not ready for such experiments, limit yourself to editing icons, wallpaper and fonts.

Preparation of graphic elements

Any MIUI theme consists of a set of graphic files packaged in the.mtz archive.

• 🎨 Application icons (must be in.png format, size 192×192 px or 256×256 px for high resolution).
• 🖼️ Wallpaper (for the home screen and lock screen, a resolution of at least 2340×1080 px for the Redmi Note 10).
• 🔤 Fonts (.ttf or.otf files supporting Cyrillic if needed).
• 🎛️ Color schemes (colors for status bar, notification panels, buttons, etc.)
• 📱 Interface elements (background for folders, switch style, sliders, etc.)

For convenience, we recommend downloading the finished theme from the official store MIUI Themes, unpacking it (the.mtz file is a regular ZIP- archive, rename the extension) and using it as the basis.

💡

Use Flaticon to search for free PNG icons. Be sure to provide authorship if the license requires it.

When creating icons, stick to the MIUI style: minimalism, flat design, a single color palette. If you want the theme to look professional, avoid too bright or contrasting combinations. For wallpaper, it is better to use abstract textures or photos with a blurred background - they will not distract from the icons.

3.Working with MIUI Theme Editor

MIUI Theme Editor is the official Xiaomi app that allows you to create and edit themes directly on your smartphone, but its functionality is limited compared to manual file editing.

1. Download MIUI Theme Editor from Google Play or MIUI App Store.
2. Open the app and select Create a new theme.
3. Download the prepared graphic elements (icons, wallpaper, etc.) through the built-in file manager.
4. Set up the color scheme and fonts in the appropriate sections.
5. Preview the topic with the Preview button.
6. Save the theme in.mtz format.

If you need more features (like changing animations or system sounds), you'll have to edit the files manually.

1. Unpack any.mtz file (rename it.zip and retrieve the contents).
2. Edit the files you want (for example, replace the icons in the icon folder or wallpaper).
3. Pack it all back into the ZIP- archive and rename it.mtz.

⚠️ Warning: With manual editing,.mtz is easy to break the file structure. Always back up the original theme and check for compatibility with your version MIUI.

The icons are the correct size (192×192 or 256×256 px)

Wallpaper corresponds to the screen resolution (2340×1080 px)

All files are called Latin without spaces

4. Install theme on Redmi Note 10

When the theme is ready, you just have to upload it to your smartphone and apply it.

Method 1: MIUI Theme Editor (without root rights)

1. Transfer the.mtz file to your phone’s memory (for example, to the Downloads folder).
2. Open MIUI Theme Editor, click Import Theme and select your file.
3. After import, click Apply – the theme will be set as a system.

Method 2: Through the file manager (requires a root or unlocked bootloader)

If the first method didn’t work (for example, due to MIUI limitations), try:

1. Copy the.mtz file into /sdcard/MIUI/theme/ (create it if it doesn’t exist).
2. Go to Settings → Themes and select your theme in the My Themes section.
3. If the theme doesn’t show up, reboot the phone.

Important: Some versions of the MIUI 13+ may require you to disable the signature verification of the themes via the ADB- command: adb shell settings put global miui_theme_manager_check_signature 0. This will temporarily disable restrictions, but may affect security.

5. Solving common problems

When creating and installing custom themes, Redmi Note 10 users often encounter common bugs, and here’s how to avoid or fix them:

• 🚫 Theme not installed: Check that the file has a.mtz extension (not.zip) and make sure that the MIUI version supports custom themes (some regional firmware has this feature disabled).
• 🔄 Theme doesn't apply fully: You may have missed some files in the archive (e.g., you haven't replaced icons for all system applications). Compare the structure of your theme to the original one.
• 🛑 The smartphone reboots after applying the theme: This is a sign of conflict with system files. Delete the theme through Settings → Themes → My themes and check it on another device.
• 🎨 Colors are not displayed correctly: There may be errors in the color codes in the colors.xml file (if you edited it manually). Use the verified HEX- values.

If the topic is not stable, try:

1. Clear the cache of the application Themes in Settings → Applications.
2. Set the theme through the Recovery (if you have custom Recovery like TWRP).
3. Reverse changes through MIUI backup.

6.Publishing and disseminating your topic

If you’re happy with the result and want to share your theme with other Xiaomi users, there are a few ways to do it:

• 🌍 Official Store MIUI Themes: To publish a topic here, you need to go through moderation. Upload your.mtz file to themes.mi.com and fill out the developer questionnaire. Usually moderation takes 3 to 7 days.
• 🤝 Forums and communities: Popular platforms — XDA Developers, 4PDA, MIUI Russia Forum. You can upload the topic for free and get feedback from users.
• 💰 Marketplace Sales: Some themes are in demand and can be sold on platforms like ThemeForest or Creative Market. Make sure all the resources used (icons, fonts) are commercially licensed.

Before publication:

1. Test the theme on multiple devices (preferably on different versions of MIUI).
2. Create screenshots of all screens (main screen, application menu, lock screen, etc.).
3. Write a detailed description indicating compatible devices and firmware versions.

⚠️ Warning: If you use copyrighted elements (such as brand or character logos) in a topic, it may be blocked on sites.

💡

Before posting, check the topic for bug-free and compatibility with the latest versions of MIUI, which will increase its rating and reduce the number of negative reviews.

7. Alternative methods of customization

If creating a theme from scratch seems too difficult, consider alternative customization options for the Redmi Note 10:

• 🎭 Launchers: Install a third-party launcher like Nova Launcher, Hyperion Launcher or Poco Launcher, which lets you change icons, animations, and even gestures without creating a full-fledged theme.
• 🖌️ Magisk modules: With modules like MIUI Mix or MIUI Mods, you can change system fonts, download animations, and even the notification panel interface. It requires root rights.
• 🔧 ADB- Commands: Some interface elements (e.g., transparency of the navigation bar or status bar color) can be changed via ADB. For example: adb shell settings put global window_light_navigation_bar 1 This command includes a light navigation bar.
• 📲 Design applications: Hex Installer, Substratum (for Android 8-9) or Andromeda (for Android 10+) allow you to use theme overlays without completely replacing system files.

If your goal is simply to refresh the look of your smartphone, these methods may be easier and safer than creating a theme from scratch, but they won’t give you as much control over the interface as a custom.mtz theme.
