Preparation of tools and workspace
Before you start drawing icons or choosing colors, you need to prepare a software base. The main tool for work will be the official MIUI Theme Editor application or its alternatives for Android, such as MTZ Editor. Without specialized software, editing the system archives of the theme is impossible, since they have a specific compression structure.
You will need to install a set of graphics editors on your computer or smartphone. To work with raster graphics (icons, wallpaper, previews), Photoshop or free GIMP are perfect. If you plan to work directly on your phone, pay attention to PicsArt or Canva, although the functionality of the PC versions is much wider.
Remember to back up a standard theme or any other theme you like to use as a basis, so you don't build a project from scratch, but modify the finished, working elements. Copy a standard theme file (usually with the.mtz or.miui extension) into a separate editing folder.
- 📱 Thematic editing annex (MTZ Editor or analog).
- 💻 Graphic editor for high quality image processing.
- 📂 File Manager with access to hidden system folders.
- 💾 Backup copy of the original theme for modification.

Theme Archive Structure and Key Files

The description.xml file, which contains metadata of the topic: title, author, version and description, deserves special attention. An error in the syntax of this file can lead to the fact that the topic simply does not install.
Sound is also part of the theme: ringtones, notifications and alarm files are usually in the audio or sounds folder. It is important to respect the formatting of audio files, usually MP3 or OGG, and their bitrate, so as not to overload RAM when playing.

Development of visual style and icons
The most time-consuming step is creating or editing icons. For the Xiaomi Redmi 8 with its screen resolution, it is important to use high-quality images to avoid pixelation. The standard icon size in MIUI is often 192x192 pixels, but it is better to focus on the source of the basic theme you choose.
Start by creating a single style. Choose a color scheme that will repeat across all interface elements. If you're doing a dark theme, make sure the contrast of the icons is sufficient for comfortable use in bright light. Use vector graphics where possible so that zooming doesn't affect clarity.
When replacing icons, it's important to keep the shape uniform. If the system uses rounded squares, your custom icons should fit into that circuit. Some theme editors allow you to automatically use the mask, but manual fine-tuning often gives you the best result.
☑️ Checking icons before assembly
- 🎨 Use a single color palette for all elements.
- 📐 Observe the grid and sizes of the original icons MIUI.
- 🖼️ Keep the graphics in format PNG-24 support transparency.
- 👁️ Check the readability of icons on different types of wallpaper.
Setting up the lock screen and Always on Display
The lock screen is the first thing that the user sees, and on Redmi 8 it can be as informative as possible. Editing this section requires care, since it involves not only pictures, but also the logic of displaying time, date and notifications.
To change the look of the watch and date, you need to edit the corresponding images in the lockscreen folder. XML is often used to describe the positions of the elements. Be careful: misaligned coordinates can lead to time overshadowing the camera or speaker.
The feature is Always on Display (AOD) Redmi 8 is also customizable, so you can create a static image or a simple animation that will be displayed on the screen off. AMOLED-screens (although in Redmi 8) IPS, Principle of saving is important) can consume more quickly charge, if not optimized.
⚠️ Warning: When editing lock screen files, always check to see if important system buttons such as Unlock or Emergency Call are overriding new elements".
💡
Use translucent PNGs for the interface elements on the lock screen so that they look harmoniously on any wallpaper installed by the user.
Build, compile and install theme
Once all the graphics are replaced and the sound files are matched, the build phase begins. If you've been working on a PC, you need to pack all the files into a ZIP archive, keeping the folder structure in mind, and then rename the extension to.mtz. On a smartphone, this process is taken over by the app rector.
In MIUI Theme Editor, select the option "Collect theme" or "Compile". The program will check the integrity of the files and create a ready-made installation package. During the compilation, a theme.info file can be generated that contains the theme hash sum.
To install a theme on Xiaomi Redmi 8 without being tied to a developer account, it is often necessary to rename the file.mtz to.zip, install themes through the menu -> Profile -> Import, and then rename or forcefully apply it back. Some versions of MIUI run a direct file launch.mtz.
- 📦 Make sure all files are in the root of the archive or the correct subfolders.
- 🔒 Check the file. description.xml syntax errors.
- 📲 Copy the finished file.mtz into the device memory.
- ▶️ Start the installation through the standard application "Themes".
Debugging and error-solving
Even experienced theme creators are plagued by bugs. On Redmi 8, a common problem may be incorrect display of icons in the settings menu or a theme “meet” after a reboot. If the theme doesn’t apply, check the system logs or try to clear the theme app’s cache.
One common mistake is to size the images incorrectly, so if the icon is stretched or has black fields, double-check its original size in pixels, and the problem may lie in the bit file description.xml, especially if you edited it manually in a text editor.
If the phone is slowing down after installing the theme, you may be using too heavy graphics or unoptimized scripts for the lock screen. Simplify graphics and reduce the number of animations.
💡
Careful inspection of each modified file before final assembly saves debugging hours and prevents potential interface errors.
