You can change the font to Xiaomi Redmi 9 Pro with both standard MIUI and third-party tools — but each method has its limitations and potential risks. In this article, we will analyze all the current ways from safe change through themes to deep customization with root rights. It is important to understand that not all fonts are equally well displayed on high-resolution screens (for example, FHD+ 2340×1080 on Redmi 9 Pro), and some methods can lead to system failures.
The main problem with Redmi 9 Pro users (M2007J3SC/M2007J3SI) is the limited choice of fonts in standard MIUI 12/13/14 firmware. The manufacturer blocks custom font installation without additional manipulation, but workarounds exist. Below you will find step-by-step instructions for each method, a comparative table of their pros and cons, as well as answers to frequent questions about compatibility and security.
1. Change font through standard MIUI themes
The safest and most recommended way is to use the built-in MIUI Theme Store, which is root-free and warranty-free, but the choice of fonts is limited to official collections. Here's how it works:
Open the Topic app (Brush icon) and go to the Fonts section, where you will see free and paid options, sorted by categories: handwritten, minimalist, 3D-Note that some fonts may not support Cyrillic — check other users' reviews before installing.
- 🔍 Pros: No technical skills required, reversible process, no impact on performance.
- ⚠️ Cons: Limited choice (about) 50-100 Fantasy, some of the options are paid (from 50 before 300 ruble).
- 📱 Compatibility: Works on all versions MIUI Redmi 9 Pro, including global and Chinese firmware.
⚠️ Attention: After update MIUI Before the new version (for example, from 12 to 13), the installed fonts can be reset to the standard. To avoid this, save the theme you like in My themes → Chosen.
2. Installation of fonts through APK-files without root)
If built-in options are not enough, you can manually install the font through.ttf files. This method requires activation of the developer mode and use of the iFont application (available on Google Play).
Step-by-step:
- Download the iFont app from the official store.
- Download your favorite font in.ttf or.otf format (for example, from DaFont or Fontsquirrel sites).
- Open iFont, import the downloaded file and select the Install option.
- Go to Settings → Display → Font and select a new option from the list.
Download iFont from Google Play| Check font compatibility with MIUI| Backup your current font | Activate Developer Mode (optional, but recommended)

List of proven fonts running on Redmi 9 Pro:
| Name of font | Type | Cyrillic support | Compatibility with MIUI |
|---|---|---|---|
| Google Sans | No serifs. | Yes. | Complete. |
| Product Sans | Corporate | Yes. | Partial (Glitches on the menu) |
| Comic Neue | Handwritten | Yes. | Complete. |
| Fira Code | Monowidthy | No. | Only for Latin. |
⚠️ Note: When installing fonts via iFont, some system applications (such as Camera or Gallery) may not display the text correctly!
3. Change font through ADB (for power users)
The Android Debug Bridge (ADB) method allows you to install a root-free font, but requires a computer connection and basic command line knowledge, which is suitable for users who want to use fonts that are not available in the MIUI Theme Store or iFont.
Instructions:
- Activate Developer Mode (7 times click on the MIUI version in Settings → About Phone).
- Enable USB debugging in Settings → Additional → For developers.
- Get Redmi on board. 9 Pro to PC and execute the command: adb shell"pm grant xy.zed.lnx ifont com.android.theme.icon_pack"
- Download the font in.ttf format and place it in the /sdcard/Download folder.
- Run the command to install: adb push /path/to/font.ttf /data/local/tmp/adb shell"su -cp /data/local/tmp/font.ttf /system/fonts/"adb shell"su -c'chmod 644 /system/fonts/font.tf'"
What if the ADB can’t see the device?
Critical! Incorrect use of ADB can lead to bootloop (a looped system boot).Before executing commands, back up your data through Settings → Additional → Backup and Reset.
4. Install custom font with Magisk (root)
For users with an unlocked bootloader and Magisk installed, the most flexible method is available - modules for changing system fonts, which allows you to install any.ttf files, including unofficial modifications, but requires root rights and voids the warranty.
Step-by-step:
- Unlock the Redmi 9 Pro bootloader via Mi Unlock Tool (the official utility from Xiaomi).
- Install Custom Recovery (TWRP) and get root rights through Magisk.
- Download the FontManager or TypeFace module from the Magisk Modules repository.
- Place the.ttf font file in the /sdcard/Download/Fonts folder.
- Reboot to Magisk, activate the module and select the font.
- ✅ Pros: complete freedom of font choice, support for animations and color gradients.
- ❌ Cons: the risk of disrupting the system, possible problems with OTA-update.
- 🔧 Nuance: some banking applications (SberBank, Tinkoff) can block work on rooted devices.
💡
Before installing the Magisk module, check its compatibility with your version of MIUI on the XDA Developers forum or 4PDA. Some modules conflict with Android 12+ firmware.
5. Alternative methods: run fonts via Substratum or LSPosed
For users who don’t want root rights but need advanced customization, frameworks like Substratum (for Android 8-9) or LSPosed (for Android 10+) are suitable, allowing you to change fonts without deep interference, but require the activation of ADB or Shizuku.
Example of settings via LSPosed:
- Install LSPosed and FontRevive module from the repository.
- Activate the module in the LSPosed settings.
- Select a font from the built-in gallery or upload your.ttf file.
- Reset the device.
⚠️ Note: Using LSPosed may conflict with some applications that use SafetyNet (e.g. Google Pay or Netflix).Before installing, disable these services or use the MagiskHide Props Config module to mask the use of the LSPOSED.
Comparison of all methods: which one to choose?
To make it easier, we have compiled a table comparing all the methods described. Keep in mind that Redmi 9 Pro based on Snapdragon 720G can react differently to customization depending on the firmware version (global, Chinese, EEA).
| Method | Need root? | Risk to the system | Reversibility | Support for OTA |
|---|---|---|---|---|
| MIUI Theme Store | No. | Absent. | Yes. | Yes. |
| iFont (APK) | No. | Low. | Yes. | Yes. |
| ADB | No. | Medium. | Yes (when backing up) | Yes. |
| Magisk modules | Yes. | High-pitched | Partially. | No. |
| LSPosed | No (but Shizuku is needed) | Medium. | Yes. | Yes. |
💡
For most Redmi 9 Pro users, a combination of the two is the best solution. MIUI Theme Store (for basic fonts) and iFont (for advanced selection). ADB Magisk is only suitable for experienced users who are ready for potential risks.
Frequent problems and their solutions
When changing fonts to Redmi 9 Pro, you may experience errors, and here are the most common ones and how to fix them:
- 🔄 Font not applied: restart the device or clear the cache in Settings → Annexes → Application management → Topics.
- 📵 Hieroglyphs instead of text: font does not support Cyrillic – choose another option or download the multi-byte version (.ttc).
- ⚡ System lags: some fonts (especially with animation) increase the load on the system GPU Adreno 618: Go back to the standard font or choose the lighter option.
- 🔒 Blocking Banking Apps: If you use root or Magisk, activate MagiskHide and add the app to exceptions.
If the device starts to overheat or discharge quickly after changing the font, check the CPU load through Settings → Battery → Battery Use. Some custom fonts (such as those with shadows or gradients) can increase power consumption by 5-15%.
