How to change the font on Xiaomi Redmi 9T: from standard settings to ADB-team

Why users want to change the font to Redmi 9T and what to know before you start

Xiaomi Redmi 9T with MIUI factory firmware offers a limited choice of default fonts — usually Roboto, MiSans or regional variants like Noto Sans CJK. For many users, the standard font seems too “childish”, unreadable at a small size or simply does not fit into the overall interface style, especially after the MIUI 12/13 update, where the design has become more aggressive in terms of typography.

Before you start making changes, consider three key points:

• 📱 Version. MIUI matters: On Redmi 9T s MIUI 12.5 and later (e.g., through the Topic) methods work differently than on the MIUI 11. Check your version in Settings → The phone. → Version. MIUI.
• ⚠️ The risk of “bricking”: Methods with ADB or manual editing of system files can lead to loss of warranty and the need to flash through Fastboot if something goes wrong.
• 🔄 Reset to factory: Some methods (such as installing custom fonts through Magisk) require unlocking the bootloader, which automatically resets the phone.

If you're happy with minimal changes, start with standard MIUI settings. For deep customization, you'll have to use ADB or third-party utilities. Below, we'll take you through the simplest to the most risky.

Method 1: Change the font through standard MIUI settings (without root)

The safest way to do this, which works on all versions of Redmi 9T, is to use the built-in MIUI options. You can’t set up an arbitrary font here, but you can choose from pre-loaded options.

Instructions:

1. Open Settings → Display → Font size and style.
2. Slip on the Font item (on some versions of MIUI it is called font style).
3. In the list of available fonts, select the type you like: 📌 Roboto (standard for Android) 📌 MiSans (brand font Xiaomi) 📌 Noto Sans (to support Cyrillic and hieroglyphics) 📌 Casual or Handwriting (Decorative Options)

Confirm the change – the system will restart the interface (not the entire phone!).

If there are few options on the list, try updating the Themes app through Google Play or MIUI App Store. Sometimes additional fonts appear after the update.

⚠️ Attention: MIUI 13+ Some decorative fonts (such as Handwriting) may not display correctly in third-party apps like Telegram or WhatsApp.

Method 2: Install fonts through the Themes app (without root)

Xiaomi’s Themes app allows you not only to change wallpaper and icons, but also to download additional fonts, which works without root rights, but requires an Internet connection.

How to install a new font:

1. Open the Themes app (the icon with a brush on your desktop).
2. Go to the Fonts section (may be in the Profile menu) → My resources).
3. Scroll through the list of available fonts. Popular options: 🎨 SF Pro (similar to the iPhone font) 🎨 Product Sans (like Google) 🎨 OnePlus Slate (minimalist) 🎨 SamsungOne (like on the Galaxy)

Apply

If the desired font is not in the list, try:

• 🔍 Enter the font name in the search within the Topics app.
• 🌍 Switching the region in your Mi Account to India or Europe – sometimes this opens up access to additional fonts.
• 📥 Download a.ttf font from a trusted source (like Google Fonts) and try to install it through Topics → My resources. → Local (not available on all versions) MIUI).

⚠️ Note: Fonts downloaded through Topics may be reset after major updates MIUI. We recommend saving backup copies of your favorite options in.ttf format on the cloud disk.

Method 3: Using ADB to install custom font (without root but with PC)

If you don't like the standard methods and you don't have root rights, you can use ADB (Android Debug Bridge), which allows you to install any typeface in.ttf format, but requires you to connect your phone to your computer.

Step-by-step:

1. Preparation: 🖥️ Install. ADB and Fastboot Tools on PC. 📱 Enable Developer Mode on Redmi 9T: Go to Settings. → About the phone and 7 times tap on the version MIUI. 🔌 Turn on Debugging. USB In Settings → Additionally. → For developers.
2. Connection: Connect your phone to your PC via USB-Cable (original preferably) Select File Transfer Mode on your phone (MTP). Open the command line (Windows) or the terminal (macOS/Linux) and type: adb devices If the device appears in the list, go further.

Installation of font:

• Download a font in.ttf format (like Google Fonts) and rename it to custom_font.ttf.
• Place the file in the folder with adb on the PC.
• Follow the commands in turn: adb push custom_font.ttf /sdcard/ adb shell su mount -o rw,remount /system cp /sdcard/custom_font.ttf /system/fonts/ chmod 644 /system/fonts/custom_font.ttf rm /system/fonts/Roboto-Regular.ttf ln -s /system/fonts/custom_font.ttf /system/fonts/Roboto-Regular.ttf reboot
• Install the module via Magisk Manager: 1. Open Magisk → Modules → Install from storage. 2. Find the downloaded module (.zip file) and select it. 3. Reboot the phone.
• Once you reboot, the font will change. If you want to return the standard version, delete the module in Magisk Manager and restart.

Advantages of this method:

• ✅ The ability to install any typeface, including exotic ones (e.g. Pixel Font or Windows 95).
• ✅ Easy switching between fonts via the module menu.
• ✅ No need to manually edit system files.

Disadvantages:

• ❌ Requires an unlocked bootloader that resets the phone.
• ❌ Some modules may conflict with other modifications (e.g., Xposed).
• ❌ Updates MIUI They can break the work of modules – you will have to reinstall them after the update.

💡

Before installing the module, back up the current font. To do this, copy the folder through Root Explorer. /system/fonts/ on SD-This will help you quickly restore the standard font if something goes wrong.

Method 5: Manual editing of system files (for experienced ones only)

This is a tool that works for those who are willing to work with system files manually, and allows you to install any typeface, but requires root rights and accuracy — an error can lead to a bootloop.

Step-by-step:

1. Download the font in.ttf and rename it according to the file to be replaced. e.g.: To replace the main font: Roboto-Regular.ttf To replace bold: Roboto-Bold.ttf To replace monowire: DroidSansMono.ttf

Example of commands to replace through ADB (if there is no root manager):

If after restarting the phone does not turn on or the font is displayed curved:

• 🛠️ Try to boot up in Safe Mode (hold the power button). → long-tail → Safe Mode).
• 🔄 Return the original font files through TWRP or ADB Sideload.
• 📥 Fly your phone through Fastboot if the system doesn’t boot.

⚠️ Note: Some fonts (such as high contrast or serifs) may not read well on Redmi screens 9T permittingly HD+. Before installing, check the font on a PC with similar resolution (720p) or in an Android emulator.

How to return a standard font if something goes wrong

If after experimenting with fonts, the interface became unreadable, applications are crumbling or the phone does not load, use one of the recovery methods:

If the phone is not switched on:

1. Load into Recovery mode: Turn off the phone, then press Power + Volume up.
2. Connect your phone to your PC and use it ADB Sideload to download original font files: adb sideload font_fix.zip (where font_fix.zip — file-book).
3. If Recovery is custom (TWRP), you can manually replace files in /system/fonts/.

If nothing works, the last option is a full Fastboot flashback, and instructions for Redmi 9T can be found on the Xiaomi.EU forum.

💡

Always back up /system/fonts/ before experimenting, which will save you recovery hours if the font breaks the system.
