su




mount -o rw,remount /system




cp /sdcard/Download/YourFont.ttf /system/fonts/




chmod 644 /system/fonts/YourFont.ttf




reboot

If you only need to change the font on your desktop (not globally), use alternative launchers:

• 🌈 Nova Launcher + Nova Google Companion (allows you to change the font in the icons).
• 🎨 Action Launcher (built-in font support for widgets).
