Theme Cozy
for TrimUI Smart Pro(CrossMix OS)




Instructions - Theme files only
- Download the project file.
- Copy the folder
CozyInstaller/ThemeFiles/Themes/Cozyto your SD card'sThemesfolder. - Settings -> Themes -> Cozy
Instructions - fully - App install
Important
Your TrimUI Smart Pro's version need to be v1.3.0
You can find the latest version in https://github.com/cizia64/CrossMix-OS
It would take several copy-and-paste actions to apply a theme, so to make the process more convenient, I’ve created an app to handle it.
You can use this app by following the instructions below.
-
Download the project file.
-
Place the
CozyInstallerfolder into your SD card'sAppsfolder. -
Insert the SD card into your TSP device and reboot it.
-
Switch to the Apps tab, where you’ll see an app named Cozy Installer.

-
Open the app to view the instructions, as shown below:

-
Press A to automatically install the Cozy theme onto your SD card. This includes:
- theme deploy file
Cozy.sh - theme files
- replace all app's icon into cozy style (irreversible)
- theme deploy file
-
Navigate to System Tools -> Theme -> Cozy to switch to the Cozy theme.
-
Done! Enjoy your new theme.
Instructions - fully - Manual install
Important
Your TrimUI Smart Pro must be running version 1.3.0.
You can find the latest version at https://github.com/cizia64/CrossMix-OS
The process of manual installation is exactly the same as app installation.
Therefore, I recommend using the app to install this theme.
Only consider manual installation if the app installation is not feasible for you.
This situation may arise if you’ve made significant changes to CrossMix OS's file structure.
