Theme Cozy for TrimUI Brick

for TrimUI Brick（CrossMix OS）

Preview

Instructions - Theme files only

Download the project file.
Copy the folder CozyBrick/ThemeFiles/Themes/Cozy to your SD card's Themes folder.
Settings -> Themes -> Cozy

Instructions - fully - App install

Important

Your TrimUI Brick's version need to be CrossMix v1.3.0 (Brick branch)
You can find the latest version in https://github.com/cizia64/CrossMix-OS/tree/Brick

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 CozyBrick folder into your SD card's Apps folder.
Insert the SD card into your Brick device and reboot it.
Switch to the Apps tab, where you’ll see an app named CozyBrick.
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)
Navigate to System Tools -> Theme -> Cozy to switch to the Cozy theme.
Done! Enjoy your new theme.

The app icon in Brick has been using topicon as its icon now, and the icon layout is not compatible with the original "icon" option in the app's config.json file. And CorossMix also has not made adjustment for this. So I have decided to use "icon" as the app's icon. After you fully install this theme into your device, you will find that the icons of the apps that come with the stock are different from the others in size. That's because they are using "topicon" as their icons. So here is what you need to do:

Open SSH. Apps -> SystemTools -> NETWORK -> SSH (enable it) Connect your device with SSH. User: root, password: tina
Go to the folder /usr/trimui/apps/ You will find four apps in this folder:
- fn_editor
- moonlight
- player
- usb_storage
There is a config.json file in each app folder. What you need to do is open those files and replace "icon" in them with the "topicon" content, leave "icontop" to "" Like this:
```
{
"label":"Media Player",
"label.ch.lang":"...............",
"icon":"ic-media-player.png",
"icontop":"",
"launch":"launch.sh",
"description":"TRIMUI Media Player",
"description.ch.lang":"TRIMUI Media Player"
}
```
After this, enter an app and then exit it. You will see the changes. The size of the system icons will be the same as that of the other apps.

Instructions - fully - Manual install

Important

Your TrimUI Brick must be running version 1.3.0.
You can find the latest version at https://github.com/cizia64/CrossMix-OS/tree/Brick

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.

Download the project file.
Copy the folder CozyBrick/ThemeFiles/Themes/Cozy to your SD card's Themes folder.
On your TrimUI Brick, navigate to: Settings -> Themes -> Cozy.
The basic theme files will now be applied
