TCL L48C1-UDG installs third-party applications via USB stick
This tutorial is specifically designed for the TCL L48C1-UDG model. While it may also work for other TCL TV models, please refer to the official documentation for your specific device.
**Installation Process**
1. Download the Sofa Butler installation file to a USB drive or SD card.
2. Connect the USB drive or SD card to your TCL L48C1-UDG TV.
3. Open the installation file using the "Software Recovery" feature.
4. Once installed, you can access the app from the main menu.
**Step-by-Step Guide**
1. Search for "Sofa Manager" on Baidu and visit the official website to download the Sofa Butler package. Alternatively, click [this link](http://app.shafa.com/shafa.apk) to directly download the APK file.

2. Copy the downloaded .apk file to your USB drive or SD card.
3. Create a new folder named "TVManager" on the USB drive or SD card. Inside this folder, create a subfolder called "backup" and place the Sofa Butler APK in it. If you're using an existing SD card, look for the "backup" folder directly.
4. Navigate to the TV Guardian or TV Steward app on your TCL TV. Open the app and go to the "Software Management" section.

5. Select "Software Recovery" and locate the Sofa Butler APK in the "backup" folder. Click "Install" or "Resume" to begin the installation. After a few seconds, you’ll see a confirmation that the installation is complete.

6. Once installed, you can find the Sofa Butler app under the "Applications" or "All Apps" section.

7. Open the Sofa Butler interface to confirm the successful installation. From here, you can download and manage various TV applications.
If your TV doesn’t recognize the USB drive, try formatting it in FAT32 first (make sure to back up any existing data before doing so). If the issue persists, try using a different USB drive.
If the installation fails, restart your TV and repeat the steps. If you still encounter issues, feel free to join the official Sofa Butler QQ group for further assistance.
Enjoy watching on-demand videos and live broadcasts on your smart TV. We recommend using HDP Live Streaming or Tencent Video TV for the best experience. Explore more content with Fun Smart TVs, boxes, and other platforms available through the Sofa Butler app.
