This tutorial is specifically designed for the TCL L43F3390A-3D TV model. While it may also work for other TCL TV models, it's recommended to verify compatibility before proceeding.
**Installation Process**
1. Download the Sofa Butler installation file onto a USB drive or SD card.
2. Insert the USB drive or SD card into your TCL L43F3390A-3D TV.
3. Navigate to the "Software Recovery" option and open the installation file.
4. Once installed, you'll be able to access the Sofa Butler app on your TV.
**Step-by-Step Guide**
1. Search for "Sofa Manager" on Baidu or directly download the Sofa Butler package using this link: [http://app.shafa.com/shafa.apk](http://app.shafa.com/shafa.apk).
2. Copy the downloaded APK file to a USB drive or SD card.
3. Create a new folder named "TVManager" on the storage device. Inside it, create a subfolder called "backup" and place the APK file there. If you're using an existing SD card, check if the "backup" folder already exists.
4. Open the TV Guardian or TV Steward app, then go to the "Software Management" section.
5. Select "Software Recovery" to start the installation process.
6. Locate the Sofa Butler APK in the backup folder and click "Install" or "Resume." After a short time, the installation will complete.
7. You can now find the Sofa Butler app under the "Applications" or "All Apps" section.
**Troubleshooting Tips**
If your TV doesn't recognize the USB drive, try formatting it in FAT32 format first. Make sure to back up any important files before formatting. If the issue persists, try using a different USB drive.
If the installation fails, restart your TV and repeat the steps. If you still have trouble, feel free to join the official Sofa Butler QQ group for further assistance.
Once successfully installed, open the Sofa Butler interface to start downloading and managing your favorite TV apps.
For an enhanced viewing experience, consider using platforms like Tencent Video, HDP Live Streaming, or other smart TV apps available through the Sofa Butler. Enjoy a wide range of content tailored for your smart TV!
