LeTV S50 Air: Install a Sofa Butler via USB Drive
If you're looking to install third-party apps on your LeTV S50 Air, one of the easiest ways is by using a USB drive. This guide will walk you through the entire process step by step.
**Installation Steps**
1. **Download the Sofa Butler Installation File** – Visit the official website of Sofa Butler and download the installation package. The download links are usually available for versions V4 and V5. Make sure you get the correct version compatible with your TV model.
2. **Copy the File to a USB Drive** – Once downloaded, copy the installation file to a USB flash drive. Insert the USB into your LeTV S50 Air, but don’t open the file manager just yet.
3. **Access System Settings** – Navigate to the "Settings" menu and select "System Settings." From there, go to the "General" section.
4. **Enable Unknown Sources** – Look for the "Security" or "Safe" settings and enable the option for "Unknown Source Applications." This allows the TV to install apps from outside the official app store.
5. **Open File Manager** – Return to the home screen and open the "File Management" app. Select the "Storage Device" option, then choose "External Storage" where your USB drive is connected.
6. **Install the Sofa Butler App** – Locate the Sofa Butler installation file on the USB drive, tap it, and follow the on-screen instructions to complete the installation.
Once installed, you can access a wide range of live and on-demand content through the Sofa Butler app. It also acts as an app market, allowing you to download various streaming services like Tencent Video, Youku, and more.
**Troubleshooting Tips**
- If your TV doesn't recognize the USB drive, try formatting it to FAT32 (make sure to back up any data first).
- If the installation fails, restart your TV and repeat the steps. Sometimes a simple reboot can resolve issues.
With this setup, you can enjoy a more flexible and personalized smart TV experience. Whether you're watching live TV, on-demand videos, or using specialized apps, the Sofa Butler makes it easy and convenient.
For the best experience, consider pairing your TV with a TV box or using a streaming stick like a TV Cat for smoother performance. Enjoy your upgraded smart TV!
