If you are looking for a specific version (like upgrading from Android 9 to Android 11), you may need to use a USB drive.

You will need a USB drive formatted to the FAT32 file system. Insert the USB drive into your computer. Right-click the drive in "My Computer" and select "Format". In the "File System" dropdown menu, choose FAT32 and start the process. Step 2: Download the Firmware. Go to the TCL support website for your region. Use the search bar to look for your model number, "50EP660". Download the firmware for the TCL 50EP660 to your computer. The file will likely be a compressed .zip archive. Step 3: Copy the File. Copy the firmware file (do not rename it) directly to the root directory of your formatted USB drive. The root directory is the main folder of the drive, not inside any sub-folders. Step 4: Install the Update. Turn off your TV and unplug the power cord from the wall outlet. Insert the USB drive into one of the USB ports on the side or back of the TV. Plug the power cord back in. Step 5: Initiate Installation. Follow the on-screen instructions. On most TCL models, the update will start automatically. If it does not, navigate to Settings > System > About > System Update and select "USB Update" . Wait for the installation to complete and the TV to restart.
