🛠️ TCL Smart TV Software Updating Procedure

Follow the steps below to safely update your TCL Smart TV firmware using a USB drive:

✅ Step-by-Step Instructions:

  1. Copy the firmware (ZIP or IMG file) to a FAT32 formatted USB stick.
    🔹 Maximum supported size: 16GB
  2. Insert the USB stick into the TV’s USB port.
  3. Press and hold the POWER button on the TV’s physical panel (not the remote).
  4. While holding the POWER button, turn on the TV.
    The TV will detect the firmware file and enter the upgrade interface automatically.
  5. Once the upgrade starts, release the POWER button.
  6. Wait patiently until the update process completes.
    ⚠️ Do not power off or remove the USB during the process.

📌 Notes:

  • Always ensure the file is copied to the root directory of the USB.
  • Do not rename or extract ZIP firmware files unless mentioned.
  • Use only official fire bin files or firmware supported by your TV model and mainboard (e.g., MS86, RT51).
