Recommendation
- Install security updates if offered – they rarely cause major issues.
- Avoid updating right before watching something – do it when you can leave the TV alone for an hour.
- If the TV works perfectly now and you don't use smart features (e.g., you use a Fire Stick/Apple TV) – you can safely skip updates.
- If you're stuck on a very old version (e.g., 2019 firmware) and have Wi-Fi/HDMI issues – try the USB update method from TCL’s support site using your exact model number.
