The TCL L40S6500 relies on stable, correctly matched firmware for all core functions. Unlike high-end Android TV models, it receives few official updates, so preserving a backup of the original working firmware is wise. When updating or recovering, prioritize:

If the TV experiences persistent software-related issues (e.g., smart features broken but inputs work), consider using it as a basic display via HDMI, bypassing the internal OS entirely.

Always consult a professional repair technician if you are unsure about disassembling or flashing firmware. Improper flashing can permanently damage the mainboard.

Yes, but not recommended. Newer firmware often contains critical patches. However, if a new update introduces bugs (e.g., worse picture quality), you can downgrade by following the same USB method but with an older firmware package. Note that downgrading may wipe all user data and could void warranty.
