How to Perform a TCL TV Software Update Using a USB Drive
Keeping your TCL TV’s software (firmware) up to date is crucial for optimal performance, access to new features, bug fixes, and security patches. While most TCL TVs update automatically over the internet, there are situations where a USB update is necessary or preferred:
8. Limitations & Risks
- Warranty void – Using unofficial firmware may void warranty.
- Brick risk – Power loss during update can permanently damage TV.
- No progress bar for some models – Only a spinning wheel or blinking LED.
- USB 3.0 incompatibility – Some TCL TVs only read USB 2.0 drives.
- File size limit – FAT32 cannot hold files >4GB (split archives needed).
(this tells the TV to look at the USB port instead of the internet) [3, 4].
