Updating a TCL Roku TV via USB follows a different logic as it runs the Roku OS rather than Android/Google TV.

If you just want new features, use the OTA file via USB (Local Update). If your TV is crashing or acting strangely, use the IMG file for a clean slate.

Select (or USB Update depending on the software version).

Visit the official website or the standard Roku product registration page. Enter your TV's specific model number and serial number.

With the TV turned off, Leo plugged the USB stick into the side port. He held down the physical Power button on the TV frame and plugged the power cord back into the wall outlet. He didn’t let go of the button until the TCL logo appeared with a spinning circle and the words "Software Updating."

The safest place to get firmware is the official TCL support website. Navigate to the "Support" or "Downloads" section for your specific model. If you cannot find the official version, reputable community repositories (like XDA Developers or Telegram groups dedicated to TCL firmware) are common sources, though caution is advised.

Use a reliable USB 2.0 or USB 3.0 drive with at least 8 GB of capacity.

The system update can take anywhere from 5 to 20 minutes depending on the size of the firmware package.

If you give me your TCL model number (exact model code) and the file name you downloaded, I can give precise folder/file placement and the expected filename for the USB.

The USB drive must be formatted to FAT32. TCL TVs cannot read NTFS or exFAT formats for system updates.

. Larger drives or other formats like NTFS may not be recognized by the TV's recovery system.
