Locate the latest firmware download (usually a .zip or .bin file, or an Update.img file). Download the file to your computer. Step 3: Transfer the File to USB If the downloaded file is a .zip file, it.

Download the latest available zip package. If you cannot locate the file online, contact TCL Customer Support directly with your Model Number and Serial Number; they will email you a direct download link to the exact file. Step 4: Prepare the USB Drive

Warning: Formatting deletes all existing data on the flash drive. Ensure you back up any important files before performing this step. Step 3: Download the Correct Firmware File

Fix: The download was likely interrupted. Delete the file from your computer, clear your browser cache, and download the firmware package again.

Keep the file compressed. Copy the original .zip file directly to the root directory of your USB drive. Do not put it inside any folders.

Fix: Verify that the file is in the root folder of the USB drive and not tucked inside another folder. Ensure the USB format is strictly FAT32. Double-check that you did not accidentally rename the extension.

The TV will detect the file; select to begin the installation. Method B: Forced Update (TV is Off/Recovery) Power off the TV and unplug it from the wall. Insert the USB drive into the TV.

The TV will detect the file on the USB and prompt you to begin the update. Method 2: Force/Manual Update (Using Power Button)
