To update your Hisense TV firmware via USB, you generally need to download the specific update file for your model from the official support site and use a FAT32-formatted drive. Preparation

Identify Your Model: Check the sticker on the back of your TV or look under Settings > Support > System Info.

Format Your USB: Use a PC to format a USB flash drive (ideally 8GB or larger) to FAT32.

Download the Firmware: Visit the Hisense Support page, enter your model number, and download the .zip or .pkg file. Installation Steps

Extract the File: If the download is a .zip file, extract it. Copy the main file (usually ending in .pkg, .bin, or .ota.zip) directly to the root directory of your USB drive (not inside a folder).

Plug in the USB: Turn off your TV and plug the drive into the USB 1 or USB 2.0 port. Initiate the Update:

Method A (Automatic): Unplug the TV from the wall, hold the Power button on the remote, and plug the TV back in. Continue holding until "Software Updating" appears.

Method B (Menu): Turn the TV on, go to Settings > Support > System Update > Upgrade from USB.

Wait: The TV will show a progress bar. Do not turn off the power or remove the USB until the TV reboots and returns to the home screen. Important Tips

Check Model Suffixes: Ensure the firmware matches your exact model version (e.g., 55U6G vs. 55U6H) to avoid "bricking" the device.

Direct to Root: The TV will not find the update if it is buried inside folders on the USB drive.
