If you have downloaded the multi-part RAR files, follow these general steps to update your TV:

: Format a USB flash drive to FAT32 . Copy the extracted firmware file directly to the root directory (don't put it in a folder). Install via USB :

: Once complete, the TV usually restarts. You may need to perform a "Reset Shop" or "Reset All" in the settings menu to finalize the installation.

Never turn off your TV or remove the USB drive during the update, as this can permanently damage (brick) the device.

The TV should then automatically begin the "USB Upgrade" process.

: Download every part of the software (part01 through the final part). Place them in one folder on your computer and use a tool like WinRAR or 7-Zip to extract "Part 01"; this will automatically combine all parts into the final firmware file (usually ending in .bin or .pkg ).
