: You cannot use part04.rar alone. To successfully extract the firmware ( .bin or .img file), you must download all parts of the archive and place them in the same folder.
: Installing the wrong firmware can "brick" your TV, making it unbootable. Always verify that your TV's internal board number matches T8C2 before proceeding.
: Typically, the extracted firmware is placed on a FAT32-formatted USB drive. You then plug the drive into the TV and initiate the software update process (usually by holding the power button while plugging in the TV).
: Right-click on part01.rar using a tool like WinRAR or 7-Zip and select "Extract Here." The software will automatically pull data from part04 and all other segments to recreate the original file.
