: You cannot use "part03.rar" alone. You must download all parts (part01, part02, etc.) into the same folder and extract only the first part to reconstruct the full .BIN file.

: While NAND dumps are usually for hardware programmers, general firmware updates can sometimes be found on the TCL SEMP Support Page by entering your TV's serial number. Important Installation Notes

: Ensure the "MAC2HG" or board number on your TV matches the file, as using the wrong firmware can result in a distorted image or a "bricked" device.
