To download and install the Haier LE55U6500UAG Firmware part04.rar

If you have already acquired the full set of .rar files (part01 through part04) from a third-party technician forum or collection:

: Place all parts in the same folder. Right-click on "part01.rar" and select Extract Here ; this will automatically pull data from part04 and other volumes to create the final firmware file (usually ending in .bin or .pkg ).
