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 : Download ONIDA LEO50FSAIN Software USB part09 rar
The TV should then automatically begin the "USB Upgrade" process. If you have downloaded the multi-part RAR files,
: 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 ).
