I am assuming you are talking about a fun USB programmer and using fun files.
Start the programmer software after connecting the USB lead to a pc.
Insert the card chip down. it will automatically erase the chip and determine the type of card.
There are three loading sections. Use the top one and the bottom one do not use the middle one.
The top one click on the icon to find your flash file probably V4.3 or 4.4 dot hex
Then click on the icon and select the other file probably dated or named and dated dot hex.
When both filenames are displayed click write and wait for the card to be programmed. You have given me an idea here so I may just do some screen shots when I have time and make a sticky. Good luck, any problems come back
