header error log when attemting firmware update

Can you please be more brief in your requests? I don't need so much info to be able to help you. Just ask the question!!

Maybe a little more detail would help. What is "header error log"? =^..^=

Printer firmware,Main firmware or the Lot???What??? What version??? Man, the questions keep coming. The correct panel message????

Wouldn't a header error indicate trying to load the wrong firmware to a machine, I think I had that once when I incorrectly assumed I had the firmware for the model I was working on already loaded onto the CF card. Luckily putting the correct firmware onto the card then reflashing worked fine.
