Cannot update firmare 40mm stm on 5dII help please

Ok.

I'm not an idiot.

EF005120.lfu is the firmware I d/l from canon site. It's for the windows 7 x64.

fine.

so i format the cf card; copy to root and when i access the menu sction of firmware 2.12 I get message:

"memory card containing firmware is required to update".

i did the remove battery/lens trick and no luck.

also it;s interesting the 5d2 does not show me what the existing lens firmware is as well.

help please appreciated.

oh i tried the eos utility and it would not update firmware since 40mm lens is not a ",fir" file but ".lfu"
