Updating Software Version on GMA3 onPC node

I am trying to match my node software version to my PC version. I am currently running v.2.3.0.4.
In the tutorials it says to copy the "EFI, "ma" and "update" files out of the ma install folder and put into USB. I do not have "EFI" nor "update" in my downloaded folder on my PC. This happen to anyone?

Also, can you just update node directly through the program on PC?
