I have now also tried that FVMAIN.fv that you linked to. In each case, the FVMAIN seems to do the update, but Galileo still will not boot. EFI is no longer available either in case that was not clear earlier.
I dont't have a JTAG programmer unfortunately...
Here is the output from the latest attempt. In each case, I see the same failure to boot sequence and the board select prompt. I do not have a jumper to the recovery resistor.
