If you are trying to recover a failed Ktag flash, Ktag most likely will not recover it. You will be better off recovering it with a .ctz file. And if EFI Live don't see a serial number it may not either in that case hpt will flash it.

That is incorrect Mike, EFILive will happily recover an ECM as long as the file you are using is not S/N or VIN locked, any time people have run in to this issue of not being able to recover an ECM that has been the reason, in the trouble shooting for the error that comes up when this happens it even says to use a file that is not VIN or S/N locked (because they cannot be obtained from the ECM when it is in bootmode).

From my experience from the ecm's sent to me is if EFI don't recognize it is in recovery mode then it wants to see a serial number to license the ecm and if there is no serial to license it will error out.
