GTF, FGX - where they found no bugs in firmwares, so never needed to upload a patched version for the dealers. Their download site does not host original version firmwares (everyone got at least that version already installed in the module in their new car). So you can't "convert" an FG2 cluster to a FGX one, even though the software is the only difference.

Today, after the best part of 7 days working solid on this, I have extracted the two FGX firmware areas, signal-config and firmware-exe, and the Central Config cluster at the end. The first 20KB (the primary boot loader) cannot be extracted... I guess that's not important (I assume they are all the same, since the FG2 secondary boot loader works on the FGX... Now to try it on a FG[I]).
The RAM cannot be extracted either, so, no EEPROM copy without disassembly of the IPC module to get physical access.
That's pretty much the usual method though, so I'm very happy with what I've got now.
