I have since put on the 3.35 and went to revert to the 2.17 (bricked in this process, but there were other variables). There are all sorts of different combinations of those parts that could have occurred, but i can't really backtrack at this point and as it's bricked i can't even access all of it to verify. This is what i mean by radio not being over written and my one statement of "it can't be done." =) I'm actually looking at the ram and doing a hex dump looking for version strings and comparing to rom radio updates for this info.
and good ole' shadowmite...

If you flash a 2.17 rom onto a 3.x radio device, it might work and appear to be back to normal, but I highly doubt you have flashed back the radio as we have specifically tried to accomplish this for days without success.

Be warned, this is dangerous territory as cokey himself has bricked a device in this process.
