I'm not really meaning to be cryptic, but i don't really know a good way to explain it. The radio is actually made of different parts and the part that i can actually access on my phone at this moment is still the same as the one from the 3.16 update i did. 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.
So to clarify, you bricked the other mogul in an attempt to go from 3.35 official Sprint Rom to the 2.17 official Sprint ROM? did you flash bootloader 1.20 first? nothing to do with wM5? perhaps thats another story/brick? if so, soon you will have that patio !!!

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.
Thank you for that explanation!!!
So you are saying that even if 2.17 Flashback appears to be successful,
that the Radio would prolly still be 3.35 or 3.27 (depending on the Radio prior)

Hmm, RAM addresses, hex dumps, man i need to learn more!!!
If only i had an xtra 6800 for experimenting...

Upgrading is different though, right?
you can upgrade 3.16 to 3.35 and that will overwrite the GPS 3.27 Radio to 3.35, correct? can you also go from Radio 3.35 -> 3.27 or do you think that would brick as well?

Thanks again for both of your replies,

P.S. have you see this ->
