Going back to 2.17, Do I need an old radio rom?

[omniphil]

I'm also having the data connectivity issues so I want to go back to the 2.17 factory Sprint rom, I have the factory rom and I have the "Relocker", do I also need the original radio rom, or does the Sprint rom have that in it as well? (I upgraded to the 3.27 radio rom)

In what order should I install these roms to go back to factory properly?

Thanks!
