Stock rom links for cdma Touch PRO

[regression]

Hi, I am familiar with flashing custom roms (ie using a RUU_signed.nbh file, running ROMUpdateUtility.exe). But, I want to go back to stock. What is the difference between the dumped and shipped (signed) roms on the first post in this thread?

It looks like the dumped roms are a .nbh file, which I think I can use.

But the shipped is exe. Do I put the phone into boot loader mode, connect to my PC and run the exe?

Thanks. I tried looking through this thread, but I am sure I missed the above info.....
