Thanks for all the info, I was having the same issue with my Sprint Touch Pro, and after 25 times via USB and a couple of microSD attempts, I was finally able to get the MightyROM5 to install from my microSD.
Previous attempts had looked good, and went 100%, but got locked into a reboot loop.
I'm not sure what was different, but I did reformat the microSD and rename the ROM to RALPHIMG.nbh, but I could not get the EnergyROM to work.
Thanks to Everyone involved. Off to resync and setup email, etc.
