I've tried install using both methods described above and both methods result in a reboot loop and I have to do a restore of one of my backups. Any ideas?
I'm pretty sure. I went into the thread "Themes For The Ultimate Droid 2.5.0 - All Devices" and clicked on the theme for my device (Droid Incredible). I am trying to install the Renovated Axiom sixty6 theme. I have the UltimateDroid 2.5 rom which works great.
