tl;dr I dropped my rooted and unlocked XT926 on the volume rocker, bent it so volume down was always pressed.  I didn't want to be permanently stuck in Safe Mode so I took it apart, bent the rocker to its original shape, put it all back together, and turned the phone back on.  Here's where the trouble started.

The phone makes it past the boot logo fine and starts to boot, but freezes every time at a certain point.  I thought it was a ROM issue (PAC 4.3 at the time) so I tried every trick in the book, wiping everything I could and reinstalling the zip.  Still no luck.

I have since tried using both Mattlgroff's utility and House of Moto, both of which worked fine.  Now I have the "warning" boot logo for unlocked bootloaders and the stock boot animation (and stock recovery), but I STILL get stuck at points very close to each other in the boot process.

Could I have mucked something up while taking the phone apart?  Like attached a ribbon cable incorrectly, or scratched something, that would cause this particular problem?  I'm kind of at a loss at this point and am considering just taking it apart again and putting it back together to see if anything changes.

 

Thanks for any and all assistance!

UPDATE:

I found a kernel panic message under /data/kernelpanics:
