Who I have the same questioned this topic

Was using my Droid Pro today when it froze up.  I pulled the battery to reboot it and upon doing so the phone has remained stuck on the startup animation loop.

I have tried any tricks that I can think of, but nothing seems to get it out of this loop.

I have attempted wiping the cache clean.   It just freezes and does nothing.

I have tried a factory reset.  It seems to do nothing either and just goes back to the phone startup loop.

Just wondering if anybody has any other suggestions or tips that may possibly work.  

Thank you.
