DINC 2 won't start

[evanseor]

I have a dinc2 which is my 5th replacement phone since the end of January.  Yesterday it locked up and I couldn't even get it to load in Safe Mode, so I did a factory reset.  It just did the same thing again.  It seems to lock up and then I take out the battery.  It powers up, but then goes into a boot loop... Is there anything that I might be missing?
